Engine oil RAVENOL or IDEMITSU

Even Ravenol, which is pretty expensive since it is made in Germany from Group V base stock. Great stuff.

I used to have castrol but since i chiptuned my octavia i switched to ravenol and the oil temps went down a good bit and it doesnt use any oil but that could also be because the old oil was 0w20 and the new one is 5w40

Last month I replaced the valve stem seals and it helped massively with the smoke. It doesn't really smoke much anymore, there's definitely still small puffs when taking off quickly, but nothing that I can see in the mirror.

I think Idemitsu is the better option if you have access to it. Mostly because it was developed for the rotary engine.

I go with 10w40 Ravenol TSi

Idemitsu to both, because it’s designed and tested on rotaries.

I use idemitsu rotary 20w50

I stick to Idemitsu. I have a Sohn adapter fitted, so it's 10-30 Idemitsu in the engine, twice a year and Idemitsu Premix in the Sohn adapter and in the fuel tank.

I use Ravenol which is 100% PAO base stock.

In Germany we driver Ravenol RCS 5w-40 and Archoil 9100....sick combination. i drive it in my c63s and gle63s and volvo S60....
