Engine oil Shell or FUCHS

I use 5w40 shell helix ultra on my 520i. It doesn't burn a single gram, it's relatively inexpensive (cheaper than the liquy moly I used to use) and is BMW long life 01 approved. The car runs smoothly, I'd recommend it

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

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.

I have oil analysis done in my TDI and a 10K OCI is a reach. The factory fill was almost depleted of wear additives at 5,500 miles. Fuchs Titan GT-1 was still serviceable at 7,000 miles, but I would not have carried it out beyond that.
