 Subject: is synthetic oil worth it

Message:
I have an 87 v6 4x4. I was wondering if it is really worth it to switch to synthetic oil. My truck was designed to work with regular oil, and thats what its been getting. Should i stay with regular or move to synthetic. My oil change is about 1500 out and my differentials are due. I know if the amsoil guy reads this hes gonna post that synthetic is better but hes payed to say that. I just want a good honest unbiased opinion. If it is better what kind should i use. I'm currently using mopar sae 30, and atf +3 in the trans. Thanks

I have no opinion on gear and tranny syn's but I can tell you that with manual temp gauges I do see a drop in oil temps using Mobil 1.
After I saw as much as 10 dgrees cooler in dead of summer I never used anything else afterwards.
Afterall....heat is an engines enimy.

I'm with FazDak. It's worth it UNLESS, you are leaking oil already. Synthetic oil will soften seals and clean sludge from your engine. Leaks will get worse. At a Minimum use a Quality synthetic blend with a GOOD filter.
NEVER NEVER NEVER add any type of "Engine Sealant" to compensate for the Oil leakage.
I Only Mobil 1 Full Synthetic but after reading different manufacture tests, I'm going to try Castrol Syntec again.
Just my 2c

I just started using synthetic, thanks to this site, and am pleased. I put Redline MTL in my car's 5spd and now it seems to pull a little smoother and it definately shifts much smoother. Maybe Redline is awesome, or its because there was nasty gear oil in there. I dunno why someone put gear oil in my car, but it was before I bought it.
I changed my tranny fluid and filter about 10k miles ago in my truck w/factory fluids. The other day I put amsoil ATF in my 92 dakota (138k miles) and adjusted the bands. It shifts near perfect(almost exactly how I want it to, isnt funny how you can make your dakota contour to you!). I love it. It could have been me adjusting the bands, or the amsoil atf could be that good, I dunno. Tomorrow Ill put in the amsoil 80w-90 I just bought and see if it gets even better.
I cannot say for sure that amsoil or redline synthetics are better, but there is a very good chance they are. If I notice a good difference when I change the gear oil, then I'll be a believer, and probably buy amsoil oil, filters, and flush for both my car and truck.

A book could be written on the benefits of Synthetic Lubricants vs. Petroleum (dino).
Switching to Synthetic Lubricants is one of the least expensive and smartest investments you will ever make to insure that your vehicle (or any motorized equipment) will run the longest with the least amount of maintenance and the highest fuel efficiency. Lubricating oils are the lifeblood of mechanical equipment, and are the single most determining factor in how long your equipment will last, perform, and what the costs of maintaining that equipment will be.
--------------------------------------------------
Since Dakota Owners are "Performance" Driven,' let's discuss performance:
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 us 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 (and others) that through use of industry accepted fuel economy tests, field demonstrations and as witnessed by most of our customers, switching to synthetics should show improved MPG.
==================================================
I sometimes hear "Synthetic oils contain detergents that can make the oil seals leak in older cars or trucks." Is this really an issue? How old would a vehicle have to be to not use synthetics?
Synthetic lubricants do have an inherent detergency that cleans and removes conventional motor oil deposits left over in an engine. However, motor oils are designed to help swell seals slightly to prevent leakage. The only time you would observe seal leakage is if the seals are already damaged or showing signs of leakage around them. As long as the vehicle has been well maintained, and in good mechanical condition, it can be switched to a synthetic lubricant at any mileage.
Next, let me explain the story behind leaking gaskets/seals. AMSOIL lubricants are all tested for seal compatibility with all the seal materials in use with industry accepted testing methods. AMSOIL Products will not damage seals or be more prone to leaking than petroleum products when used in vehicles with undamaged seals. Unfortunately, high mileage vehicles and equipment that have been using petroleum lubricants for long periods of time face the risk that sludge and deposits have built up in the engine and created a false seal, and the seal itself has dried out and cracked or shrunk. Lubricants help condition seals, keeping them supple and slightly swelled to insure a proper seal with no leaks. When covered with sludge or deposits, the seal will deteriorate. Now you start using AMSOIL motor oil with it’s high quality additive package and natural detergency, and you start to clean up the engine. The false seal is cleaned away, and if the seal itself has become cracked or damaged, a leak will develop. The same thing occurs in transmissions and differentials. Because of this, many people think that synthetic oil is more prone to leaking, when all it really is doing is revealing the problem that petroleum oil deposits had created and kept hidden. Once the damaged seals are properly replaced, keep using the synthetic oil and they won’t leak again.
--------------------------------------------------
Now for a word from our Sponsor (heh heh) ...
Where can you find Amsoil?
Unlike mass marketed petroleum products which are bulk manufactured to provide the minimum lubrication at the cheapest price, AMSOIL's line of synthetic products are individually crafted to provide the most durable protection in the most extreme temperature and load conditions you may encounter. The AMSOIL durability also shows up in product longevity, since AMSOIL synthetic oils and fluids last upwards of 8 times longer than conventional petroleum products. The strength of synthetic lubrication is the ability to eliminate the organic elements that cause conventional petroleum oils to breakdown and lose efficiency. Further, synthetic lubricants can be tailored with specific additives to function at a MUCH higher efficiency in extreme conditions, allowing your oils to function immediately in cold start conditions or to continue to provide stable protection in extremely hot conditions that cause petroleum oils to fail at potentially catastrophic results to your machinery.
The advantages of AMSOIL are hardly limited to extreme conditions, but rather from their strength in day-to-day use. At the core of AMSOIL's synthetic lubricants is the ability to provide superior lubrication. That means engines and machinery operate more efficiently, with less friction. Less friction means less heat produced and less wear and tear on mechanical parts, which allow engines and machinery to have much longer life spans. The increase in operating efficiency also means an increase in power and fuel efficiency, since your equipment is not fighting against itself and friction.
AMSOIL is not designed to be put on sale at the grocery store for the cheapest price possible. An AMSOIL customer makes an informed decision to choose AMSOIL to safeguard the enormous investment they make in their vehicles, fleets, machinery or heavy equipment, and to insure that their equipment will last the longest with the minimum amount of maintenance.

