Badams Posted April 12, 2004 Share Posted April 12, 2004 I am not sure about a Lexus but I have run Airplane Grade Gasoline in a Porsche 928 and the results were interesting. Better Gas Milage was notable but acceleration appeared to be about the same according to what I can remember. I would call and anonymously talk to a Lexus Mechanic if you can.
