Beng, d list is as follows:
3. LL-01FE; &
There is no difference btw LL-01 & LL-04 except LL-04 has lower sulphur content (which is suitable for modern diesel engine with particle filter).
WTF is BMW LL?
"BMW Longlife is the BMW spec for oils suitable for its range of cars. It's important to use the specified oil for BMWs because its engines are among the most sophisticated in the world. If you just use any cheap oil from a petrol station shelf, don't complain later if you have higher engine wear, higher fuel consumption, and end up with a sludged-up engine. See http://www.castrol.ae/TDS_SDS/other/...BMW%20LL01.pdf
BMW LL-01 (from 2001) is the specified oil for current E90s. So we don't need LL-04 yet and shouldn't use the older LL-98, which I believe can include Group III mineral oils in the blend. LL-01 must be a fully synthetic Group IV oil blend. Group IV is polyalphaolefin oil or PAO for short."
i've read somewhere that LL-04 oils should not be used in BMW spark ignition engines outside of Europe. Think it was a US forum that said the fuel grade in the states isn't suitable. Dunno if this also applies to us in Asia. but i did note that my car manual states for me to check with local BMW dealer on appropriate engine oil. I am guessing that no specific oil spec was mentioned since LL-04 is only applicable in certain regions, and the same manual is distributed across Europe/asia. It does state that LL-01 is a suitable alternative regardless.
Thought of asking PML CSAs, but I haven't met any who seem technical/bothered enough to pay attention.
davidtch, the document you posted, i've read it before too. It also seems to say LL-04 oil was designed with improving usage with diesel engines.
If it helps petrol engine emissions, i'd be happy to use it. Also, lower sulphated ash in LL-04 oil sounds good to me. Less deposits left behind. but i wouldn't touch the stuff till BMW Asia/PML state clearly that our fuel grade in SG meets requirements for LL-04 in our engines.
PML uses castrol formula slx. no idea what the tech specs of this oil is, i'm guessing this is the "workshop only" oil provided by castrol. Castrol has so many different SLX products in different regions, its frustrating to research. i'm just hoping it's the German Castrol the US guys all rave about.
yup, pml uses castrol slx, which is not longer available in the market. I was told by pml and other independent workshops. slx could probably be still available in Indonesia. But really hard to search on the net.
some rumours that pml uses petronas oil. For that reason I think petronas oil is not bad.
anyway, i have tried 0w-40 mobile 1, engine felt lighter but torque not restored. did smell the oil, it is quite odourless unlike the bmw long life oils, which has a characteristic chemical smell, i think they have special additives.
