Agreed. I mean there are plenty of LL-01 oils available and the non-LL-01 oils are not really any cheaper, so there is no reason not to use the recommended stuff. I use Castrol 0w40 in pretty much everything now, including my snowblower.

Yeah it's basically a solvent with some mineral oil in it. It's just funny when I see people recommending adding it to your crankcase with every fill.

Is there any BMW LL01 high milleage oil?

I would just use Castrol LL01 0W-40. It's thick enough to reduce oil consumption, if that's your issue currently.

[9krpmrx8]

All LL01 certified oil is meant to be used for 10000-15000 intervals so it is automatically "high mileage" oil,

I heard it is similar to auto trans fluid.

Castrol 0w-40 ftw. Cheap, readily available, great specs across a huge spectrum.

Not just any castrol tho, has to be the Edge a3/b4 Euro formula one for LL01.

Just a reminder if anyone doesn't know.

For anyone that cares enough, Castrol 0W-40 A4/B3 has really impressive stats. (Assuming that Castrol publishes real data which i think they do)

Viscosity, Kinematic 100C 13.5 (True of 40 weight)
Pour Point -60 Celsius (Excellent and true to only group 4 stock)
Viscosity Index 169 (Excellent, true again to group 4 stock)

Good all round oil esp good for cold weather and cold starts.

How true you stay to Manufacture spec is EXTREMELY important for turbo engines and hydraulic lifter engines. As well as engines that have Pistons with a small confidence of expansion. (Alot of modern cars) . Viscosity Index Is also very important as the oil viscosity transforms from cold temp to operating temp.

Alot of people here are throwing comments like LL01 doesnt mean anything. There is alot that goes on to approve oils for manufacturers. Not just 0W rating and operating temp rating. The SAE is old and vague. Today its all about additives and viscosity index ratings. The ability of the oil to change to temperature.

When I went to buy oil they were sold out of the Belgian-made Castrol Edge 0w-40 that I wanted and I ended up buying the Castrol Edge 5w-40 (USA made) which also has the LL-01 approval.

I'm not aware of any LL-01 approved oil that's designated as 'high mileage.' From what I can tell, most of the high mileage oils have seal conditioners to help swell seals and prevent leaks. Personally I don't think those sealing agents would do anything to slow the common E90 leaks (oil filter housing gasket, valve cover gasket, oil pan gasket), and I'm using plain old LL-01 approved synthetic oil for my *very* high mileage N52 (223K to be exact)

My previous oil change was made with Mobil 1 0W-40 (which is NOT LL01 approved any more but I don't care) I consumed 1 quart per 2000 miles. Since I've done the oil change with the Castrol Edge 5w-40 I've driven about 1000 miles and I can see my oil level dropped to the halfway mark so consumption is the same as the Mobil 1. My oil pan gasket is leaking but not much - the pan gets damp but there are no drips on my garage floor or my parking garage floor where I park during the day. There are no other visible leaks and no smoke whatsoever coming out of the tailpipe, however after I park my car I can smell burnt oil under the hood. Despite a recent valve cover gasket change and no leaks around the front or sides of the engine, I haven't checked the back of the engine yet. I also suspect there may be an issue with the PCV piping and/or oil separator (magnesium valve cover N52, oil separator is external and under the intake manifold).

Oh I didn't know there was another LL01. The US oil you bought, does it say a3/b4 on it? Or just 5w-40.

Yep true. High mileage oil really is just to try and help and conditions seals. And I agree it wouldn't do much for those gaskets. I would see it do things to like the main seal and more internal deeper seals but usually those are not to much of an issue as it seems.

The high mileage doesn’t typically refer to the change interval, but to the cumulative miles on the odometer...

True that! Similar to the old 0w-30 ‘GC’ that I used to collect when on sale. I consider 0w-40 edge LL-01 as it’s cheaper more readily available.

[Welcome to NBA Jam]

Just use LL-01. That's all you need.

[Nickco43]

I pay $12 per oil change for return shipping to FCP Euro. I do not know why everyone doesn't use FCP Euro's OEM oil. No need to use meme oil from the autoparts store.

I started buying items that wear out from them to return such as wipers and air filters. But I don't think its worth it for something as nasty as oil. In the spring time you can get get mobile one for around 10 bucks for 10 qts with rebatres. So it comes out a little more but I don't have to ship oil.

[Fritzer]

130,xxx here. I have a couple quarts of High Mileage Mobil 1 5W-30 for emergency top-offs. Just picked up two oil service kits over Black Friday of Pentosin 5W-30. Never used it but heard good things. This last interval I pushed it, so I'm going to cut the next two intervals in half to get a good flush. Never used Pentosin but hear good things about it, it's LL01 and got each kit for $50, fluid, filter, and gaskets. Can't complain!

Clarify please. What are you returning to FCP?

I think I read a thread a while back about people going over the benefits. Apparently there are some, but minimal. Probably worthy of meme oil status. I see way more people with high mileage N52s saying that they have only run LL01 BMW Genuine 5W-30, or OE equivalent.

The oil and filter probably.
