Engine/Transmission (1998.5 - 2002) Slick 50 Additive

[FISHIDAHO]

My buddy just purchased a 2002 eth, and said that he is going to run slick 50 in his rear end, transmission and diff. I told him to be careful doing anything until I ran this past the TDR members. Is slick 50 a good thing, or a bad thing. By the way, my buddy runs a school district bus garage, where all the school buses have the cummins diesel engine. His mechanics do all the maintenance on the cummins, and they have a few buses that have over 250,000 mile on them. He has ordered buses in the past with the power stroke and said 'never again!'. Cummins is all he will be using from now on. Anyway, didn't mean to ramble on. Thanks!

I had a Toyota 4x4 p/u it used no oil. I put snakeoil,I mean Slick 50 in the engine and it started using oil. A mechanic told me with the Teflon in the oil(from S-50) the tolorences change. I will never use S-50 again. Nor will I recommend it to anyone ever!!!



You have an engine rated for 300,000 miles,don`t shorten the lifespan.

I would never use additives with oil, either use straight conventional oil or Synthetic. As mentioned above, using conventional oil and 4k miles oil changes you can easily see 200,000 miles or more, dont mess with some gimmick additive, its not worth it.

I know in the engine it is bad news. Teflon is great when it stays in suspension, does not clump, does not melt, and is not exposed to high temperatures. When exposed to high temperatures ( ie. top ring ) it can break the flourine free from the teflon. The resulting hydroflouric acid must then be nuetralized by base additives in the oil. In certain instances teflon particles can form clumps and clog oil passages. This has in the past destroyed engines. ( sorry I do not have VIN numbers- search some threads) Slick 50 started out selling "snake oil" and has tried to gain respectability. If in doubt call the company. Ask them if they will warrantee your motor for lubrication failures from thier product. Not a new bottle of slick 50 but a new or reman engine. If they put it in writing I would not hesitate to use it (not). As far as the other gearcases there are better EP (extrememe pressure )additives with less negative side effects for transmissions and gear boxes. And they are part of quality oils made for the application. OBTW the manufactuere of teflon ( DOW ???)has stated publicly that powdered PTFE is not intended for internal combustion use. And would not be resposible for the damage. I am not in any way an amsoil believer. But if he is insistent on expensive oil than he should use amsoil. I do not believe thier claims but I am sure it will not cause damage like slick 50 products. Cummins and other companies do failure analysis of the warrrantee parts. Per a 1999 plant tour in indiana, if lubrication failure is found as a cause, and aftermarket additives are found in the oil- no warrantee. If it is lubrication failure and it is normal oil they have a problem with that engine.

Slick 50 , Duralube , Prolong , Motor up... ... Its all crap , a waste of money and hype in fact it is now illegal for these companies to make these ridicules claims for there products on TV. I agree with Jsmith that in the long run you will do more damage than good . I to have used slick 50 in not one vehicle but two , both started burning oil prematurely. Prolong did a infomercial on the tube where they had two ladies driving two separate cars through LA with no oil and treated with Prolong and the cars ran for more than two hours , an independent lab did the same test and both engines seized up in under 2 minutes. . SOLID . Stick with a good quality synthetic you'll never need any additives .

PZicha nailed it right on the money. Check out the following for more details on Slick 50:

I used to be very interested in Splitfire spark plugs for my gassers until I read that the FTC nailed them as well because their product was crap.
