Just a quick note. I read all e-mails posted,and I drive a 1995 GMC 1500 with 350/auto,and air cond. I switched to Royal Purple at 85,000 with no leaks after 9,000 miles. Had used Mobil 1 since 66,000 up to the above 85,000 change. The RoyalPurple engineer has helped a lot and tested my oil once at 7,900 oil change. Now I will change filter at 4,000 and retest at 8,000 per his recomendation. He said I should be able to go to 6,000 filter change and 12,000 mile oil change. WE WILL LET THE FACTS DECIDE. Although I feel that a motor (gasoline) is a motor, (excludeing significant metalurical diff. etc)driving styles, atmospheric conditions,temperatures(motor and atmopheric) and other variables do have a impact on oil life. The only true way really know is to test the oil! Almost all synthetic oils are better than convetional, but the issue to me is am I going for keeping a vehicle many miles or not, am I looking for longer oil change intervals. If you want long change intervals and long engine life, you have to choose synthtic.
On oil filters, of all the things that you really should do,filter change is a must. As I understand it as the differential pressure across the filter element will increase due to contamination. The filter bypass spring or the engine built in bypass will open and allow un filtered oil to run through your system. Most bearing clearances are in the range of .001 to .003. If your filter is working most have a micron efficiency of 20 which equates to .0008(almost.001)If your cleance is .003 your OK if it is .001 your already in trouble because your .001 is actually .0005 per side of the shaft or other round part. The 20 micron(.0008)is bigger than the clearance and one must rely on the oil to protect the soft bearing surfaces. I think you get the Idea that your filter other than no oil is critical to engine life. Change filters, they are the weak link in engine protection if they are not maintained.!!!!

"Best" or "Favorite" Performance Motor Oil???
First, If you wanted opinions, you should have used the word "favorite" instead of "best". Best implies logic, but favorite implies emotions, which are illogical and opinionated.
By what criteria? Price, anecdotal or actual performance, additive package, drain intervals?
--------------------------------------------------
Second, I am going to recommend 100% Synthetic Oils, and if you have to ask why then you should read information on the benefits of synthetics on my website, or from some of my posts on this website.
--------------------------------------------------
Third, "100% True Synthetic" is Group IV/Group V and "Hydrocracked (not 100%) Synthetic" is Group III (still better than straight dino). A "true 100% synthetic oil" uses either the Group IV or Group V basestock, or a mixture of the two. As a matter of fact, I don't think any of the synthetics use just one, they mix them both. Group IV is PAOs (Polyalfaolefins) while Group V is the esters.
--------------------------------------------------
Fourth, there are other 100% synthetics than the one's I will mention below, but not as readily available, and i mention these three because they are the "favorite" 100% true synthetics on this website:
--------------------------------------------------
Redline is an excellent synthetic oil, but VERY pricey (currently about $10 or more per quart), and they offer no Preferred Customer Program whereby customers can receive approximately 20% off retail pricing (Amsoil does). Redline has an excellent additive package.
Of course I am particular to Amsoil. Amsoil has a 30 year history, mountains of data to back up their claims, an excellent additive package, and offers extended drain intervals. Amsoil is currently priced below Mobil1 as of now, so it has an excellent price/performance ratio.
Mobil1 is good for an "on-the-shelf" synthetic oil, but it could be better. My brother-in-law owns two dealerships in Europe and the European Formulation for Mobil1 there is much better than the U.S. Mobil1 Formulation. It is a weaker formulation in the U.S. to compete price-wise with the other "on-the-shelf" oils.
--------------------------------------------------
Others will post after me, since this is a hot topic (third only to politics and religion) ...
Last but not least ... Don't forget to use the best filtration ... Dirt is Enemy # 1.

Royal Purple..
A friend of mine races a 69 hemi cuda (NHRA). He also owns a speed shop with dyno. He dynoed his hemi before and after using Royal purple. He gained about 20hp using Royal Purple. More HP means less friction. He now uses Royal purple in everything.

A 20hp increase in a hemi cuda is possible. I've seen 25hp improvements with a Viper. My daily driver V8 Dakota (and any average vehicle) will experience almost no improvements in hp. I tried RP and got 4hp increase, which is so small it can not be attributed to the RP oil. It all depends on the vehicle tested. Per my mechanic, RP is for the track or for true street racers, and not daily drivers.

