Engine oil Motorex or OEM BMW

5W-40 is my preferred viscosity for the N52. If you are only topping off, virtually any API SL or newer oil will work just fine. If you are doing a full change though you should source a 5W-40 that meets BMW’s LL-01 specification.

As long as it’s a LL-01, you can put that in. I’m currently running that on my N52.

10w60 is the only oil you should put in these. If nothing else, you can usually find it at BMW automobile dealerships as that is what they put in the M3/4 series (or at least used to). Not cheap, but a lot less expensive than engine rebuilds.

At the end of the day, pretty much anything in spec will work fine.

That being said, I did a bunch of research for my V85 and determined that Motorex Cross-Power does the best in high demand applications. Air cooled engines can have a really wide temp range. That's what I use.

A lot of people are essentially saying "don't beat on it until that gauge reads warm," which is incorrect. BMW, in the G series, switched to showing *coolant* temperature on the speedo and not oil temperature. That is NOT the oil temperature gauge, and oil takes a lot longer to heat up than coolant. When that gauge shows operating temperature, give the car another 10 minutes or so to get the *oil* up to temp.

Just drive it. With these 0w20 oil is circulated immediately. My G20 330e does a cold start when accelerating the highway. The RPM limit is protecting your engine so even with a kickdown it won't go above 4k RPM and will shift very early.

i drive a g21 330D xdrive, I've been researching warm up procedures and people recommend letting the oil circulate for 30+ seconds then cruising in eco pro as the torque band is toned down and it changes gears as early as possible.

Lots of BMW's as they get in to the upper mileage tend to start consuming oil one way or another.

It takes a “synthetic blend” of motorex 15W50 oil. And uhh yeah works good I guess, don’t have to change it too often, and as far as performance goes, it doesn’t really matter because I’m on restricted power anyways so yeah ????‍♂️

10k miles later, went to do my usual 1k mile quart of oil, looks like chocolate milk.
