Denny Syvertson uses Lucas Heavy Duty Oil Stabilizer for 1997 Chevy Suburban

Thought you would like to hear about another success story concerning your Heavy Duty Oil Stablizer. My 1997 Chevy Suburban is equipped with the GM 454 cubic inch engine. We bought it new and it now has 93,000 miles on it. We have complained since we bought it about how noisy the engine is when you start it. We have repeatedly been told that we shouldn't worry about it. Rumor has it that GM tried to fix the problem because of the many complaints by increasing the size of the oil ports and by changing the valves if the noise was too loud. They finally gave up. Too bad they didn't recommend your oil stabilizer.

Last month I discovered your products in the Montana Motor Supply store here in Livingston. I purchased a quart of the oil stabilizer as a replacement for one of the seven quarts that the 454 engine holds. The next morning when I started the engine I couldn't believe the difference. It no longer sounded like a diesel engine and didn't sound like the valves were changing holes. I just purchased another quart for my John Deere tractor.

Hopefully, other owners of GM 454 engines will give your products a try.

Thanks again for a produc
