I always change mine at the 600 mile mark right over to synthetic. This last vechile wife bought the wrong oil and lost reciept so it was stock oil for 600 miles, synthetic blend for 600 and then 100% synthetic from 1200 miles on out. Normaly though I just chage it to synthetic at 600 miles. The longest I have ever had a customer wait or I have waited is 1000 miles. Their are some that will tell you to wait until you have 3000-5000 miles for the rings to seat but that is really not needed. Rings will still seat just fine with synthetics. Todays engines are preety much broken in 250-500 miles easy. In some cases some engines are designed to seat the rings with in 15-20 minutes of driveing. The clearances between the bores and rings is much tighter then in years past, rings are tapered now to speed break in, rings are moly coated and in some cases heat treated stainless steel. Even compays that still use iron rings will usualy use a zink compound on them to keep them from welding micro beads on the the rings and cylinders. In the case of camshafts the first 20 minutes of the engines life is the key determineing factor. Valve guides wear at the same rate no matter what oil is used. So anytime you want to put synthetic oil in go for it!! Alot of vechiles come factory filled with Mobil-1. THe only company that I know of that still uses a propitary custom blended break in oil is Audi.

Regarding the use of Synthetic Motor Oils (Amsoil or Other) in brand new or rebuilt engines, it is recommended, however not mandatory, that the motor be initially operated with petroleum oil up to its first normal drain interval. The advantages of doing this are as follows.
New engines or engine components generate high wear metals to begin with and generally contain debris from machining and assembly. It is more beneficial to allow these wear metals to collect in an inexpensive motor oil than to circulate throughout the crankcase for extended periods in a synthetic motor oil. By operating the vehicle to its first drain interval with a petroleum oil, these wear metals and manufacturing debris collect in the oil and are then flushed out of the crankcase when drained. This allows for a much cleaner operating environment for the synthetic lubricant.
Within the first miles of operation, if there are any defects in the assembly or workmanship of the engine components, they may be corrected before installing the more expensive synthetic motor oil. Occasionally, rebuilt engines may have re-machined components or materials which can sometimes be mismatched. These problems will develop in a fairly short period of time. If excessive oil consumption, leaks, or any other problem is noted, this should be corrected prior to changing to Synthetic Oil.

There is nothing in a synthetic that keeps you from using it from day one. Wear metals for most engines level off on used oil analysis at about 5-8,000 miles depending on the driving environment. You do need to be aware, your warranty specifies an API approved oil. Not all of Amzoil products are API certified. According to a conversation with API 2 weeks ago, Amzoil did not have a multiweight that was approved. I would make sure if going with Amzoil that it does have the API certification on the bottle or you will void your warranty. I would appreciate a comment from the Amzoil Sponsor.

Wow!, cool info on Amzoil. I'd like to hear a response as well.
I have used Royal Purple 5/30 since 3,000 miles (41,000 now). I was told that it is best to wait until full break-in (2500-5000) miles.
Motors "seat" or "mate" better when new with conventional oil (this was in my wife's '03 Accord owners manual) because synthetics are too slippery, and the parts don't mate right.
I have never had any noise at start up with 5/30. I bet it's your filters anti-drain back valve. Frams are bad at this. I have been real pleased with K&N Gold oil filter #HP-2004.

So Darryl then what you are saying is that GM, Porsche,Mercedes,BMW,Lexus,Dodge are all idiots for releases more and more vechiles with synthetic oil and either semi-synthetic of fully synthetic trany fluids and diff fluids???? I guess that these cars, trucks and sports cars will never break in? What were they thinking???? A modern engine is vastly different in it's materials and slight nuances then engines built just 5-10 years ago!!! IF your new engine not a rebuild is not broke in by 600-1000 miles it was machined by monkeys and designed by dinosaurs!!! If you took an engine from 10 years ago and drove it home at 70-80 mph for 1 hour road strip right off the lot you would end up with a smokeing oil burning engine before warranty was now you can drive them off the lot like you just stole it with out any damage. The owners manual for my Dodge basicly recommended accelerateing hard and driveing normaly to break it in. In the 1980 you had to vary speed every 15 minutes, could not exceed 55mph for the first 500 miles, had to lock the hubs in for the first 500 miles, had to change oil at 500 miles and it was advised not to tow anything or drive for more then 45 minutes without stoping and the list went on and on and on. All of these crazy break in requirments are gone... If you change your oil and filter at 1000 you will be fine. Personaly I have always done it between 600-1000. If it that big of a deal do a wet compression test and dry compression test of each cyclinder new. Then do it at 1000 and if the rings have seated you will know. The accelerated debrie should be finished by 600-1000 miles as well. If your engine is still produceing huge wear particles beyound this point you have serious problems with the engine!!! Even if cylinder wear was reduced by 50% with a good synthetic your engine still wears so it will have no choice but to break in reguradless of oil used.

