Schaeffers oil

[Whitepark]

Has anyone used Schaeffers oil? what is your opinion on their synthetics? my neighbor uses it in his diesel equipment (IH combine, 835 Versatile with Cummins, semi with L-10 Cummins, JD 4630.) He likes it and is going to switch over to their synthetic hydraulic fluid, He also gets free oil analysis with it and they seem to be honest, and actually said he doesn't need to change his oil so often, I would have expected them to want him to change it more.
I want to get an oil that I can use in all my equipment so I don't mix oil or forget what I am running, I plan on getting it by the 55 gal. barrel and running it in gas and diesel engines. has anyone had experience with this company? is their oil junk? thanks a bunch, Whitepark

Whitepark, I've never used Schaeffer's oil but our local electric utility began a program about a year ago using the Schaeffer synthetic BLEND. They have extended the oil drain interval to 1000 hours on the diesel trucks that transport the diggers and personnel lifts. They use no additional filtration but take oil samples regularly to monitor the oil and engine condition. It saves them money and has a positive inpact on the environment.
