Hi Everyone!

I got my X3 M40i last year and going to do my oil change DIY.

I live in Socal, so just a dumb question, is 5W-40 Leichtlauf oil from Liqui Moly is the way to go?

Or should I just stick to 0W-20 that the car recommends?

Thanks in Advance!

What does it say in iDrive if you pull up OIL types in the embedded owners manual built into iDrive? It should tell you what BMW recommends specifically for your BMW based on its VIN.

Just make sure it’s BMW LL-01 certified.

I just checked the Oil, and it seems to have an approval for BMW Longlife-01. would that be the same?

Thanks!

I did this exact thing. Not a fan of paying more for no reason, so I found the cheapest oil that met this standard.

I doubt about BMW LL-01 at such engine. The oldest I could find as approved was LL-12 FE, but I'd need to do the research for M40i engine.

I think the current version is LL-17 FE. I put in Castro’s Edge that met this criteria.

2019 M40i allows BMW LL-04 according to: https://x3.xbimmers.com/forums/showp...3&postcount=48
I'd avoid 0W20 oil, rather use 5W30, 0W30.
