Paul Martorelli uses Lucas Heavy Duty Oil Stabilizer for 1990 GMC Van

Hello, my name is Paul Mo

I own a automotive glass company named All Mobil Glass. My work van is a 1990 GMC Van with a 4.3 V-6 engine. At 140,000 miles my rods started knocking. I put Lucas Oil in the engine. Now I am up to 203,000 miles and still running strong.

Just want to say thank you for a great product.

P.S. You must have a real good chemist
