While I know it's been discussed, I've not been able to find a firm answer. If I missed it, I apologize now. But do we know why it was changed mid year? Living in Florida, I'm not thrilled with the idea of 0W-20.

 

I think it changed around January of last year because that's what they filled my new engine with.

 

It's just my suspicion that BMW did it for corporate fuel mileage. That's been the case with other manufacturers in the past. I'd lean towards better protection in the warm temps of the South. If it's truly a flow improvement that's one thing...I just have my doubts. Anyone informed on this?

 

It's an interesting question. In 2001, BMW changed the oil for the E39 M5 from 10-60 to 5-30. When I picked up my 2001 a few years ago it went through a quart every 300 miles. I changed back to the old 10-60 spec and have never used a drop since.

Even more interesting is that BMW later recommended that all E39 M5s use the the 10-60 specification. You are right to question the switch.

I live in Florida as well and oil is a very important component of the cooling system.

 

I do my own oil changes....never had a service at the dealer. I put 5W-30 MINI oil in there just like the sticker says on the engine cover!...yes it’s still there! :-). I know they recommend 0W-20 now but there’s absolutely nothing wrong with going with the original spec., especially in FL!

 

I figured I wasn't the only one thinking this. Odd that there's not been a definitive answer. I'm sure I'll stick to the original grade, unless there is strong evidence to lead otherwise.

 

I've done a couple of changes using Mobil 1 10W-40 that I had left from my R56. Didn't cause a problem.

 

It's not that I have concerns anything will happen. I just prefer the thought of it perhaps running a bit cooler and less wear over the long haul.

 

Yep they changed the oil viscosities dependant on the newer engines. Some people will still use other viscosities, as long as it LL-01 you should be fine.

I guess I'm not "getting" the change two years into the new engines use in the MINI. Better for the engine or just CAFE standards thing.

 

Just a new standard based on the engine. Think most of it's for emission and maybe cafe standards. But I just have an internal flyer from MINI / Shell/Pennzoil and its about efficiency.

 

Thanks for the feedback. I'm trying to make a decision with "my" first oil change.

 

Welcome.
