Why are some dealers using 0w40 and some using 5w30
I guess they buy it for different prices and charge the same
Why are some dealers using 0w40 and some using 5w30
cool, so, in theory, it makes little difference whether it's 0w40 or 5w30
and what of the OMGTURBODIESEL text often found on some cans?
Also, is there *really* any difference between 0w40 and their 0w40 OMGTURBODIESEL range. Both are Fully Synth, what else do they add to the TD oil, if anything.
Big myth



Still going to happenI like to know that the engine is in good shape. If I want to do any oil change in 6k miles because of upcoming large mileage, and for my own peace of mind, then that's what I'll do. I really don't need an internet forum to validate my decision, thanks.
However, if you want to continue derailing, please, carry on.
Have we slipped into a religious discussion? or you on about engine flushing?![]()


I'm not happy. It's got me worried. What oil should I buy?
Tempted just to go to BMW and bend over as I need it ASAP.
And I was really impressed that it hadn't used any oil.
But now I'm concerned that its empty after only 6500 miles :/

The low level light comes on after it's only used a litre? I thought it would've meant you've used a lot more.[TW]Fox;22545969 said:What the heck? It just needs a top up, calm down. Go and buy some LL01 approved oil - Castrol Edge will do - and top it up.
Only one topup in 6500 miles is exceptional - stop worrying about it. It's not 'empty' it just needs a litre of oil!![]()

Ah yes, it does say top it up at your convienence (when you next fill up).[TW]Fox;22545987 said:Yes, its not an OMG WTF light, its an 'Add 1 litre of oil when its next convenient' light.
All of this is described in your owners manual
We are talking about the light that comes on after you switch off the engine right?
CheersThe oil level warning light is just that, a level light (unless it was red... in which case you're in trouble)
Castrol Edge 5w-30

Point still stands, that dipstick is ****.
Well now that I know there's a low level light, I needn't bother to check it again![]()
