Interesting thread.

I don't filter my WMO and just pour the gallon or so directly into my fuel tank. Then again, a few gallons of synthetic WMO per year mixed at less than 5% isn't going to hurt anything. I figure the oil has already been filtered thousands of time by the oil filter, so it should be good to go into the fuel tank.

I've heard of people on the Dodge Ram forum running 100% WMO without issue. Most recommend a 50% mix though.