Message:
Larry L,
Good question. AMSOIL staffers have recently read some message boards with misinformation regarding this issue. Let me address API licensing, as well as the issue of warranties. Some AMSOIL motor oils are API licensed, some are not. If you're concerned about your warranty and feel pressures to use an API licensed oil, even after reading this answer, then the 5W-30 (XLF), 5W-20 (XLM) or 10W-30 (XLT) XL-7500 or our 15W-40 (PCO) API licensed oils should be your choice. If you are looking for an alternative to frequent oil changes or just want the best performing oil for your truck, then one of our top tier non-API licensed synthetic oils are for you. Read on, and decide for yourself.
API Licensing - Passenger Cars - What is it?
An API (American Petroleum Institute) license indicates that a specific motor oil formulation has passed the MINIMUM performance standards as defined by a series of laboratory bench, physical, chemical and engine tests. These tests were selected and minimum performance standards were set by the API Lubricants Committee to address specific areas such as engine wear, deposits, fuel economy, emissions, etc. The committee is comprised of representatives from automobile, oil and additive companies.
Additive companies, such as Lubrizol, Ethyl, Infinium and Oronite, develop licensed formulas that they offer to oil companies to re-license. It is inexpensive to re-license one of these formulas, and the majority of oil companies choose to do this to avoid the costs associated with testing. This, however, tends to commoditize the market. The same chemistry is being sold under many brand names. Most of the major oil companies do have their own proprietary formulas developed, tested and licensed. All of AMSOIL INC.'s lubricant formulas are unique and proprietary.
Why Some AMSOIL Synthetic Motor Oils Are API Licensed And Some Are Not
1. Full API licensing puts AMSOIL INC. in an inflexible position. Not only would we find it necessary to buy formula components from specific vendors and be at the mercy of their pricing, we would not be able to make any major improvements to the lubricant formulas for 2 to 3 years, without new testing and the associated costs. To solve this problem, the API must establish basestock interchange guidelines for synthetic basestocks just as they have for other basestocks, as well as develop interchange guidelines for other components too.
2. Full API licensing would impose strict phosphorous limitations on our motor oils. This limitation is the main reason most AMSOIL motor oils are not API licensed. AMSOIL INC. currently disagrees with this limitation and feels strongly that the reduced wear and longer oil and additive life achieved through higher levels of properly balanced phosphorous content is more important than the arbitrary API phosphorous limit that does not give any consideration to the NOACK volatility level of an oil. When chemistry is developed that will provide superior engine wear protection with reduced phosphorous levels, or Noack volatility considerations are put in place, then the phosphorous level will become a non-issue.
Warranties And API Licensed Motor Oils
Fortunately, the law does not allow manufacturers to "void your warranty" simply because of the brand of oil you use, the specifications it meets or the miles you drive between oil changes. To be specific, they cannot deny to fix your broken radio, faulty valve or cracked piston because you used an AMSOIL non-API licensed motor oil, or because you've gone more than 3000 miles since your last oil change. Denial of warranty coverage must be specifically due to an oil related failure. All courts of law will find against any manufacturer or dealership that tries these warranty shenanigans. If any automobile dealership insinuates that your warranty will be void if you use AMSOIL products or utilize extended drain intervals, let AMSOIL INC. know the name of the Dealership, the address, the owner's name and the name of the employee that made this statement.
Not to forget the COST FACTOR
The cost for running a test program for a single passenger car motor oil formulation is from $125,000 to $300,000, depending on if the formula passes the tests the first time through or requires multiple test runs or formula modifications to achieve a passing average. (That amount goes to $275,000 to $500,000 for a Heavy Duty Diesel licensing program on a specific formula.) Once that testing is complete and the formula has passed all of the minimum requirements, it can be licensed for $825 per year for non-members and $625 per year for members. There is also a small royalty fee per gallon sold for all gallons over one million. The length of time between new specifications is now approximately 2 to 3 years, which does not allow a great deal of time to recover testing costs.

