When company owner Tim Thompson’s 2005 John Deere 544J Wheeled Loader began experiencing problems with its mast, Tim disassembled the mast assembly for repairs. It was the first time it had been removed since leaving the factory where it was assembled.
In the process, Tim and his crew were able to inspect the pins and bushings in order to evaluate the performance of Schaeffer’s grease. What they saw was almost too good to be true: the factory original pins and bushings—with over 23,000 hours on them—showed almost no signs of wear.

Pat Hunke owns Hunkes Transfer, Inc. They are a contract carrier for auto parts stores. Since using Schaeffer products, they have little to no engine problems and no problems with cold weather start up. He is impressed with the longevity of the oil – up to 50,000 miles per truck using Schaeffer’s Oil Analysis.

Thermographic imaging shows Doug Glur’s Harley Davidson runs cooler with Schaeffer’s #707 Supreme V-Twin Synthetic Plus Racing Oil 20W-50.
Ask any biker, and they’ll tell you: motorcycling is a way of life. When it comes to taking care of your bike, you need an oil that will treat your bike as well you do.
