Engine oil Mannol or OEM BMW

3.0 n52 when I got the car it had 5w-30 and the oil was leaking slightly. Changed 5w-40 and the leak stopped all together. Engine is smooth as butter

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.

I am using this exact oil at the moment and have no complaints.

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.

Mannol is a legit brand. Although not as critically acclaimed like Liquimoly, Rowe, Fuchs, Addinol, or Ravenol. Probably on par with Voltronic.

Using Mannol for my diesel.

Oil leak. Thats my G20, had to fill like 3 times oil myself during 30 000 km. Went to service and apparently they found two separate oil leaks
