Whos running Mobil 1 0w-40?

+1 even with exclusive city driving.

But the only comment I will make about M1 0w-40 is that, the engine doesn't feel "strong" when you floor it. I don't know whether this is largely due to enhanced flow rate compared to 10w-60, and the engine is revving a lot freely. This is my initial 300 km observation.

The only mother difference ive noticed is the cold start up is quieter. Otherwise, feels the same

Yes, cold start even quieter with the cold start turned off (tune). The other thing I also noticed is the kangaroo hop at start up and the hesitation is no longer present.

That's because you are in kangaroo land my friend !
BTW ...how are you ?

I am well P. How's the car going? I am trying out M1 over winter/spring to see what the readings are. I am beginning to do a lot more short trips, and my driving is mainly city. Hope all is well at your end

Thank you...My car is running just perfect with EDGE ,hoop to keep it this way .

Anyone noticed, but the M1 0W-40 is burning quite fast in my car... checked for leaks but nothing. I put in M1 around 6k km ago (approx. 3700miles), made sure it was filled to max line. After maybe 3-4k km later, i was approaching minimum level, so i topped it up to max again. Now, the oil level dropped down to the middle again.

Is it me, or does this thing burn FAST. Or is it suppose to be like this since i just switched over. Used it in my tuned 335i (which is notorious for burning oil due to turbos and tunes etc) and it never burned THIS fast.

I overkill my oil changes, car due for change when it hits 7-8k km. Will do a blackstone report then as well.

Common when switching to a lower weight oil. A lot of us initially encountered excessive consumption when switching to 0w40 but it seems taper off. I now burn a little less 0w40 than 10w60. I have also been adding mos2 by the can so that might also be helping with the consumption, but it sure as hell makes a cold start sound less brutal on the motor.

Lead reading has gotten better since switching to M1 but oil consumption has gotten progressively worse

For you guys burning too much oil with Mobil, try a high quality 5w-40 LL-01 approved oil instead. Mobil tends to be on the lighter side of 40 weight oils. I switched to a 5w-40 and it definitely helped.

+1

Mine has not burned anything significant. My oil gauge is still pegged at max. Only driven about 800 miles.

Mine has been stuck half way between max and half, and it has been 1k km since my oil change to introduce M1 0w-40. I put 9 litres as per my regular change.

I read in the owners' handbook, using a diffrent oil to 10w-60 may not give an accurate oil level reading. Why would that be? Oil is oil, and does the sensor pickup the different viscosity of the oil. I think think this another BMW BS about oil

[REV1]

^ The dielectric constant of the M1 vs TWS will be different so the oil wear/quality sensor will probably not read correctly. I'm pretty sure they apply a small voltage and read the Dielectric constant to determine oil wear/quality.

As far as oil level it shouldn't make a difference unless its more than just a simple level check.

+1. I have about 1000 miles since the change.

[kaede]

what's wrong with mine, it dropped by another level today again guessing it might be the weather warming up as well? During the cold winter'ish days it still drops, but not as fast. Will give it a go for the next oil change (have around 6500km on the oil, will change it out when it is around 7500km) again and see if it is still that bad.

Checked for leaks again just to be sure, but nothing. =/

I saw M1 5w-40 in the stores and it's a semi synthetic oil. I don't know what it will do to the engine given that we've always run fully synthetic oil. 5w is still better than TWS 10w, but what we're trying to counter is the cold start bearing wear.

One thing for sure, the M1 0w-40 warms up a lot faster than TWS. The other night when I started the car the oil temp was 16 Celsius, and in no time it was 70 Celsius. With TWS it would have taken me a good 20 minutes of driving to get to anywhere close to that.

I am doing well since my change to M1. It's been 1k km and the oil level is ok, although I was surprised it wasn't near maximum given that when I put 9 litres with TWS it shows that mark once the oil level is read.

I am wondering more than the bearing themselves, whether the oil pump is a contributor to this bearing where. I've noticed with TWS, and when cold, the cold start is extremely rough and lumpy. With M1 it is a lot smoother and the engine revs freely.

Experts out there, any thoughts on this?

Got my 2nd oil analysis with 0w40. This time running 4600 miles and 1 track day in colder 60 degree fall weather.

My first analysis was with 0w40 mixed with 2 quarts of Redline 10w60... ran 1 track day on that with 100+ degree summer weather.

So far looks good! Lead #s are falling... not that it was originally high anyway.

Next analysis will be a mix of Mobil 1 0w40 with Castrol TWS.

Just to clarify I would never suggest anything but a full synthetic. Pennzoil and Motul both have great LL-01 approved 5w40 oils. Also, the 5w40 Pennzoil Euro I use warms up just as fast as the Mobil 0w-40 did. I agree the TWS 10w60 took forever to warm up.

I've never seen moly levels so high in any of the reports here. The numbers look good!

The moly is due to the Redline motor oil. That's why the level dropped a lot with straight Mobil 1 0w40.

Pretty happy with my analysis so far!

[dereksM3]

Any reason to not just run strait Redline? I'm running the M1 but contemplating switching to 0W-40 or 5W-40 Redline.
