"My grandfather has Johnson 150, it has been going thru oil like crazy. This happened all of sudden. We are using about 1 gallon of oil per 4 hours of run time,approx. 20 gallons of gas. varying speeds, mainly 3/4 to WOT. VRO pump going bad? oil pump going bad?"

"from what ive read a lot of people take them off and throw them, then run mixed gas at 50:1.
