Why don't you go right to the horses mouth and ask Schaeffer your concern?I know lots of fellow excavators who like me run Schaeffer and they have a few million miles on their fleet.Their engines are clean as a whistle.And if you're running bio, why are'nt you concerned about your fuel filter clogging? Schaeffers#--314-865-4100Horsehaulin;1558310; said:I have been doing some reading about Schaeffers, and I found their synthetic oil is based of a parrifin base. Knowing what I do about #2 and the waxes and parafins in that fuel, I dont want that in my engine. Bio-diesel breaks down the parifins in a fuel system depositing them into the filter, what is going to keep that same parafin from clogging the oil system? After years of use, something has to get clogged up same as the fuel system.
If I am wrong in thinking this way, then someone please chime in with something scientific to disprove my thought.
The transfer case uses ATF, so you can use TranSynd or any other good ATF fluid. The front and rear diffs. can use oem GM grape juice, Mobil 1, Lucas Syn., Royal Purple, Valvoline Synthetic, and Schaeffers, and probably a couple more I haven't mentioned...avc8130;1556593; said:I want to change my front and rear diff fluids along with my transfer case. What type of fluid do I need and what is the best?
I was thinking of using Royal Purple fluids.
Sorry--I don't buy it.hpprose;1563118; said:I was working on an article for TEN Magazines on fuel economy. Doing the road testing as consistant as possible, I gained 2 mpg by switching everything over to Royal Purple. The testing was conducted at 67 MPH over 300 miles.
That has worked with tractor trailers in many different tests. They tried all combinations of synthetic and mineral oil. If you put synthetics in everything suck as transmission, differentials, power steering any anywhere else there's fluid there is about a 1/12 - 2mpg increase. The synthetic crankcase oil had minimal if no influence on the results.[email protected];1563979; said:Sorry--I don't buy it.
