Schaffers!!!!! Find a dealer and see the demo, you will never belive how pure friction can be defeated by a quality oil. As for shell rotella T, I wouldnt run that in my 90 ford escort GT(its a real gem).

I wish i could remember the book of independent studies done on oils that break them down based on contents such as ash and others.(anyone help me out if you know) The studies rated each oil with a base number. If the base number was 10, you could run at 100% of normal intervals such as 10000mi on heavy on road diesel, or 3000mi in your family cruiser. Lets say your base # was a 8.3, you were only to run on 83% of recomended interval(8300 mi). Anyway the rotella T was rated i belive in the 7 somethings. Now i am a touch bias to the schaffer oil since i saw the dealers demo on it( ive seen the ams oil and others but this was simple friction(a wheel on an electric motor with an amp meter and a timken bearing roller on a lever that pushed aginst the wheel)). Ask yourself this, Is mack in the business of making oil to get rich? No. The build a damn fine truck with great components and they want them to last as long as the name Mack has. So when they design an oil to run in there engines, it is formulated to ensure longevity of its components. If your mack engine need to be rebuilt at a rediculusly low hour/milage, are you going to blame the engine or your oil??? What im saying is, Mack has a great name, and they want to uphold it, so mack makes oil to help uphold there name. And for what you may save by running a cheaper oil, will be lost with the shorter change intervals( if you follow the base numbers) and filters.

I WILL TRY TO FIND THE NAME OF THAT STUDY WITH THE OILS IN IT.

I KNEW I WOULD FIND IT...... If you want the info that the manufacturers have, you must have the data that they, the engine makers, use. Now I have had a look at this book, and i find it to be the best. I find an engine manufacturer and this book gives you the minimum requirements that they need. Then they show which oils match meet or exceed OR lacks the amout needed. Its simple. If you have a _____ engine, It give check marks on which oils meet its needs. The base number is given for each oil also and as in my other post, it tells me if it is a real bargan to buy cheaper oil and more filters, or change less and spend more..

ENGINE MANUFACTURERS ASSOCIATION

ENGINE FLUID DATA BOOK

ITS $110 BUCKS BUT WHEN I USED IT AT SCHOOL, IT OPENED MY EYES TO THE TRUTH ABOUT OILS. Everyone in my class thought shell rotella t was great oil. Even i was suprised to see that it meets very few major engine manufacturers needs on oils.

Hope this helps, it educated me on oils... :mack1::SMOKIE-LFT:
