WMO/ATF/Synthetic/W85 Questions

4007 Views 11 Replies 6 Participants Last post by  dieseldonn
I'm going to start running W85 in my truck in the next few weeks as soon as all my supplies get ordered/shipped and I can do my first filtration. I'm going to go with a pabiodieselsupply 120gph centrifuge setup for my 2000 PSD. With the centrifuge, it will be extremely clean at .5 microns. My source of fuel will be a mixture of synthetic/non synthetic WMO & ATF.

Here are my questions:

1.)Can I just start running W85 immediately or do I need to wean the truck onto a W85 mixture?

2.) If I run out for whatever reason, can I immediately switch back to a few tanks of straight D2 on occasion?

3.) Is there any problem with running large amounts of synthetic?

4.)Any problem running a random mixture of WMO & ATF with 15% UG?

5.) Any problems with dumping a mixture of W85 into a tank half full of straight D2?

I get all my oil from a BMW dealership, probably 98% synthetic, and I've never had a problem. Runs great IMO and easy to thin out.
