Fred Parks uses Lucas Heavy Duty OIl Stabilizer in 2000 1500 Dodge Ram

In December of 1999 I bought the Dodge. I have a pilot car service and travel all 48 states. It now has over 500,000 miles on it. I started using the oil stabilizer at just over 100,000 miles. The oil pan has never been dropped nor the valve covers been pulled. Also at 400,000 the power steering unit started leaking, and now with your product it has stopped. I just want to thank you for making a product that has kept me on the road. Thanks again.
