Amsoil threads

[Don M]

Gary,



The API program is a cooperative effort between the oil industry and vehicle and engine manufacturers Ford, General Motors, and DaimlerChrysler; the Japan Automobile Manufacturers Association; and the Engine Manufacturers Association. Performance requirements, test methods, and limits are cooperatively established by vehicle and engine manufacturers, technical societies like the Society of Automotive Engineers (SAE) and the American Society for Testing and Materials (ASTM) and industry associations like the American Chemistry Council and API.



API's Engine Oil program is backed by an ongoing monitoring and enforcement program to ensure licensees adhere to industry technical specifications. Additionally, the program ensures that the API-registered symbols are properly displayed and convey accurate information to consumers. Currently, more than 500 marketers in 48 countries are using the symbols on more than 5,000 products.



A quick read of the MACK website (which uses tons of Cummins engines) will show us that they actually test oils for performance and make a "list" of approved lubricants. Amsoil is not on the "list" with their fully synthetic oils. They do have a blended oil that did pass the lesser test from MACK. This oil does not qualify for any of the extended drain programs in place from MACK and is the lowest of and easier tests to pass.



Yes all the engine manufacturers have oil testing in place and some of them name actual names of approved marketers and brand or type that is acceptable. Detroit Diesel states in their lubricating oils guideline to "beware of marketers that claim to meet API specs". Beware? What the heck is that? Ok, I will "beware" of Amsoil now. How sad.

I personally saw an increrase of 5-7 MPG in my 95 CTD when I switched THE WHOLE TRUCK over to Amsoil at about 30,000 miles.

That's a typo, right? If I could get 5-7mpg improvement I'd be switching over to Amsoil tomorrow. I did see a 1mpg improvement when I switched my ex-girlfriends car (little 4 door dodge thingy) over to Mobil1. I really have a hard time believing a 5-7mpg improvement for most folks.

Sorry TxDieselKid,



I was typing and didn't see your plea for mercy in time.

You remind me of the movie "Clockwork Orange. " The guy started out liking sex and violence - until they clamped his eyes open and make him watch it 24 hours a day. By the end, he couldn't stand it any more.



Think maybe we're getting that way about oil discussions?

I remind you of this guy? I never liked oil threads to begin with, and these have been some of the funnest I think I have seen. But I think all but 8 of us are so sick of oil, that I don't even want to change mine.



Dan, at this rate, you will be the cause of having another thread closed. Remember who started it, darn pot-stirer!

Typo

No, 5-7 MPG is NOT a typo. When I first picked my truck up in January of 96, I immediatly drove to West Virginia (from jersey) on the trip, and for the next few months I kept records(by hand) of my mileage. It ranged from 11mpg while towing a dual axle dual wheel tilt bed trailer with a John Deere 410B 4x4 Backhoe on it from jersey to the Poconos empty and the Poconos home loaded. I haven't a clue what my GVW was but the trailer is rated for 21 tons... I was WAYYYY overloaded. To a best of 15mpg basically empty to a ski trip in the Poconos. These were recorded in the first year of the trucks life. I heard about Amsoil from watching Snowmobile Racing on T. V. I looked into it a little and decided to try it. At 34,000 miles I ordered an Oil Filter, Air Filter, Series 3000 5W-30 Motor Oil, Series 2000 Gear Lube, Universal ATF for the transfer case, and Synthetic Grease . (the grease #'s escape me as I've run out... it's quite popular with my uncle and his Mack... have to order more) The lowest I've recorded since the change was 16 mpg around town... very next tank of fuel after change over. The highest I've recorded since was 22mpg on a trip 2 weeks ago to Big Boulder Ski resort in the Poconos. I usually get between 18-20 mpg as a daily driver... depending how much foot I put into #5 TST plate!!!! I realize that as a Cummins wears it attains better fuel mileage ... so if you really want to nit pick I did only see a gain of 1 mpg from my best without Amsoil to the VERY next tank with Amsoil ... . but that's not how I see it.

BTW... had I known everything Don has explained lately, I don't think I ever would have tried Amsoil, and can understand all the reservations and catfights herein. What I now want to know from the resident Amsoil experts is why doesn't Amsoil get tested. I mean why should everyone live by one standard and Amsoil gets to live by another? If you think your product is good enough or it EXCEEDS everyone else... prove it!!!! I for one think it does exceed alot of others... here I am defending Amsoil, and when I go to find the data to back it up, all I find are a bunch of

sales-pitch-used car-salesman promises!!!!NO REAL DATA!!!! Hey I am starting to see why this is PI**ING soo many guys off!!!! Yea, I think I'm gonna go out right now and drain all the Amsoil out of my truck!!!!Until they come up with some real data, Oh wait, I forgot... I like Amsoil repeat after me ... I like Amsoil... I like Amsoil... .
