Four years ago my vehicle could not be inspected because of a very faint sign of exhaust smoke. A retail parts outlet advised using a ( high mileage ) oil, which I did and my vehicle has passed each year. However, I still had to add oil between changes, up to 1 1/2 quarts.
After turning the gear handle on your display during numerious visits, I decided to try your Lucas Oil. My truck has 166,543 miles and is due an oil change at 167,000 and I am happy to say, I only added ( 1 cup ) to stay on the full mark and I only added that because I was going on a trip of more than 500 miles.
Your product has passed the crucial test, that of the consumer.
