LL17FE 0w20 for N20/N26?

My car will be due for an oil change soon and apparently dealer is now using LL17FE 0w20 on 4-cylinder. Anyone has experience with this LL17FE oil?

LL= Long Life. That's a BMW trademark.
17= The first year BMW used it, 2017. It may or may not be appropriate for earlier model years.
FE= Fuel Economy. 0w-20 is thinner than, say, 5w-30, so drag between parts is lower, fuel economy is higher.
If you want to err on the side of caution see what grades are listed in your manual as acceptable for your engine.
I'd be leery of a dealer who's using 0w-20 in every car.

From TIS it shows N20/N26 as eligible for LL-17 FE+ so it's not technically wrong.



However, my manual doesn't list it (because car is 2015). Below are the oils I would use (my last change I did LL-04 only because I am in Europe and use the gas here).

83212365946 - BMW TwinPower Turbo 5W-30 LL-01 (all gas)
83212365949 - BMW TwinPower Turbo 5W-30 LL-04 (all diesel, EU gas only)
83212365954 - BMW TwinPower Turbo 0W-20 FE+ Engine Oil LL-14 FE+

And some more info from another place:

Quote:
For differentiation purposes, the oil specifications are designated according to the year in which they were first used as:
"BMW Longlife-01, -01 FE" (2001),
"BMW Longlife-04" (2004),
"BMW Longlife-12 FE" (2012)
and "BMW Longlife-14 FE+" (2014).

From a past thread https://bobistheoilguy.com/forums/ub..._stringent_Eur :

The categories "BMW Longlife-01", "BMW Longlife-01 FE" and "BMW Longlife-14 FE+" as well as "BMW Longlife-04," and "BMW Longlife-12 FE" are qualitatively comparable but differ with regard to minimum viscosity at high oil temperatures (HTHS viscosity).

BMW Longlife-01 / -01 FE / -14 FE+ oils are only suitable for gasoline engines, while BMW Longlife-04 / -12 FE oils are suitable for diesel engines with
particulate filters, due to the reduced sulphate ash content.

LL-01 (ACEA A3/B4 base) requires the N20 performance test, N20 Aeration test and N42 Valvetronic RNT test
LL-01 FE (ACEA A5/B5 base) requires all the LL-01 tests plus the N20 Fuel Economy Test and has lower limits on HTHS and specifies a minimum KV100 of 10.0 and a minimum TBN of 10.0
LL-04 (ACEA C3 base) requires the same testing as LL-01
LL-12 FE (ACEA C2 base) requires all the same tests as LL-01 FE plus the N47 AATL carbonisation test and the N47 Fuel economy test. It also has even lower limits on HTHS and requires a minimum KV100 of 8.8 and a minimum TBN of 6.0
LL-14 FE+ (ACEA A1/B1 base) requires all the same testing of LL-01 FE but at minimums of HTHS 2.6, KV 7.8 and TBN 9.5

Mine is 2013 so manual only lists LL01 and LL01FE, but dealer has been using LL14FE 0w30 for the last few oil changes.

My strategy is that, since 0w20 has reduced drag, it can help with N20/N26 TC, provided the car is not tracked(which can stress out HTHS 2.6-3.1 FE grade).

I used Castrol 5W-40 which is LL01 on my F30, 2016.
Do not see a problem.

Any particular reason Bill? Even a 5w will flow in Temps of -40 F. I really don’t give it much thought since the coldest it ever usually gets where I live is low 40’s on a cold winter night, so I use a 5W-40 year round. Is it because a 0w just flows more readily when cold?

It's not the 5w that's a problem, it's the 40. In really cold weather it takes a long time for the oil to get up to operating temperature. In short trips it might not get there at all. Winter up in the Great White North low 40s isn't a night time low, it's a day time high, on a really nice day.

Here is the updated info from TIS in case anybody needs it.



Part numbers have changed as well:

83212365946 -> 83212466454 BMW TwinPower Turbo 5W-30 LL-01 (all gas)
83212365949 -> 83212466457 BMW TwinPower Turbo 5W-30 LL-04 (all diesel, EU gas only)
83212365954 BMW TwinPower Turbo 0W-20 FE+ Engine Oil LL-14 FE+ (all gas US, Canada, EU)
83212461990 BMW TwinPower Turbo 0W-20 FE+ Engine Oil LL-17 FE+ (all gas)


I am still sticking to LL-04 in Europe and would use LL-01 when I get back to the states. The newer LL-14 and LL-17 oils came after the F30 was out, are 0W-20 instead and seem to focus on longer change intervals which I don't like.
