Jarrod Edelen uses Lucas Heavy Duty Oil Stabilizer

This is the gods honest truth. an this is what sold me on Lucas products.A friend of mine bought a 1990 F150 that was in excellent shape appearance wise but the little 5 liter ford had a rod bearing hammering somthing awful. Sounded like a gorrilla in side with a sledge hammer that wanted out. So he changed the oil put 3 or 4 quarts of oil in the crank case started it up and still the rod was hammering. And then he poured in the quart of heavy duty oil stabilizer and i am not kidding you within 5 to 10 seconds the sound got quieter and quieter until it just stopped banging. He kept this truck for another year or so and used it to pull his racecar and trailer and never had a problem out of the truck again and this is the honest to god truth so now i use lucas products in everything i own...
