Engine oil RED LINE or RAVENOL

Redline recommended 10w-40 Full Synthetic for my 1.8 solid lifter JH turbo application and the tech guy suggested modern synthetics don't cause seal leakage (like OG synths of 25 years ago) and holds up way better than the 40w rating in hot temps and protects much better when cold than even the current crop of Castrol 20/50 dino oil I was running. I swapped over the M81 to the same Redline oil and have not yet noticed any new oil leaks yet.

I think the Ravenol VSE 0W-20 is a good performer, based on these tests.

So, I recently drove 2 oils: NGN Emerald 5w30 and Ravenol VST 5w40. I watched the oil temperature displayed on the route book display in different modes, but there were no problems with the temperature.

I used Ravenol VST 5w40.

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.

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 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.

I use only Redline for all my oils-fluids. For engine oil, I have used 10w40 consistently.

Has anyone here tried Ravenol yet? I've been using Liqui Moly's TOP TEC 6200 VW 508/509 but read around that this oil below is also good if not better.

Used to use Motul, now switched to Red Line for the higher zinc content and high heat stability. I rallycross my daily so high RPM and high heat.