Larry L,
(additional information)
How Does AMSOIL ensure their products "Meet Or Exceed The Minimum Specifications Of The Tests Required For API Licensing"?
First, AMSOIL INC. works closely with major additive companies to select the top performing, and usually most expensive, passenger car and heavy duty diesel motor oil additives. These additives have already passed all of the API licensing requirements in a petroleum or synthetic based formulation. Then we work with the additive company to maximize the amount of additive used and to boost the additive package in selected performance areas to achieve an optimum performing additive package for reduced wear and extended drain intervals. This is unlike the vast majority of companies who, because additives are expensive, use the minimum amount of the least expensive additives required to meet the minimum API requirements.
AMSOIL then utilizes a blend of synthetic basestocks with known performance characteristics as a replacement for the petroleum basestocks to optimize performance in areas of lubricity, volatility, viscosity index, oxidation and nitration resistance, pour points, flash points, deposit control, soot handling, emissions, etc. Amsoil also will utilize a highly shear stable V.I. improver to ensure viscosity retention throughout extended drain intervals. This replaces the inexpensive and less shear stable V.I. improver used in the API licensed petroleum formula. Amsoil does laboratory bench tests before running field tests to verify the superiority of the synthetic formula in actual use. Amsoil also continues to monitor the performance of the oil through close scrutiny of tens of thousands of oil analysis tests per year across a wide variety of vehicles all around North America and the World. AMSOIL has been collecting used synthetic oil samples from passenger cars since 1982. No other oil company has such a vast data base of the performance of synthetic lubricants over extended drain intervals.
AMSOIL INC.'s products and formulations outperform API licensed oils.
AMSOIL takes pride in never having conformed to industry norms or standards when those standards are contrary to peak performance. Amsoil introduced synthetics to the automotive world in 1972 with the first synthetic motor oil to exceed API performance specifications. At that time other manufacturers refused to recognize the superior performance of synthetic motor oils. Now, however, most companies sell synthetic lubricants, vehicles are factory filled with synthetic motor oils and gear lubes, and some manufacturers even offer extended warranties if you use synthetics.
AMSOIL has always offered extended drain intervals because the oil was capable of performing for extended drains, and it was the right thing to do for the consumer. Now the entire industry is moving in that direction. It was recently published that automotive manufacturers will be recommending extended drain intervals of up to 15,000 miles in the near future because that's what consumers want.
AMSOIL is a company of firsts. That doesn't happen by always conforming to industry norms and standards.
API licensing of lubricants is voluntary, and it ensures automobile manufacturers and consumers that the product meets a set of MINIMUM standards. Should these standards, in the future, be raised to a level consistent with AMSOIL's standards for motor oil performance, AMSOIL will consider licensing all oils. For those that feel pressured to use an API licensed product, we have them and encourage you to use them (XLT, XLF and PCO).
AMSOIL does offer better performing motor oils that are not API licensed for all of the reasons explained in this response. They provide our customers with alternatives to the commodity products typically available in the market today. If you want the convenience of extended drain intervals or the top performance from your vehicle, AMSOIL has taken time to engineer the very best money can buy.

Steve,
Thanks for the response.I have a few questions that I think are best answered by Amzoil in an open forum.
1.In your first post, you are correct about API and the levels of phos. used by Amzoil in it's formulations. I would like Amzoils response as to why API considers it too high? What are the drawbacks to too much phos.?
2. Why is there no boron in Amzoil? It is the best friction modifier/anti-wear agent available.
3.The XL7500 that meets API, what is the oil change frequency that Amzoil recommends?
In regards to warranty issues, it plainly states in the owners manual that the oil used must be approved by API. Anything else will void the warranty. Following your stated reasoning, I could put Mercon in the crankcase and it shouldn't void the warranty but I can assure you it will. I could even put kerosene in the gas tank and it shouldn't void the warranty. Sorry, but your statement is false.
For those not familiar with Amzoil let me state it is one of the best synthetic industrial lubricants on the market. Some of the analysis I've seen are remarkable. But here the glitch, these engines have Amzoils dual filtration system, oil pressure alarms after the filter system, and a rigorous maintenance schedule that includes oil analysis. You aren't going to find this on your Dakota. I also have a problem with Amzoil not stressing to users about having an oil analysis performed at scheduled intervals. How do you know the condition of the oil if you don't?
Sorry if this sounds confrontational Steve, but that's my way. I also want to thank you for being a sponsor. Without guys like you, we wouldn't have a forum to air things out.

