Been using Mobil 1 0W-40 on my E46 (M54) and E61 (N54) for years. I change it out every 12,000km or so. They have been running great.

Nope. 176k. Only had 5w30 dealer oil since new, and around 125k I switched to Liquimoly Special Tec LL-01 5w30 & 7500m intervals. Always heard/read good things about LM oils & I like their easy pour 5L bottles with the collapsible spout.

I haven't used 0w40 in my car before. I initially thought we should only use 5w30 or 5w40 BMW LL-01 approved oils. Then I read about Mobile 1 0w40 and seriously considered using it but was still a little hesitant because it wasn't 5w40. While I was searching for a 5w40 oil I came across Shell Rotella T6 5w40. At the time Lamborghini dealers in the US couldn't get Shell Helix Ultra 5w40 and used Shell Rotella T6 5w40 as a replacement. I've been using it since and that was about 13 years ago. I change my car's oil every 5K miles which may be overkill for some people. But it's easy for me to remember without a sticker. The last time I changed my car's valve cover gasket the top of the engine looked very clean. There was no sludge in sight.

liquimoly leichtlauf is one on the best to manage the oil burn/loss. but even that liquimoly and the many ccv repair/delete options don’t solve the problem completely.

ultimately you have to do something about the clogged piston rings. good suggestions i have found here are to soak them in bg or replace them with the mahle rings which have bigger drain slits that aren’t so easily clogged.

I have used Mobile 1 0w-40 a few times in the past but usually use Castrol 0w-30 European formula.

I've used both Mobil 1 and Castrol Edge 0w-40 in my 325xi almost exclusively. At the latest change I drained out the Castrol 5w-40 only because it has been in for a year, very few miles. Put 0w-40 back in only because I forgot that it is no longer LL01 rated. Had good luck with it before.

Although the recommended weight for North America was 5w-30 (It was 0w-30 in Europe), it might be interesting to note that the LL-01 approved list does include 5w-40 and 0w-40 oils.

LL-01 Approved Oils

Here in Europe, where we're blighted by BMWs with diesel engines, BMW switched from LL-01 to LL-04 in 2004. LL-04 doesn't block diesel particulate filters but is otherwise pretty much the same, or so I've read, and both are approved for E46 petrol engines in Europe. Indeed, our BMW dealers use LL-04 when servicing.

LL-04 Approved Oils

There are 35 0w-40 LL-01 and six 0w-40 LL-04 oils in those lists. I'm not saying anyone using a non-approved fully synthetic oil is necessarily wrong to, especially if not leaving it until BMW's 25,000km service intervals between changes. I just know I don't much about oil formulations, so personally I favour using approved oils when everything else is equal. Either way, it's nice to know that 0w40 as a weight has the green light from BMW even if it's not their primary recommendation for the E46.

Much like many here, I use mobil1 0W-40, don’t live in a very cold area. At every oil change, oil is a dark yellow.

When I started, it was syrup at every change (3k mile intervals)

EDIT: I should add that I am at 208k miles now.

May I ask you what oil change intervals you have at the moment?Your engine in in that critical age/mileage that soon you gonna face oil consumption, and Castrol gonna play its significant part in that.
My E46 has never burned or leaked a drop of oil. I change the oil every two years which in reality, adds up to about 3-4k miles. Not all E46's burn oil.
