Good product by Diablo Sport

Reviewed By Jeremy C (OZARK, MO) —12/4/2017 10:05 AM

I bought this to see if it would slow or stop oil consumption. I have 1000 miles on after install with a fresh oil change. Still shows spot on full whereas normally would be 1 quart low. Added bonus is it feels like I am driving a totally different vehicle not having it alternate between 4 and 8 cylinders constantly.
