I used to live and die by Mobil 1 0w-40 on my amg. Now i use LiquiMoly 5w-30 and 0w-30 on both X5 and M5 (in between dealer changes).

Buy it from FCPEuro and then just return the old oil.

Haha yes. That is where I buy all My stuff. I would be curious what it costs to ship back all that liquid. Just for a reference. Lol

Can't speak for him, but personally after watching the 0-30 gush out of my oil pan like water I wouldn't trust it to actually lube anything lol.

I don't mean to be a dick, but that's totally contrary to what we know about modern multi-vis oils. That's what you WANT. A huge amount of wear happens at startup, and too thick of an oil will take FOREVER to get to the valvetrain and bearings under pressure (seconds, but at 1000 rpm, one second is a long time).

Just sayin'

Well yeah, but the 1 second at startup happens a lot less than 7k rpm where the oil turns to froth because it's so thin haha. Plus the difference between 0w and 5w at startup I doubt is going to change much of anything. Both the f10 and f90s were rated for 5w40 with some other weights being acceptable per the owners manual, they changed that in 2020i want to say when they needed to meet stricter emissions standards. If you don't drive your car hard or don't track it I'm sure 0-30 is just fine, but I've seen it turn to bubbles on other people's cars.
But this is the great oil debate and there is no right or wrong answer and honestly it's just subjective and whatever people want to do, at the end of the day oil is oil and as long as you're not doing something ridiculous like 20-60 or 0-16 I'd say you're gonna be fine 🤣🤣🤣

[Danny D]

so use 0W-40, simple.
I'm switching over to that next week.
IMO 30 is too thin in our 40 degree celsius summers

Edit:
so for me I run 0W-30 winter
0W-40 summer.
4 years now.

2nd edit.
Did the same on my previous BMW - that I had for 12 years before selling, no issues, car ran like a champ.

For the most part, you're right. But, it's pretty straightforward, a 10W-30 is the most stable oil over time. The 0W-30 gives it better winter flow characteristics but sacrifices some stability. Adding the 40 makes it thicker for high stress use, but the bearings and clearance have to be built for it. Of course, there's a break point somewhere. If thicker=better, why not a 0W-100? Who knows where it is? The engineers who made the car have the most testing under their belts.

I just wanted to know why that oil and that weight. Wanted to catch the reasoning.

Yeah, I do 5 40 since I drive the car every day so it doesn't sit for too long, as well as the fact it's like 90-100 every time I start it up🤣🤣. But I go 40 because I literally beat the shit out of my cars, so I feel better about doing it knowing my oil isn't frothy haha. I'd argue that generally thicker is better but yeah there's always a limit haha and depends on climate and other things, I wouldn't run 5w40 in Siberia during the winter for example lol id argue even 0w30 is a bit thick under those circumstances🤣🤣.

300V 0W40

Using BMW 0W-30 what the M5 came with from the factory. I paid $10.26 a bottle and $20.93 for the oil filter. Just completed the oil change today. Piece of cake.

[pbonsalb]

I like the fire extinguisher in the background for safety. Did you spill any oil when you changed the filter?

No, I loosened the oil filter housing and let the oil run over the housing into the oil pan below before separating the oil filter housing from the engine.

[pbonsalb]

Interesting. I still had dripping onto the metal belly pan. The new filter cap with drain plug looks like a great part to change.

How often you change the 300v?

Is the oil filter cap with drain plug part #11-42-5-A34-A34?
My X5M came with the oil filter cap that doesn't have the drain plug.
They are both the same price.

[pbonsalb]

Not sure of PN but someone posted it recently. I think it is a part that may or may not have a suffix or may use the original part number. I have an aftermarket version that was available before the new factory part. I thought the stock cap even with slow draining was still too messy and that a drain made sense.

11425A33C43 is the oil filter kit with new drain plug.

And yes 11425A34A34 is the cap with drain plug.
