Synthetic Auto Transmission Fluid

[DMcPherson]

wow interesting. I have written articles on oil issues like these. and first the price difference is easily overcome with drain interval, actually costing less over 100k miles than petrolium based lubes. then the life of parts. if it doesnt break or wear your not paying to replace it. as far as I see it is much much cheaper. heat is what kills, not from the heat directy but from oil breaking down from the heat. "real" synthetic does not break down from heat.

the other comment that killed me was about mobil 1 which in my OPINION is the worst oil produced, manufacturers reccomend it because mobil pays them to. I kneew a mobil rep and he wouldent let us put it in his truck. I have seen race cars iwth 20w-50 come off the track and have 0 ol pressure. and they say, its how mobil runs. and it doesnt seem to bother them. scares me. mobil is only blended anyway, and dont let the bottle fool you. their"full" synthetic is still petrolium based which is bad. petrolium breaks down from heat and the byproducts of combustion, ester oil does not. i. e. amsoil and thelike. Ill stop now. just my . 02$

Interesting thread guys. I can't believe I read the whole thing in one sitting, but I did. I wish I could say I wasn't still confused. I just recently changed all my fluids at 18,000 and I went with what Dodge recommended in the engine, axles, and the transmission.



I was thinking about switching my engine oil next go-round and using the Valvoline Blue that Cummins recommends. Now I'm having second thoughts. I might use the Amsoil. I'm not real concerned about if Brand X costs $4 a quart and Brand Z costs $8 a quart if I can get longer life out of Brand Z. I don't care if Amsoil and their dealers make some money either. Nobody should have to work for free (except the worthless politicians :-laf ).

O. K. , Now the next round of questions.

Which is better amsoil or redline in the following products and why?



1. Amsoil MTF VS. redline MTL



2. amsoil Synthetic universal ATF VS. redline C+ ATF



3. amsoil severe gear 75w-90 VS. redline 75w-90 gear oil



4. amsoil severe gear 75w-140 VS. redline 80w-140 gear oil



AS a side note I can get the same amount of products from both and the cost.



amsoil = $162. 63 This includes the $10. 00 perferred customer payment.

redline = $128. 72

Both include shipping to my door.



Is amsoil worth the extra cost over redline?



Please no subjective information. Please no bashing. I want actual pros and cons.



Thanks.

Redline is a top flight company, if you are saving that much money go with the Redline fluids, don't be afraid to look into the Royal Purple brands as well, you can find them at HTTP://www.RPMOIL.COM



I am turning 15,000 and am ready to switch the engine over to synthetic, I am going with the Royal Purple 15w-40 CI-4 rated engine oil, for the rear end I changed it at 7,500 and used Syn-lube it was very expensive and rated GL-5, I am changing it again at 15,000 and going to the Royal Purple gear lube rated GL-5, and I am changing the automatic transmission fluid at 15,000 as well, I am going with the Redline ATF C+.



I am changing the rear end and transmission at 15,000 because I am installing PML transmission pan and rear end cover for the added fluid they hold.



I will follow the Dodge/Cummins 15,000 mile oil change from now on, Dodge/AAM calls for the rear end to be serviced every 15,000 as well, the Automatic transmission will be serviced every 30,000 from this point forward as per the Dodge service schedule in the manual.

It seems Amsoil has paid out on their warranty due to oil related failure before, and if I read the thread right Amsoil has paid out on multiple claims, it also looks like the claim-it is a Amsoil dealer as well in this thread.



http://groups.google.com/group/alt....42c1efd92cec757?sa=X&oi=groupsr&start=0&num=2



The positive is Amsoil paid out on the oil related failure from their product.



The negative is Amsoil product failed to protect the engine as advertised resulting in engine failure.



Follow the manufactures oil change schedule, they designed and built the engines, I think they know what their engines require as the above link proves.

That Camry engine as well as 2. 7 Chrysler and a Mercedes and some others are KNOWN sludge monsters. I have found a site devoted to these issues in the past. Poor head design with EXTREMLY high heat and pcv issues. Took Toyota and some others a long time to admit a design fault and step up to the plate and handle the repairs. The Toyota in question went 27k and a failure. Others on dino only went to high teens with 5k to 7500 mile oil changes and totaly sludged up and failing.

Amsoil sued and settles law suit over faulty Amsoil Gear Oil that damaged gear boxes resulting in recall by manufacturer.

