What oil?

for some reason, and probably a glitch of some sort, LM's website only recommends their 10w60 for cars prior to 2010. look up recommendations for any BMW that calls for 10w60 and it will say "only for <2010". I emailed them to see exactly why?

Not sure if Molygen is available in grades other than 5W-30 and 5W-40, but those grades carry no approvals whatsoever. They are “recommended for” a bunch of specs, which for the 5W-40 includes LL-01.

Whoops, thought the new LM oils were Molygen, they're under a different line: https://www.liqui-moly.us/en/press/p...moly-4402.html

Fun fact I just found out. The only ones that recommend Liquimoly is Liquimoly.

Castrol is obviously approved by BMW.

If it's approved for the standards of whatever motor you're pouring it into (LL01FE I think for the new oils?), it will be fine.

Guys what would be your thoughts on liqui moly molygen "New generation engine oil" (not for our M3s of course)? It feels kinda weird pouring something that looks like mountain dew in the motor :-)

Castrol Supercar! (TWS) 10w-60

Where's icecream? I remember he spun a bearing after switching from TWS. Might have been coincidence, but it seemed to be the only thing that changed

The cheeseburger you ate yesterday isn’t want caused a heart attack today. The engine blew because it’s bearings had taken enough of a beating.

Liqui Moly Race Tech GT1 10W-60

Does anyone have a VOA for Liqui Moly 10W-60? I found one for TWS but not for LM yet.

Comparing product sheets, TWS is thinner than LM at 212 F/100 C. This trend seems to be the same but less significant at 104 F/40 C. I've seen the argument that even TWS 10W-60 is on the thicker side of what an S54 really needs, and the LM seems to be even thicker. Probably why people see lower (aka delayed increase) temps on track with LM. In theory that could make bearings lubricate less readily? I'm not sure.

IMO the real test is to wire up an actual oil pressure gauge to see how thin you can go while maintaining the pressure levels the engine needs at track/street temps. But I don't have the desire to blow any engines up...

Probably seemed that way because no one had been looking inside the engine.