I have 138k on my truck and 159k on my car and I want to change to amsoil. As far as I know, dino oil has been in both for their whole life. If I did go with amsoil, maybe it'll leak, maybe it won't. If it does (because the synthetic cleaned the false seal", could I switch back to dino and make another false seal???? Or would it leak badly for a long time until more "sludge" could build back up. I want synthetic, but dont want to replace anything. What does everyone think???

It would take time for the sludge to build back up and fill the worn gap.
Steve said we need a "controlled environment" test. Here is my Un-Controlled test.....
I was in Germany & when I started my Ford Ranger in the morning (10-25 degrees) it would sound like the battery was almost dead trying to get it going and then when it did start it would rattle/shake & knock first couple seconds until the oil started flowing. Switched to Synthetic and never happened at all! Fired up like a warm engine without all the internal destruction until it got lubricated.
Just my personal experience..

Shank,
Thanks for the comment.
Yes, Synthetics Provide Better Low Temperature Protection
For Example: AMSOIL 5W-30 remains fluid at temperatures as frigid as -60°F (-51°C). It permits easy engine cranking for fast starts and in sub-zero temperatures flows to all engine parts much faster than petroleum motor oils. The exceptional cold temperature properties of AMSOIL 5W-30 provide immediate cold start lubrication, greatly reducing engine wear and prolonging engine life.

I asked a respected petroleum engineer (my Uncle) why auto manufacturers don’t specify synthetic oils for use in their products. His response was both candid and revealing: “Auto manufacturers must, by necessity, stick to the ‘generic’ SAE standards in recommending oil grades and viscosities…and synthetics are way ahead of SAE standards. The top SAE motor oil classifications (SD, SE, SF, etc.), rather than being benchmarks of excellence, are merely ‘highest common denominators’. The highest SAE rating (currently ‘SL’ in 2003), for example, is determined not for the state-of-the-art performance of the better synthetics, but rather for the best possible performance of petroleum oils currently achievable by a majority of petroleum oil producers (emphasis ours). It is not surprising then that synthetics pass these qualifications effortlessly. What is needed is an entirely additional set of SAE standards, for synthetics. Such a grading system would, in effect, start where current SAE (petroleum-oriented) specs leave off. If such a premium grading system were adopted by the Society (SAE), then you’d see the automakers universally recommending lighter oils in grades and with recommended drain intervals completely beyond the reach of petroleum products…”

It speaks volumes on the superiority of synthetics over dino. It basically states that the SL rating by the SAE is for dinos only and that synthetics are way beyond such rating.
