Although I do OCs (using a MightyVac) in my 2005 E46, once in a while i take it to the dealer do to a proper "drain", and they have always used BMW 5w/30 and Mann filter. But this last time the receipt shows 0w/30 FE. I emailed them and they say BMW back-specc'd 0w/30 FE for this engine. I just cannot find any proof of the FE being ok for this engine AND i just don't want it. And for the first time EVER, the yellow oil light (NOT RED) came on AFTER I shut the engine off. (this was after about 3-4 weeks since the O/C at the dealer). This is BMW speak for "watch oil level but no need to add immediately"- it remains for a few seconds after shut off and then goes away. I added some 5w/40 and the oil light never came on again BUT I cannot but think that this has something to do with the 0w/30 FE.
I have owned the car since 12k miles and always used 5w/40 in summer and 0w/40 in winter, except for the occasional BMW 5w/30 at the dealer. (I let the dealer change it whenever they have coupons OR every 4th DIY change).
Anyway after a string of emails back and forth service advisor said I can bring my own oil in the future... They don't even stock the 5w/30 oils any more.
SO, what do you guys think? were they correct?
(the 0w/30 FE is still in the engine. And it is not SUPER hot yet....I am just gonna keep it until it's time for the next OC and this time it will be a DIY so going back to 5w/40)
