People can put cooking oil into their engine, no one cares really. Follow the instruction from BMW, don't be a fool lol...

My car will always be under warranty so I'm not that fussed, plus my car is garaged so it never gets that cold - still as I say a lighter weight oil seems to make sense if you aren't tracking....I'm just not going to risk BMW voiding my warranty should my engine go tits up.

Even if you live where it's always warm, M1 0w40 has advantages over TWS there too.

In North America, BMW has decided that TWS isn't made from unicorn tears and that the motor will happily run on tons of other fluids.

I think if the UK market allowed a "thinner" oil I would probably go for it too.

I understand you guys delima, you want to run it but it is not yet approved. It stinks that they cant all come together and agree on something. I will never be convinced that different areas of the world require different oil.

Its probably something to do with the exclusive contracts that Castrol have/had with BMW as being the OEM fill oil and the only recommended oil.
Maybe that contract has expired for the USA market while ours hasn't yet.

I did a switch, I noticed better throttle response, a more eager revving engine, and a markable improvement in mpg (1.7mpg on my last tank, i'll give another update on this current tank once it runs low just in case it was a fluke, so far the display reads similar to the last tank, which read .6mpg higher when I manually calculate) And yes, the oil runs cooler too, I can do a couple WOT runs and the oil won't pass the middle mark, whereas the TWS would heat up slightly above.

I had a cocktail of Redline 0w40 and 10w60. It was a mix of 3 quarts 0w40 and 6 quarts of 10w60 Redline. The Redline oil really made the car feel sluggish compared to TWS and it didn't really want to rev. I tried to make the 10w60 thinner by mixing the 0w40 in but I probably didn't put in enough 0w40 to really make a difference. I dumped my Redline oil with only 200 miles on it (wasted my money on that!) and got Mobil 1 0w40.

Walmart was sold out of the 5 quart jugs and I ended up cleaning their shelves of 0w40 with 9 single quart jugs... it cost a lot more but still cheaper than any auto parts store.

Cold start up I don't really notice any difference. It still takes a while to warm up. Gas mileage I don't notice any change. The difference I could definitely feel is the speed the engine revs now! The engine feels so much more responsive and it wants to rev fast. The RPMs climb much faster and more willingly than on the Redline. I took the car to autocross yesterday and the car felt great on the 0w40. Coming out of corners, you get instant throttle response. The willingness to rev fast really makes the car feel alive.

Lesson learned ... don't use Redline 10w60!
In cold weather, I can def tell that M1 heats up significantly faster than 10W60. Maybe it's not as apparent as warm weather. But during my 20 mins commute to work, 10W60 would barely reach 210F as I pull in the parking. M1 heats up faster to the 1/3 mark for sure, then it takes as long as 10W60 to reach 210F. That's still absolutely worth it to me though.

Plus you can't beat $26 for 5qt jugs. ~$50 for oil per oil change? Win

Yes, I am sold on the 0w40 at least compred to Redline 10w60. Compared to TWS... it's a small improvement. I'll see how it does. I love the willingness to rev!

The weather has been about 35-40 degrees F in the early morning here so it's cold but not freezing. Warmup time is about the same for me. I've only been looking at temps going to 210 so maybe it's as you say - where the temps go up faster in the first 1/3 and then take the same time to 210.

I'd really love to see some oil analysis on the 0w40. Better yet someone who has lead/copper in their oil before with TWS and is now gone with 0w40. No one knows yet if 0w40 helps the rod bearing problems.

Actually, talking with Kawasaki, he's seen where people that have had high led content with their last 10W60, switch to 0W40 and the lead went to 0. I don't know which member that is, and the bearing has still been worn, but it seems to help.

During my last oil change (Liqui Moly 10W60), my lead levels were at 8 ppm (twice in a row actually). I need to do about another thousand mile, maybe less, and I'll send my 0W40 out for analysis. Will definitely post results.

You would need a decent history of UOAs from the same vehicle in order to draw any sort of conclusion. There is something known as particle streaking that can cause a false-high reading. If you talk to the guys at Blackstone, they'll tell you that far too many customers panic when they see an elevated number in a single report. You should use UOAs to establish trends and to monitor how a particular oil is working under YOUR circumstances.

Where's the drive for M1 0w-40 come from, have any big workshops/tuners recommended it yet? To me the US bulletin says 10w-60 or 5w-30 which seem like chalk and cheese. I haven't even heard of anyone using 5w30 yet.

What would be best for a DD track car? I've also had issues with 10w-60 and bearings on past S65.

In the UK, the S50 M3 rod bearings seem to be more prone to failure than both S54 and S65 engines.

S50 runs 5w30 or 0w40 and only revs to 7,600 rpm

I'm sticking with 10w60 Edge TWS

The bulletin says you can use TWS or BMW's 5w30, or any LL-01 approved oil. M1 0w40 is an LL-01 approved oil. The BMW 5w30 is a very thick 30 and behaves like a 5w40 in operation (HTHS > 3.5); it's not a resource-conserving 5w30 like you're thinking of.

M1 0w40 is Mobil's halo product. It's marketed as a streetable race oil and you will see that the specifications are almost unmatched by any other off-the-shelf oil, and even many boutique oils. You can absolutely use it for a DD that gets track time!

Dan,

BMW genuine 5W30 is actually not recommended for the M cars, only the Castrol Edge 5W30 (I think it's a diesel oil) or LL-01 or TWS is recommended for the M cars.

Until someone makes a better oil, you simply can't beat M1 0W40.

Unless forced by the NHTSA (National Highway Traffic Safety Administration) as a safety issue, automotive corporations will not issue a recall and their accountants will advise that fighting the few issues in court is cheaper than fixing an entire fleet of vehicles.

Switched to 0w40 for the winter and can attest to the free revving nature and quick warm up over tws. Will be switching back to the 10w60 for the summer and track season.

Sent my sample of M1 0W40 with 5k miles on it to Blackstone. Will be able to compare it to the last 2 10W60 samples. Stay tuned

It'll definitely reveal new info as you have the early bearing sets.