"Best 'Performance' Motor Oil ???"
Increased performance is a subjective benefit, but it can be actually measured in numerous ways:
Better cold weather starting due to lower pour points.
Cooler running at high temperatures and under severe conditions. This requires measurement of operating temperatures when using petroleum lubricants and then synthetic lubricants in the same equipment under identical conditions. A controlled test is needed to demonstrate this, and it has been proven by Amsoil and others when testing synthetics in general. Most users are able to actually see the difference in their engine and transmission operating temperatures when running under similar conditions.
Less component wear, as AMSOIL and others have demonstrated that synthetics offer as compared to petroleum. Usually this is only apparent to the end user when comparing oil analysis reports and comparing the wear metals in parts per million per mile when using synthetics vs. petroleum in the same vehicle. Certainly after many miles of use there would be a visual difference in wear in a controlled comparison of two similar engines, transmissions, or differentials.
More horsepower as demonstrated on dynameter tests comparing AMSOIL products with petroleum oils and other synthetics.
Reduced oil consumption as experienced by nearly everyone using synthetics due to lower volatility.
Reduced emissions, also due to lower volatility, but not generally noticeable by the typical consumer. And there are others. Most of these performance benefits require close scrutiny by a consumer, or a controlled test to demonstrate quantitatively.
Fuel economy can also be very difficult for the consumer to accurately gauge. Once again, it has been proven by AMSOIL INC. through use of industry accepted fuel economy tests, field demonstrations and as witnessed by most of our customers. In an extremely elaborate and expensive test run by an independent laboratory, which we have documented in a brochure, we showed an 8.2% fuel economy increase in Class 8 over the road trucks.

This post is to CLEAR THE AIR regarding Extended Drains using Synthetic Motor Oil. The question has been brought up on other threads. I want to "clear the air". Thank You!
--------------------------------------------------
***** READ THIS PLEASE EVERYONE *****
The ability to extend drains to the 25,000 mile / 1 year that is on the back of the Amsoil Motor Oil bottle is NOT an absolute! (Even Redline recently stated their oils were CAPABLE of 25k miles - so it is no joke - Extended Drains are a FACT, if you use the proper oil, filter, and follow directions). One must realize that is for non-severe service (highway miles where you have stable operating conditions), and only after you have established ... "through oil analysis" that your particular vehicle can "go the distance".
WHAT AMSOIL SAYS:
** PLEASE READ AMSOIL RECOMMENDATIONS: Under a combination of city and highway circumstances, AMSOIL recommends up to 2 or 3 times longer, it means up to 2 or 3 times the equipment manufacturer's recommendation (If your owners manual states 3k miles , then you can change at 9k, and if your owners manual states 5k then 12-15k changes would be alright based on driving habits ... the harder you drive, the sooner the change). Proper filtration is also very important. AMSOIL SDF Oil Filters must be changed at least every 6 months regardless of miles driven.

Well fellas I like conventional Castrol and I change my oil every 3,000 miles. I can still sleep at night. Yet, if I raced my vehicle I would probably buy synthetic and it would still be Castrol. By the way, I work for a major phone company not oil company.

Interesting thread and as usual, most folks are confused about oils. Rdak2001 has a decent grip on it but I wonder if he knows the exacts of why he is kinda right? Oils are different. Different basestocks, different grades of basestock,different additive packages, different weights, flashpoints, Viscosity Indexs, and the list goes on. In a race engine, the Redline would be the oil of choice because it contains a bunch of moly. Race engines run mostly at the boundary lubrication point. This is where moly is the additive of choice. For a daily driver, if you need or want a synthetic, Amzoil is the best hands down. Most people though, don't need a synthetic and assume that a synthetic will give them longer engine life- not necessarily so. For normal driving, there will be no additional life in the engine. Actually, we see more wear metals with ALL synthetics than premium dinos. While the wear metals are 2-3 and sometimes 4 times higher than a dino, to keep it in perspective, this is in parts per million. The point is synthetics are not a cure all. They have advantages and it mainly is in thermal breakdown. For the normal driver, he won't see this condition. The statement that synthetics are best is wrong. Synthetics are not for every engine. Take the Chevy 3.8 engine as an example. If you want to see the wear metals go off the scales, put a synthetic in it, any synthetic. Want to hear an engine knock, run it in the 3.8 for about 40,000 miles. It has to do with the engine design, not the oil, but the engine demands dino oils. As I stated, sythetics are not for every engine or for everybody. The best oil depends on the engine it is being used in.
