Michael uses Lucas Heavy Duty Oil Stabilizer in his 1974 gmc pickup

I have a 1974 gmc pickup with over 500,000 miles on it and it was burning 1 quart of oil a week until I started using the oil stabilizer. After putting the stabilizer in I didn't have to add another quart of oil for 1 month. The truck seems to Idle smoother now as well as the oil pressure is much higher. thanks for a great product.
