Engine oil LIQUI MOLY or MOTUL

I run 300v Motul. Much better than Motorex cross power in my bike. Also tried Motul 7100 but that was no better than the Motorex. Have to change oil at 5000km with 300v, but I do that anyway or earlier.

I used this because it was on sale:

Liqui Moly - 0w-30 Oil (5 Liter) Top Tec 4210 (504.00/507.00 spec)

I figure if it meets spec, cheaper is better for a midcycle top change.

Motul x-clean EFE. Went back to 5W-30 since I saw some MPG lost (the STI is DD).

Motul 8100xclean 5w40 during the summer since I'm in az and every day is 100+, the 5w30 loses its viscosity too fast in the summer

I use Rowe oil or LiquiMoly in my TDI, been happy with either.

Motul 8100 xcess 5-40. I got a built shortblock and it’s the best for the boxer engine IMO

Only use Motul 8100 5w40. I have after market parts and turbo.

Only use motul. XCess gen 2 5w40 for the ‘04 wrx. I get oil samples sent to the lab on the wrx and it has consistently been improving results since switching to motul. At first they were worried about the motor and now they say it looks clean as a whistle

Always used Motul 8100 xclean 5w30 every 3k miles on the dot.

I'm not trying to put down LiquiMoly as a brand, but SAE is SAE. Now I wouldn't choose like a cheapo store brand, but big brands like Valvoline, Pennzoil, Mobile, those are all gonna be pretty much just as effective at completing the job they were designed to do.
