Engine oil VALVOLINE or RAVENOL

I'm using "Valvoline Modern Engine Oil" since they have patents and claim to have some chemistry there to keep the valve stems more carbon-free.

I bought this unusual oil made in Germany Ravenol NDT 5W-40...my truck has never sounded or performed better. I was hearing a little bit of top end noise at idle and that's complete quieted with this oil, as well as throttle response and overall smoothness of the engine and turbocharger increased greatly.

Just change it.

I have a Yaris with 300,000 miles on it. All I use is conventional 5-30 Valvoline.

I always use VR1 (Valvoline) 20w50. Excellent oil. The car runs beautifully on it and has had no issues.

Nothing but the best. I personally use Ravenol. I have a bew and very particular about our because of cam issues. I would only substitute this for liquid Molly.

I use the red bottle in mine. I've found that it leaks/burns the least.

I have the VR-1 race oil on my MR2. Apparently some people said it made my car spit flames.

Me personally I'm using Valvoline euro full synthetic 5w 30

I just ordered the ravenol after watching a youtube channel (sergiu gabor) where ravenol yielded the best results of simulated wear indication tests against various oil brands.
