engine oil

Hi all, I need to add oil on the engine of my z4 3.0 si coupe(at 82000km)?

I was recommended Castrol.

Which brand is the better?

Regards

The oils listed below meet BMW’s Long-life rating and are acceptable for use in BMW Passenger vehicles and SAVs in the US market with gasoline engines.

BMW Long-life rating LL-01 Approved Synthetic Oils for the US Market

Castrol Syntec European Formula SAE 0W-30
Mobil 1 SAE 0W-40
Pennzoil Platinum European Formula Ultra SAE 5W-30
Valvoline SynPower SAE 5W-30

Use only oils with an API rating of SM or higher.

The choice of the right SAE grade is based on the climatic conditions in the region in which you normally drive your BMW.
This is the former recommended oil list before they switched to the new one

this what I could find in the seller. I add only 1 litre on the engine and and the yellow warning stopped.

It matches the spesificatioın you gave to me. But I have a question now that should I use 5W-30 or 0W-30, which one is better?

On the other hand I consider to renew oil in the engine completely? Is
it make eany difference in the performance? Is better oil better performance?

thanks for all post from you.

regards

Mobil 1 full synthetic 0W-40 should be just fine. Relatively cheap if you purchase 5-quart jugs from Walmart. Then buy some OEM filter kits from like Tischer BMW ( http://www.getbmwparts.com/partlocat...egoryID=103121) or something. I believe the non-M engines use the same filters as E46? I could be wrong, but you can still navigate that site as needed and purchase what you want.

I'm driving 3.0 si coupe, not M coupe. Is OW-40 suitable for me?

As for filter I ask for my service to change it when I completely change oil.

Yes sir...Mobil 1's 0W-40 is perfect for non-M engines. I use it in my E46 325Ci, which uses the same grade of oil as the 3.0L variants.

M engines require 10W60.

Hi all, today after stop my car I had a warning on the screen displaying engine oil pressure sign. I checked the manual and then checked engine oil level. It needs to be added 1 lt new oil. Actually I'm suprised because I fully changed engine oil in BMW service about three months ago with Castrol Full syntetic 0W-40. Now I need your ideas. Is it normal engine oil requirement in a short time about three months? It's 2007 3.0 si coupe.

It is definitely not uncommon for an engine to "eat" or burn oil, but it's unhealthy if it's burning a full quart worth in such a short amount of time. Maybe take it in to have looked at? You may have valve cover leakage or some other kind of problem.

It sounds scary, but isn't too bad. Usually if it is the valve cover, then all you'll need are new gaskets (which are just rubber seals around the edges of the valve cover).

And how many miles did you drive in the 3 months? Milage, not time is going to tell us if you have a problem or not. Using 1 litre every 1-1.5 thousand miles isn't uncommon.

I did 4000 km in this period.

By the way I went to BMW service. Service guy says burning oil is normal in BMW models. He changed oil with 10W-60. Now I will monitor how long will it take.

Why would they put 10W60 in a non-M engine? I think that is too thick an oil for your engine...
If they're trying to prevent oil from burning by introducing thicker oils, then I think you should stay away from servicing with them in the future
