Lucas oil additive is the best product ever... our car started making an awful noise on our trip to SC. So bad I was afraid to drive it anymore. I wasn't sure what I was going to do but I had a feeling a lifter was sticking. I didn't have much money to put in it while I was on my trip so I decided to try an oil change and my wife suggested we try some Lucas because she likes to play with the little display they have in the store. Well I changed the oil and added the Lucas Oil Stabilizer. When I started the car right after the change, it sounded just as bad as it did before.... then slowly started to get quieter and quieter... then the tapping just went away.  YAY! now I feel safe to make the trip home. Your slogan of \it works\ is the total truth!

LUCAS ROCKS!
