Engine oil RAVENOL or IDEMITSU

I don’t use the Mazda-branded version, but Idemitsu is my go-to oil in all of our Mazdas

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.

Idemitsu is the only premix and engine oil I’ll use ... you can order it for a good price from TREx performance out of NJ and he will ship

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.

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.

The oil was Idemitsu Synthetic 0W-20 with 12.5k miles on it. Once again, trace metals and flashpoint were within normal range. I also ordered a TBN to measure the amount of additive left and that showed there was still plenty of active additive remaining.
