OEM equivalent oil

[O3X5]

Which one is the closest? I haven't seen how much a quart is yet at the dealer, just did an oil change with the ECS kit but I have a leak.

Thanks

Don't know which one is really the same or very similar. Why do you want to have a "copy" of the oem castrol stuff?
If you are just looking for an oil which won't harm your engine or your warranty (and fits your car) just go with an approved BMW Longlife Oil (for example 01 should fit your 2003 M54).

I'm using Mobil1 over 10 years now in all BMWs and am very satisfied (no beige smear/clog for example if you are driving short distance). But this is very subjectiv, everyone swears the oil he or she is using will be the best because of something

Look for the BMW LL-01 approval.

Any BMW LL-01 rated oil is good to go.

lol what warranty?

LL-01 got it, thank you.

You are right, that was quite a bit hypothetical

[O3X5]

haha

Mobil1 is one of the best though, was just asking for an equivalent because the dealer is a bit of a ride for me so in case of an emergency I can go to an autozone or pep boys.

Mobil 1 0W-40.

New formulation of M1 0-40 is not LL rated, FWIW.....

[spadge]

LL-01 (used by myself in M54):
"Mobil 1 New Life 0W-40"

LL-04 (may also be used for LL-01 vehicles, but some people say they are not as good as LL-01 for cars which are rated LL-01):
"Mobil 1 ESP FORMULA 5W-30"
"Mobil 1 ESP 0W-40"

Note: you have to look for the exact name, there exists a "Mobil 1 ESP 0W-30" which has no LL rating...
