I have recently used a produce that surprisingly has given me better results then I thought it would. The produce in question is Lucas Oil Stabilizer. Like always, I change my oil every 3K miles, religiously. I used 4 quarts of Castrol 10W-30. But this time I used 1 quart of Lucas Oil Stabilizer. At first I didnâ€™t feel any difference, until I went on a long, up hill drive with my family and some groceries from SAMâ€™s food warehouse. It really made a hell of a difference. Temp was lowered, gas mileage was up, and the torque going up hill was great. Even the engine nose was down. I think you guys should check this out on your next oil change.
