Red Line 11605 Motor Oil by Red Line Oil

Excellent. Highly recommend

I will admit I was a user of Royal Purple for years until I tried Redline. Redline made my 02 chevy avalanche run smoother and quieter and might have even picked a couple of more miles per gallon since I changed to this oil. It's more expensive but I think it's worth it in the long run. I used to change my oil at every 3-4 k with royal purple. I am going to try every 5k with redline and see how it does. Awesome performance also out of my 5.3 vortec. Loving this oil so far!

Switched from Liqui Moli which was super noisy at startup. No more noise on cold start ups and runs butter smooth. Makes the butt dyno feels good. Overall a solid oil and would highly recommend. E92 M3

I've been using this in my track car for years (over 100 hours of road courses, and at least that many autocrosses). Never had a problem, maintains viscosity with very little blow by in the catch cans. Would seriously recommend.

I use this oil exclusively in my Shelby GT500 pushing 1,000 HP. It is amazing oil and I'll continue to use it.
