Shannon R. Farnham uses Lucas Synthetic Oil Stabilizer

Thank You For Saving our ENGINE ! We had a regular oil service with the local Cadillac Dealership. We gave them 1-Qt. Lucas to add to the oil change. 5,000 miles later we went to the local Jiffy Lube to get another change before taking a trip to Florida. The technician came and told me he could not get ANY oil to drain out of my engine. To our amazement, the only oil the dealership had put back in our car was the Lucas additive. The car oil lights had not come on nor had the car acted any way in need of oil during those 5,000 miles. What a awesome product you have. We have told our story many times and wouldn't have a vehicle without Lucas. THANK YOU !
