Engine oil LIQUI MOLY or Shell

5w-30. I use LiquiMoly Molygen and my experience is good.

I use Shell Helix Ultra 5w40 on my m52b20 E39 and I'm super satisfied

I use it on my 2016 S5 and it’s wonderful. It’s basically the same as Leichtlauf just with the friction modifier and UV capabilities if you need to spot an oil leak (only in the first 300 or so miles because then the oil gets too dirty to work with the UV). I’ve heard the friction modifier works well in older performance cars due to the increased wear of their engines. Yes it’s technically not approved but you won’t go wrong with it.

I use the Leichtlauf High Tech. Really helped my higher mileage SQ5 with chain rattle.

I personally use Liqui Moly. I've tried Castrol, Mobil 1, Amsoil, etc. and my BMW (E85 Z4M) runs noticeably more smooth with the LiquiMoly.

I’ve never had any issues with 5W40 Liqui Moly Leichtlauf.

Eu nu am folosit uleiul ala, dar am pus intr-un 2.0 TDI DFGA, Shell Helix Ultra Professional AV-L 0W30 si motorul este foarte silentios.

I’ve used three oils on my bikes since the mid-2000s: Motol 300v, AMS oil, and T6.

Out of the three, I’d choose T6 for normal street riding with the occasional adrenaline run

Fata de vechiul ulei oem 5w30 este pu\u021bin mai g\u0103l\u0103gios motorul. Eu am trecut pe liqui moly \u0219i pare mai ok

when they were done my GLI it felt GREAT driving it home until me engine oil sky rocketed to 238 degrees…never seen oil that hot in my life and majorrrrrr lag…i thought it was done. put my hazards on pulled over got it towed back to my house then i started it back up and it was running just fine.
