Given how long the car spends bringing the oil up to optimum operating temp, I think it's advisable to go with M1 and protect the bearings. You don't spend the same amount of time at top rpm (8000>) to benefit for TWS. Street driving with an occasional spirited driving and regular oil change around 5k-6k kms or 12 months, M1 makes perfect sense.

I am changing today to M1. Wish me luck guys

I just changed to M1 too. I took a slightly different route I did the 6quarts of 0w40 and 3 quarts of 15w50 to see if consumption that some people are seeing with M1 is reduced. With about 200 miles on the oil I can tell that: it does indeed heat up faster, oil temp stayed about the same, does rev slightly quicker. Will calculate MPG soon but it seems to be about the same. Also note I threw in a can and a half of MOS2.

Cheers!

Glad it is working out for you. You will see less consumption with the 15-50 added in. Consumption will be higher with the lighter oil that is just the way it works. It will get better after a oil change or two so dont be alarmed if you consume more after just switching.

the consumption on my first M1 fill was pretty high. I think I added almost 1.75L of M1 in 5k miles. Mostly city driving...

On Edge, I noticed with my current city commute, I still added almost 1L of Edge.

That mos2 is some good stuff.

[haparide]

No doubt! I originally tried it about 3 months ago in my 5.7L Tundra (uses 0W-20). I can't even tell the darn thing is running anymore its so freakin quiet. We'll see how the S65 likes it. So far so good.

I have added 2 Ltrs over 5k km between oil changes with TWS 10w-60. So I don't thin 1.75 is high with M1. My 2c.

My observation is also that if you perform your break-in runs fairly hard, you are less likely to burn oil.

I've owned 8 new cars and 3 new bike, and I'd always take them out late at night, warm up the engine to operating temp, and slowly build the revs to redline and lots of engine braking. It's not scientific I know, but my cars/bikes simply never needed engine oil top off during an OCI.

I have heard this a lot as anecdotal evidence (hard break in linked to little/no oil burning). Seems like break in is a personal thing with opinions varying. I just wonder that if doing a hard break in is truly the way to go, why does virtually every manufacturer recommend some kind of gentle break in? They could simply not mention any specific break in procedures and have people drive as they normally would immediately. But manufacturers go out of their way to spell out specific procedures to adhere to during early engine life.

[Leonardo629]

I think one of the reasons most manufacturers don't even have a break-in guidelines is because they don't want to implying going over the speed limit on most roadways.

Think about it, if you have to redline your M3 in the first 3 gears, you'll be breaking traffic laws whether you are on a local street or on the highway.

I've performed the below break-in procedures religiously on all my new cars/bikes, hell...I even took my DD '13 Accord 4yl out late at night, and introduce the motor to the measly 6800rpm redline. And My accord does not burn oil during the 10k OCI.

For the 1st 150 miles I take it real easy never exceeding 75% of the redline, lot of engine braking.

From 150 to 250 miles I try to liven up the process by introducing brief spurts up to 90% of the redline, lots of engine braking.

250 to 600 miles it's spirited driving, but still making sure to keep the rpms fluctuating & I routinely take it up to close to redline without hitting the hard limiter.

600-1200 miles I try to redline the motor whenever I can and lots of engine braking, and when I hit 1200mi, I bring the M for the M specific sevice.

After 1200 miles like everyone else, the break-in is done and you can drive your car however you want.

**No steady rpm, and ever increasing rpm peaks

I understand why a manufacturer wouldnt say "go redline the car as much as possible for break in" for the reasons you stated above. But if there were simply no break in procedures stipulated, then that would imply to drive the vehicle like you normally would from day one. Instead, BMW (any most manufacturers) specifically state not to exceed certain rpms and throttle positions for a specified period. There must be a reason behind this.

Have to give those poor bearings time to get used to the idea of wearing out in 20k miles

[Gumulri]

I get bored so I have changed to 0-40 m1 again. it really giving some power and fun to drive with that oil way cooler temperture than 10-60 tws.
I just got expired from extended warranty. So I gonna go with m1 for now.

