Mike DePalma found increased HP from Lucas Racing Only Motor Oil

I wanted to give you an update.  We dynoed the engine and had great success with the oil.  It was 2-3hp average better that the oil we were using (Gibbs).  Very impressive to say the least.  We have been running Gibbs for two years now and haven’t seen anything that compares.  You guys have definitely done your homework.  We sincerely appreciate all of you help and the opportunity to test and now use your race oil.  Many of the racers come to Craig and I for advice so we will be sure to let them know where we stand on oil.  If there is anything that we can do to help you guys may it be testing or whatever we would welcome the opportunity. Once again we really appreciate the help.
