I agree with Diesel Giant. I tried adding a gallon of VO once to my 87 300D. The only thing it did was to make the engine knock more when it was cold. I've also read reports of waxes coating the entire fuel system from a diesel/VO blend. Some people have had good results with running a gasoline/VO mix. Personally, I stay away from VO and prefer biodiesel or real diesel additives instead.