[JRV]

Guys were any of you ever concerned about how long it takes for the oil to warm up in these cars? I was always dumbfounded as to why compared to my jeep and my wife's Merc. So I had a 2014 535i x drive for a week which I returned yesterday. Let me tell you that car was worse! It takes forever to get to temp. Makes my car on TWS seems quick and normal. That's all.

So I'm intrigued by the M1 0w-40 oil.

So much so I'm wondering about using it in my S54 too. Anyone have any reports on usage in an S54? The cooler running temps are a big plus as my S54 runs hot (I do track it).

I did a search and there were a couple of posts on Amsoil in this thread but nothing specific about their 0w-40 oil. From what I can tell, it isn't BMW LL-01 approved, but it's late and my eyes are getting sleepy...

Good thread. Love the oil analysis to back things up. My E90M3 comes off warranty in August so I won't be changing oils until then.

I ran M1 0w40 on track on a very hot day (100+ degrees F) and it holds up.

The lower temps with 0w40 is mostly in normal driving. The 0w40 temp goes up same as 10w60 on track. What I have noticed is that it cools down faster during cool down laps though.

I have no idea about S54. Do some research on it. The S54 is not really the same so engine oil needs could be different.

I have been interested too in the 0W-40 for the E46 M3 and have been following this thread for some time. However I don't believe our (S54) bearing clearances are AS tight so people are less inclined to switch. Also, there have been enough reports of people running over 100k miles and even 150k miles with bearings coming out looking better than nearly all the ones I've seen here. I want to believe that the 0W-40 will work but until someone takes the risk with documented oil analysis, oil pressures, and removal with pictures after significant miles, the 10W-60 will be the oil of choice. I would say a lot of the decision has to do with climate as well. In Southern California there is no such thing as winter so using a lighter oil for colder temperatures doesn't really make sense here.

If Kawasaki can convince me otherwise to switch after looking at the e46 M3 bearing clearances, I'll consider it, but until then, I'm sticking with the spec'd oil.

Update: 1200 miles on this oil and it has not gone below the full mark. I'm attributing this to using 3 quarts of 15w50. Still no noticeable improvements in mileage but as I stated before the oil does heat up much faster. Overall I'm very happy with the switch!

For those looking for something a little stouter for the coming warm weather NAPA is currently having a sale on the superb Mobil1 5w50 oil. Check the specs!:



$6 a quart:

Buy 10 and get a $24 MIR:
https://apfco.net/secure/R8235W/Content/OfferForm.pdf

My plan is to do a 50/50 blend of this and 0w40 for my next OCI since the weather gets mightyyyy warm out here and I do drive it hard.

Also if you need filters the best deal I found is a 4 pack on ebay that comes out to $12.50/ea shipped.

I've been running it in my N54 135 for a couple of years now and I have great results from it. The price is nice too. I'm still trying to figure out if I'm going to use it in the M3 I just picked up or not........hmmmmmmm

Hot day, hot oil, high RPM is when you should LEAST be thinking about switching to a thinner oil.

A 0w-40 is probably a better choice for an S54 that never sees the track. But switching on a tracked car, especially without an oil pressure gauge, would be very foolish imo.

I would suggest reading this through fully before changing off of OE specs. http://ferrarichat.com/forum/faq.php?faq=haas_articles

Thanks. Good read. Just grasping for anything that will get the temps down on the E46M3 (already have the C&R rad and oil cooler). The E90M3 ran just fine at Chuckwalla this past weekend. Oil temps were a smidge above the center line.

Damn, that was intense.

The writer seems to suggest thinner oils in just about every scenario. He even supposedly goes off factory recommendation for his Enzo with a lighter weight oil. Seems like the only time where he suggests (really more like condones, or leaves vague that it might be necessary) a higher weight oil like 10w-50 or 10w-60 is for racing purposes or specifically hot track days.

Also he mentions several times that synthetic oils of different brands should not be mixed. Interesting.
