Engine oil VALVOLINE or Shell
I use Valvoline Synpower
I’ve gone down an oil research rabbit hole many a time. There’s been some extensive studies done and besides liqui moly, studies have shown that Valvoline extended protection has some of the best wear-prevention additives and performed among the best in lab samples pulled from used oil.
BEST OIL FOR A MOTORCYCLE IS SHELL ROTELLA 15W-40
Lately I’ve been using Rotella T6 in my 01 330i . Usually that or Mobil 1
It will work. I prefer the T5 semi syn. Seems to run quieter.
Well, every shift I made from 1-5 gear was smooth af, with the other oils (motorcycles specific oils, tried them all) it just clanked a little the more the gear went up, that “kick” or “clank” made me feel like I was shifting
But with this oils It is so fkn smooth I can’t feel the gears going up or down, it just feels like it just goes up or down on gears without a single clank, noise or feel
Also it doesn’t feel like the clutch slips and engaging the clutch feels smoother
My current favorite is valvoline 5w30 full synthetic. There are oil analysis of new that show it has a high 100 C viscosity and it has a ton of really good additives.
Shifting feels smoother, I stopped feeling the sensation that on high revs the motorbike stopped accelerating (clutch slippage???) and I finally find neutral easy at stops, sometimes I have to rev it a little with the clutch pulled, also I don’t feel the kick when clutch engaged
We have been using T6 in all our race engines for over 10 years
Great stuff, wet clutch wear is good and the engines look great inside when we tear them down for rebuilds
I have used it for years in motorcycles. I have tried other super expensive oils and some of them shift a little nicer for longer, like Liquid Moly. But, T6 is a very high quality oil and I still use it and change it when shifting feels clunkier or 5k miles whichever comes first.
