Engine oil PENNZOIL or OEM BMW

Pennzoil Platinum Synthetic. My 1988 740 has near excellent compression at 245k og miles.

At the very least, make sure you're using quality oil like Mobil or Castrol or Pennzoil.

hey u/op ... if its not too late..\n\ndont drain the oil the normal way! the paint would be carried through the oil passages and possibly hardening in them.\n\nsince they poured/sprayed the paint through the opening, its all in that area.

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

I use Pennzoil Platinum 5W-30 in my 2011 328ix (N51) I believe that is the recommended viscosity.

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.

I use 5w-30 pennzoil ultra platinum full synthetic with the oem motor craft oil filter

I change my oil every 3k miles

I've been using Penzoil ultra platinum full synthetic 0w-20, though it does burn sometimes a quart every oil change.

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