what does the rug do to the oil? ive always been taught never to run gas in any diesel cuz of the damage it can do.
I don't run much wvo, but is your ATF clean or used??
IMHO, if you would mix the two together shouldnt hurt anything. Most places throw all of that oil together, unless your getting it from a transmission shop.
That mix you talked about should run good.
ive ran a tank full of 100% wmo and it needed starting fluid to get her runing and she ran great with it