[DPKetchum]

Ok whats the jest of the lawsuit. Which gear oil in what vehicles and what transpired? read a lot of legal and figures but couldn't find the deails of what,when where and why so much.

the difference in the redline and the amsoil are simple the red line is formulated with ester base stocks, which is good for raceing,but it flows only to -20or30 degrees it is not very good for cold weather but performs well in the extream heat +300* the amsoil is the first to use and incorperate the PAO synthetics base stock, which allows it to flow at -60 and be good for over +500* thats accually where we test all of our oils for noack votality!!! this is the best base stock for the best overall performance bar none. there are other differences but overall i like redline and would use it if i had to but one thing i would never use-even though i have sold it is royal purple, and lucas. those oils have lost more motors consecuatively than any motor oil i can think of, and i have witnessed both happen in person!! but to each his own. thanks :-laf

now the TRUTH behind this is that the customer added things to the oil, which amsoil DOES NOT RECOMEND, and those additives worked against the oil, thats why you should not mix different types of oil. remember these are chemicles you are toying with. not a lubrication break down but a additive break down!! yes amsoil payed out any way!! even though it was not amsoils fault. !!!. thanks :-laf

 

[Ken55]

i wish i could get atf+4 @ 4. 00 qt. last time @ dealer ,2 years ago it was 8. 00a qt.

Ditto on that!! Just changed the fluid in mine and the dealer was just under $8. 00qt. In my neck of the woods they are the only source for the stuff. I did find it in Chicago at Murrays Auto Parts for $5. 00+ though.

Well, with the powertrain warranty in mind I pay for the MOPAR ATF4+. I am also getting tired of changing the ATF myself outside in the winter... Using the MOPAR and having the dealer change the fluid at the recommended interval (or sooner) I don't have to worry about Chrysler denying what could be a $$$ repair.



FWIW I don't let the dealer use the flush machine that they mildly push. They change out the filter and clean the pan. I just did that recently and while they were under there they adjusted the bands too. One can't do that via a flush machine.

You sure do make a lot of statements that you have no data to back up what you claim, Amsoil would have never paid off if their oil was not at fault.



Please provide the data where this person added anything other then pure Amsoil.



Here is a link to Redline for their data on their oil:

No wonder the guy from DTT jumped all over you the other day.

Another factual error on your part, here is the data from Redlines web site:



http://www.redlineoil.com/pdf/4.pdf



By the way it flows down to 49 degrees.

As was mentioned earlier, this is a known problem with the engine in question. As a matter of fact, Amsoil issued a TSB on this. I suppose the owner was never made aware of this!

Still blows the myth out of the water that Amsoil has never paid out on their warranty, they clearly paid out on it, nor does it change the fact that the Amsoil gear lube failed and Amsoil settled out of court in that case.



Amsoil just like any other oil is prone to failure from time to time.

that statement is true, no oil company is prone to failure--thats why we offer a warranty, does any one else? and if you look at redlines web site, they have a pore point of -45c and -49f are impossible, the difference between celsius and farenhight is 32* and i never said any thing bad about red line oil, i like it. also me and DTT were arguing over something different than you are implieing!!! everything is now fine. you obviously have nothing to do but search the internet and bash amsoil. sometimes you need to look out side the box!! like i said before amsoil is not for every one!! the original question was about warranty using synthetic oil not a battle between redline and amsoil. let it go dude. thank you for the conversation .

 

[RMalone]

Good Lord, seven pages of arguments debating whether amsoil is junk or not. This is the 10th similar thread I have read in the year I have been a TDR member. Everybody is splitting hairs, nearly all of the certified Dino and premium synthetic lubricatants will work just fine. Way too many people have used the cheapest certified lubes and run tons of miles for them to be junk.



I use mobile 5-40 synth, mainly because it helps BIG TIME with cold starts, better than delvac 15-40 dino and 15-40 amsoil, no competition. I run 10k with a filter change at 5k. Perhaps I am going to grenade my motor at 100k (56k now) but I doubt it.



Why change the rear end lube every 15K, unless you tow real heavy real often?? Most passenger vehicles never see a rear end fluid swap. And I almost never hear of someone blowing up the rear end, maybe a muscle car with a little tiny grapefruit for a rear end, but not our 11. 5 AA pumpkins.



With transmission's my DTT guy uses mercon III in both 48re and 47re, my truck has 30k on a load of mercon III with zero problems. I am about to change and I will put ATF+4 or amsoil in the tub just because I want to see if the sucker feels any different. As a disclaimer I don't tow much.



As far as warranties I have more than enough mods to pretty much kiss 'em goodbye. Besides I wouldn't dream of letting a chrysler tech touch my DTT or sps66 or injectors.



If you are running a stock truck and concerned about your warranty then follow DCX instuctions to the letter. If you have your share of mods put whaterver you feel comfortable with in the truck. And stop ragging on each other.

 

[Oil Burner1]

I am running Valvoline full synthetic ATF+4 in my 96. It cost me $4/quart at shucks auto supply. Noticably smoother shifts and my temp gauge runs a couple degrees cooler.



I ran Amsoil in my previous vehicle a 97 chev tahoe with a 4L60E towing my 4500# ski boat. Before switching to Amsoil I had never gotten a trans temp light. Afterwards I got a few followed by hard shifting. Everything was in order as far as filter/fluid level/cooler function ect. , I checked as did my mechanic. It could have been something else internal in the trans so I can't say it was for sure the trans fluid. Regardless I will run other brands from now on.

 

[dieseldude]

amsoil is designed to reduce temps. why would it increase yours? when I put it in my truck I noticed a decrease.
