Ray Rudd uses Lucas Heavy Duty Oil Stabilizer for Personal Truck

Dear Sir,

My husband put Lucas Oil Stabilizer in our car and truck. Yesterday he was out and the oil pressure dropped to zero. He drove the truck another 7 and a half miles and the truck did not knock or ping a time. Thank you so much for your wonderful product.

He has a ATV and Motorcycle repair shop and will be telling Everyone about Lucas Oil Stabilizer. We are so happy to find a product that lives up to it advertising.

Thank you again for saving us ALOT of money rebuilding the motor. Thanks to you and your wonderful product we fixed our problem for about $50.00 instead of $2500.00.
