Engine oil LIQUI MOLY or Shell

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

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.

I've never seen T6 in 15-40. It's always 5-40.

Rotella is the best you don’t even need the synthetic. I run it in my 6 bolt 4G63 with 222,000 miles on it pushing 400 wheel horsepower and I’ve been a truck driver for 29 years it’s the industry standard????????

Rotella T6 ftw! I swapped my F800GS' oil to this and HifloFiltro filters years ago and have had zero issues. ~$30 for a full change compaired to BMW's asking price of $23/quart (straight highway robbery) and $20/filter so it was a no brainer saving almost $60/change

On my 2022 my first change I used Mobil 1 Full Synthetic (always used in my cars). However, my last change I put in Liqui Moly Molygen (green container) and it may be a placebo but I feel like my engine is quieter.

Rotella T-Syn is a great oil but for our turbos...i wouldn't recommend it since if any oil gets burnt or makes it way through the rings...the higher amount of ZDDP (zinc) found in the Shell Rotella Synthetic oil will be harmful to your catalytic converter which may cause a failure.
