My X5M came with the oil filter cap that doesn't have the drain plug.
They are both the same price.

I believe it's a different part number for the x5m ironically but should still fit, there's 2 part numbers but I can't tell a difference, just provide vin at checkout to make sure it'll fit (should still show up as fits even if yours didn't come with one)

I use Pantere 0w40

And yes 11425A34A34 is the cap with drain plug.

Thanks.
So is the oil filter part # the latest updated oil filter?

Filter hasn't changed as far as I know. But this part number includes the new drain plug and o ring.

Correct filter hasn't changed but there are other part numbers for different models other than m5 for the kit and and the filter cap drain plug

For oil filter kit there is one that ends in c42 instead of c43 though not 100% sure which car that's for.

The 63 motor should all be the same filter house/filter. They're the same on my X 5 and M5

I could have sworn a few months ago that BMW stated they were coming out with a revised oil filter for the V8 engines. Maybe I'm mistaken?

I too would liked the answer to this. My answer when I used this great racing oil was "every two track events", but I don't know what other people do but I'd like to hear.

Did you notice a performance change using this stuff? My car feels/sounds like it labors at the end of the day.

300v is a racing oil designed to save the engine from the rigors of track use. Power loss isn't a real effect, but it does cushion the bearings very very well.

I put 5w-30 redline in my car, and I'm nervous I should have used 0w-30. I live in the San Francisco Bay area, and during winter, it never gets colder than 35 degrees, and that's in the middle of the night when I do not drive. During the morning and night time the temp averages around 45 degrees. Am I worrying unnecessarily?

Cheers!

[pbonsalb]

Yes

[Ropes]

The 0 vs 5 is for cold pour point and it is not that cold in San Francisco to worry one way or the other. Driving in the temp is irrelevant because when the engine is up to operating temps the oil is the same temp as it would be on a 100+ degree day. The second number is for when the engine is warm. I personally use 5w-40 because the 30 I feel is too thin and geared more for fuel economy than protection.

My own personal thoughts and feelings to the side...
(and the fact that most oil threads on most sites are banned due to craziness).

Do you have data that suggest a 5W-40 is too thin and doesn't protect the engine as well?

And, doesn't the oil that gives you the best economy because of the lowest friction also give you the best protection? Once it gets too thin, of course the lubricity breaks off, but then fuel economy goes down because the parts are rubbing together. But where is THAT number? And if thicker is better for protection, why not a 0W-50? Or just a straight 60 weight?

Just asking. Want to see if anybody really has any NEW data, or just doing it by making it up.

To Me there is 2 critical parts to longevity in a motor.

1. cold starts.
2. high temps,, and enjoying the shit out of it.


this Is why 0w (for me) in Canada is great, was only 2 degrees this morning Celsius, and 18 during all day. 0w-30 perfect.

Now would I change that in hotter climates. Probably. 0w-40, 5w 40 etc.

But to each their own.

Meh,

Do you REALLY think that the difference in hot oil temps are that much different in Mexico vs. Canada when fully hot? The data says not much. And if it is, its mostly due to inadequate oil cooling in the car. (ok, I'll admit that SOME of Canada - Ice Truckers, etc. - are out of spec, but not much).

Hotter climates (other than the extremes above, Death Valley, etc.) rarely push oil temps. They're 190-215F if you're driving in 50deg weather or 105 if the oil cooling is right. And it is on this car (as far as I can tell in stock form).

I read bobistheoilguy sometimes. Lots of debate about oils.

I Shall reply in a respectful tone if I may.

I do notice over the 4 years of owning my M5, and 12 years of of owning my 335I, those are just my BMW vehicles, I will not go into Gm's and my Benz"s ( plural).... I do believe a 40 oil will be better in hotter temps.
But again , my friend Shawn - to each their own. it all good, We are all here to help each other !....
I say this cause I can feel the engine and smoothness when I drive over 10 + cars with different oils etc.

[Danny D]

my old man 72 drove his own 99 Silverado - yesterday told me.
Men this thing is running smooth what did you do -
I told my 72 dad I changed the oil to 0w30 mobile 1, some motor mounts and gaskets, he was on cloud nine, for his old truck -- I was proud.

I cast doubt not to insult, but to provoke thought.

But, in 20 years of running cars on the track, a 40 weight oil outperforms a 30 weight oil in oil analyses - but only when the car has shitty oil cooling. We had a GIANT project at (what is now) GTRLife, used to be NAGTROC. The differences basically came down to who had better oil cooling. The stock cars needed 40 (and even 50) weights of racing oils to make good numbers. The ones with accessory oil cooling needed jack - nothing - nada. Factory fill. But all of them would have lasted 100,000 miles - TRACK MILES. Without breaking a sweat. The data just isn't there. You may feel something different, but it isn't borne out in the long term data.

What we found, over multiple cars, multiple tracks, multiple brands, was that the OEM RECOMMENDATION trumped basically everything unless the car had a fault. And the one thing that demonstrated this, was on oil temp gauge. If your temps were too high, you needed either better oil, thicker oil, or better oil cooling. Better oil cooling was always found to be best. There were plenty of cars that failed that in our opinion (the new C7 was a particular offender). The ones that didn't get the factory option oil/trans/diff cooling didn't do well.

But again, as you say to each his own. You say you feel something different. Okay. I can't say that. A good car with proper cooling with good oil runs the same to me at the end of an oil change as it did at the beginning. When it doesn't, it needs valve work, head work, or bearing work. A thicker oil can temporize the situation, but liquid chemistry is only a band aid.

As pbonsalb says, and bobistheoilguy has been around now, FOREVER, there is no settled opinion about this. Hundreds of thousands of oil changes, and oil analyses, and the trends are...drumroll please.... read the manual. When you deviate too far from it is when things go south, mostly. Or the car is ancient. Or both.

I do think BMWs specs have change for the current evolution of the motor not because the bearings and piston rings have changed but for fuel economy purposes. I think 5W40 used to be the spec but it is now 5W30. Maybe oil cooling is improved? I don’t track so I don’t see temps get “too high” which for me would be 275+.

One subject matter I would like to explore more is LSPI with low viscosity oils. The cause of LSPI is still debated — there are several.

You are right and wrong for the same time. The old spec for M cars was this:



And we used it in our giant project. Decent oil. Really thick at temp. Car had to have slightly loose tolerances to circulate good at startup/warmup.

As oil cooling got better, and tolerances got tighter, the fuel economy was being impacted negatively by pumping losses and drag on the components. I don't use amsoil, but they sum it up pretty well here:

https://blog.amsoil.com/what-happens...and%20deposits.

BMW began speccing the oil down as thinner once they got good cooling in all the M cars. A good 30 weight is what has been used in most american V8's for eons. Once BMW got good cooling, that's what they started using.

On top of THAT, think about it....If the thinner oil gives better fuel economy, isn't friction going down? Isn't that the whole point? There's a breakpoint, and a lot of guys we don't hang out with with sliderulers, circles and arrows on a chalkboard, and pocket protectors have worked it all out. They know where it is. We have to FIND IT. They've already been there.