daryl, unless you go and perform a wet and dry compression test to verify that the rings have seated this enitre disscussion becomes senseless as any answere will just be a guess!! Durability testing in the late 1960 showed that 95% or better of accelerated wear particles related to breakin were absent from the oil by 600-1000 miles. This means that break in has finished. Engines break in even sooner now. The ring gear in your vechile takes longer to break in then the engine. These studies were performed by the big three American companys as durability studies. The book on the subject was written by a gentleman named Sicorsky(sp)(same last name as the famous helicopter enginer) The title of the book is "Drive it Forever". I am not stateing opion I am stateing Imperical Facts generated by many, many studies!! The rings in your car tapered(to speed breakin), moly coated top ring(keep ring from mirco welding and is ultra hard and smooth), hardened SS oil control ring, cams are polished and ride agaist rollower rocker or cam followers that are polished or rolloerized(reduces friction and loadbearing). Valve guides do not break in the only parts that breakin past the intial 15-30 minutes of running are the Rings and valve seats. Valve guides really do not breakin. Owner manuals are cut and paste jobs based on older owners manuals and are put together by cut little laddys that know nothing about cars and make about $6 an hour. They owners manual is intended to give you the basic information to operate and maintain the vechile. It is not an all inclusive source of automotive knoldge. These same manuals often recomend non-synthetic 5W30 or 5W20 oils; that alone should tell you something about the usefullness of the manual. Not only am I speaking from 12 years of Tech. experince I am also a technical consultant and work in the automotive industry. I talk with suplier's, enginers, designers, tool and die operators and see ALL warranty and recall data just after it is generated. I actual see the durability studies and product concerns as the crop up. So the information is out their. Most of the information spewed by most are opion and are not rooted in scientific fact. One in a while a good article will apear in one of the car mags but not often. Just a few years back Turbo magazine had an article stateing that most breakin on a modern engine is done with in 15 minutes of driveing at HWY speeds. The exception that was noted in the article was piston expansion. It takes repeated heating and coolings in a confined space(see cylinder) to effectively stress relive the piston. If you put a piston in your house hold oven and heat them up and then let them cool the will distort to an egg shape. The round shape of the cylinder minimizes this. So while I was not trying to attack you in my origanal post I am really tired of all the voodoo surounding breakin and synthetics. The engines and differentials and transmission that are now filled with synthetic from GM at the factory have not changed in materials or design one bit to accomadate synthetic fluids. The one possable exception was the deletion of a drain plug on the 8.5 and 8.625 inch rear diff. They currently do not have any offical drain or refill recomendation. THe factory fill of synthetic is considered lubed for life. It only needs to be changed if it vecomes contaimanated or fails. Sorry for all the typo's trying to watch news about the opening of the air campaign in Iraq while I type!!!

This is why this forum is good, you're the first person that I've ever talked with about this break-in/synthetic issue, that has said it's ok to run syn right from go. You bring alot of hands on experience and some good common sense reguarding the factory themselves filling with syn right off of the production line. Both Royal Purple and Valvoline say to wait until first schedueled oil change before going to synthetic, whats your thoughts on the oil makers themselves saying to wait?
What about the assembly lube used in the production of the motor, does that have an impact on the recemendation to wait before going syn?

Larry L,
I think sandman addressed some of your questions.
I will attempt to address the others:
_____________________________________________
1) API standards limit the amount of phosphorus (P) in the oil (acutally a zinc phosphorus compound called ZDDP used as an antiwear agent). API certified oils both limit the P and limit the volatility. Amsoil has a very low level of volatility but prefers to add additional P in their formulation.
2) Why no boron? I believe Amsoil is comfortable with their current formulation and see no added benefits. They have an additive package that suits their needs, and they stick with it. Some companies use boron and some use moly and some use ____ and some use ____. Amsoil sees no need to use these products in their formulations or additives packages. Amsoil has 30 years of testing and oil analysis history to back their formulations. Some companies even use Teflon ... proven to be of no benefit ... but it is good for their marketing efforts.
3) XL7500...6 months or 7500 miles ... Under Normal Conditions. The lenght of service will depend to some degree on the quality of the air and oil filters you use.
___________________________________________
Larry ... Let me know what I did not answer to your satisfaction. P.S. I have always tried to make it a point that Amsoil extended drain oils should be changed according to Amsoils recommendations (not used blindly), and have been stressing to users about having an oil analysis performed at scheduled intervals if they are extending their drain intervals. Thank you for the kind comments towards sponsors.

Larry L,
To clarify my above comments:
The volatility of the oil is more of a factor in how phosphorus behaves. Amsoil has worked with Lubrizol to specifically reduce phosphorus volatility, and therefore Amsoil has more P. Phosphorus levels are a non-issue as far as I'm concerned.
2) After consulting with my manuals and Amsoil Corporate, I realized that most of the amsoil formulations do contain about 40-50 ppm of boron (borate ester), but it is not visibly advertised since other additives make up the bulk of the protection package.
3) Per Amsoil Corporate ... regarding Amsoil XL7500 - Drain interval is 7500 miles/6 months - even under severe service conditions (my earlier comments were on the cautious side). The XL-7500 is better than most of the on-the-shelf synthetics.

I'm giving it serious thought after 8 years of working on four wheelers to switching over to trucks.... That's a long story too....Anyways the oil change thing works for me and all seems well....One and only oil inspection/lab test that I had checked out the guy said your changing your oil too soon.....that was at 22,000 miles....I think now I have 22,450 miles.... i think my Dak will be around for a long time....
