This is probably a crazy question, but would simply adding a 2% ratio of vegetable oil to your fuel at fill-up cause any problems
. I know it will help lubricisity. I understand if you preheat the motor it will run on straight vegetable oil, but would it cause problems as just an additive to fuel. I figure it would take about 1/2 gal for a 25 gallon fill. I would just switch to biodiesel but the only place I know of locally is 25 miles away and I don't go that way very often. Although at $2. 00 a gal it's quickly becoming cost effective to do so. I used to run Power Service and it did help the mileage a little, but not enough to be cost effective. But from what I've learned here it does very little for lubricisity with the new ULSD.
