Lucas must be making a boat load of money. Their advertising is everywere in racing circles. A friend in off road racing has a sponsorship from Lucas but lost it when they found out he was using Red Line. He said the sponsorship represented a contract to put the stickers on his car and do other promotional work. He said that after using their oil he switched back to Red Line. This is all just his opinion of the oils but he did do a bunch of uoa's and of course he had the advantage of basing his opinion on tear downs, something most of us don't do. He did say the Lucas people were a great bunch to deal with and they were very good to him, but he choose to use another oil inside the engine. He never had anything bad to say about the oil and uses in in his gas engine transporter truck, big block Chevy, and his generators, Onans, and for that he said it was a very good oil. For our purposes, mostly street drivers it sounds like a yes vote for Lucas. He also said he tried the Lucas gas and oil additives and could not figure out if they did anything or not and went back to Chevron once an oil change and Red Line gas additives every fillup.
