BMW adds 5w30 to M engines oil list

But is there any cast iron 100% proof that the replacement s54 bearings run more clearance than the originals? Or is it an urban myth?

The Z3M S54 didn't have the bearing recall, it just changed from 5w30 to 10w60tws with much success.

Looks like the diesel oil is eve thicker.

There's horse power in oil. We're not talking crazy amounts, but enough to win a race or not.
My 60-130s were slower with the 5w40 given close to the same temp, humidity, etc.
I also noticed higher oil temps (+10 degrees) when compared to the 5w30.
I'm assuming that the thicker oil was slowing down flow going through the cooler. Just an assumption.

I'm no oil expert, but as far as the high antiwear properties, I believe that the Mobil1 TD 5w40 would be a contender in oil substitutions for the S65.

Thinner oil releases heat easier than a thicker oil.

True, some testing was done (on different engines obviously) on Bob is the Oil Guy and 2% hp difference given the kind of 2 level changes in viscosity we're talking about (10w-60 to 0w-40). Wouldn't be surprised if worth 5-8 bhp on our cars.

Great news financially with the 5w-30 for interim oil changes. I just called my local BMW dealer, shot them the link (http://www.bmwusa.com/Standard/Conte...ngineOils.aspx), and they said they could do it for $97.50. Heck yeah!

[PandaM3]

Just called Motul... after they spoke with HQ in France... they recommended 300V 10w40 or 5w40

They said technically the 8100 5w40 is BMW LL01 approved and therefore won't void warranty however the 300V will offer improved protection especially around the rod bearings

Between the 300V 10w40 and 5w40 they recommended 10w40 since it will stand up to longer oil change intervals however 5w40 will have better flow at start up

That's pretty good. Depending on the price of the oil, that's only about $30 labor

$30 for them to do it, I sit there watch TV, and drink as many K-cups as I want. Count me in

Take a look at the oem's that spec the 0W40 for use in their engines, it is a pretty impressive list....... Porsche (all models including the GT3/GT3RS), MB (all AMG cars), Nissan (GTR), VW/Audi (Numerous models including the R8 V10), Chrysler (all the SRT models........ And there are still more!

Don't worry the S65 is not an engine that puts super high demands on engine oil as we have seen from UOA's. Use the 0W40 with confidence, it really is a great oil!

thanks for the response...i should have been a little more clear...i have no problems running the 0w40 - the weight doesn't even matter since im in socal and we don't get any snow. I was more asking about running a thinner oil under temps at the track...so basically hotter than your average conditions when driving. I've heard conflicting things such as "if you track your car often, stick with 60, if not 40 is good". that part has me confused....

[SuckaGDog]

Since everyone is throwing different oils into the thread, I'm wondering if anyone has considered the Mobil 1 5W-50 oil? The same oil they use in the Lexus LFA. One of the engine builders mentioned it over at M5Board. It isn't LL-01 approved though, but it is approved for BMW diesels? lol. I'm assuming without the particulate filter.

i'd use the 0W40 on the track without issue. If your car is a purpose built track car then maybe a dedicated race oil is in order, however with a mix of street and regular track use the 0W40 will be just fine!!!

Ok thanks!

Why were some ppl saying that 0w40 wasnt as good on the track? Im assuming that ppl were thinking that it would be too thin for protection under hotter temps but my thinking is that this oil is a better protectant under harsher conditions. I will give it a go.

I think the reasoning as the oil gets very hot, the oil pump might not be able to keep up (correct me if I'm wrong).

Kawasaki tested the oil up to 230 I think and said the pressure was fine at that point. You'd have to ask him.

Like I said, I've beaten mine pretty good and the 0W40 doesn't act any different than the 10W60 did IMO.

Fuel pump or oil pressure?

Does oil temp not get hotter than 230F at the track? Granted the needle doesnt move much but is that even accurate?

Sorry corrected. Oil pump.

You'd have to ask Kawasaki yourself. I don't think it'd be a problem. I know in my case, M1 is more than adequate for the temps I see.

Considering the turbo BMWs run oil at "normal": 240F, with 5w-30, 0-40 Mobil 1 should be a non-issue, even if they don't hit 8k+ rpm.

And the turbos are cooled by the oil which nukes them to well over 1,000*F briefly. Turbos are very hard on oil.

The 0-40 can take the 275-280 temp but I was hesitant on the recommendation for it because I do not have pressure data at that temp. I have run it to 230 many times and it still has 35psi so I would guess probably 27-28 psi at 275, which is just fine.
Start getting down to 20psi and it starts getting skechy, the bulk of that type of damage comes from exiting the track and lugging the motor back to the pits.

hmm, but now that BMW is coming out with the 5-30w oil recommendation, can we assume that running the M1 0-40w should no longer be a concern?

The other question that I have is for folks that already have a high copper/lead count from their oil analysis, would switching to the thinner oil at this point be potentially more harmful than good? I am thinking that since the bearing is already worn to the copper, this would indicate a bigger gap/clearance between the bearing and journal. Switching to a thinner oil at this point would have a higher likelihood of a sudden lost of oil pressure due to too much clearance? Can the expert chime in on this?

Just bought 2 5-qt jugs of Mobil 1 0w-40 European Car Formula at Walmart for like $25 each. Now it's sitting next to the 9 qts of Castrol 5w-30 I originally bought until we can reach a consensus (thanks BMW) on which one goes in the M3 with 15000 miles on it.

The 0w-40 is LL-01 approved. The 5w-30 that BMW recommends is not. It's LL-04.

If you change at 7,500 intervals, you should be fine with the 5W30.
