Hi Everyone,
Any multiple BMW engine owners here? Would love to hear some experience with all the Longlife oil specs.
Well, I have both an N52 and B48 (non-TU, non-GPF), according to BMW ISTA (factory service software), the B48 is compatible with every Longlife spec from LL-01 to LL-19FE, whereas the N52 is LL-01 (and FE), LL-04, LL-12FE, and LL-19FE. Viscoity-wise, these specs cover everything from 0w20 to 5w40.
Before owning the B48, I never put too much thought into oil choice, since the N52 is port-injected and naturally aspirated. I used whatever was cheapest among Castrol Edge, Mobil 1, and Shell Helix Ultra, right now I have a few jugs of Shell Helix Ultra 5w40 SP from a sale.
After getting the B48, I bought 8L of Shell Helix Ultra 5w30 SP LL01, which I know is perfectly safe to run in the B48. Since I still had some miles left before the oil change, I went researching the various BMW oil specs out of curiosity.
From what I have learned so far, LL01 and LL04 share the same HTHS requirement of at least 3.5, while LL04 has lower SAPS and lower TBN (both for environmental reasons, emission equipment and low sulfur fuel right?).
LL01 was apparently originally developed for and tested by BMW using the N52, it was updated somewhere along the way to include N20 and caused Mobil 1 and Castrol to lose the certification for a couple of years. According to Lubrizol, LL04 was developed for N20 and included B48 testing in 2019, and is usually a better base stock compared to LL01. LL19FE seems like an LL04 replacement, but only offered in 0w30.
I generally don't care too much about base stock, and according to this post, LL01 would have better protection at the cost of fuel economy (emission isn't relevant for me since I don't have GPF, local fuel is equivalent to Euro 6 in sulfur content): https://bobistheoilguy.com/forums/t...gives-better-protection-than-ll04-oil.329930/
So far, I feel LL01 would still be the best choice for N52. Can anyone share some experience with the B series engines? Is there any reason to run LL04/LL19FE?
