Since Bmw switched from Castrol to Shell, what motor oil are you guys using ??

[doni01]

Hi guys, just like the title says. Since Bmw now uses shell oil, are you guys making the switch as well or staying with the Castrol ?? My oil change is coming up and all I have ever used was the Bmw Castrol but now don't know if I should just go to walmart and get the Castrol there or switch to Shell. Thanks in advance...

Does the Wal Mart sourced product meets the BMW specs?

Obviously now, yes But they will decrease the change interval to 20 k miles so that will compensate

I personally will never put anything than Castrol in my cars. Except Motul in my race car, but this is another story.

The US based Castrol oils are garbage. They can sell a synthetic that is not really a synthetic. That same oil cannot be marketed as synthetic elsewhere in the civilized world. So I prefer to use a reputable brand oil.

You want an oil that supports the longlife 04 specification.

Catrol has a 0W-30 "European Formula" you can buy here. I've been told it's the same as the BMW stuff, but obviously slightly different viscosity. However, if a car calls for 5W-30, 0W-30 is not going to do you any harm, in fact it'll probably be better for the life of your engine.

That is not a US based oil though.

There was a problem with this before and now Castrol bottles are marked "Full Synthetic" and "Synthetic blend".
From what i know the black bottles castrol is a full synthetic and that is what the bottle says.
I didnt send any oils for analysis, but judging by the visual condition of the oil I drain after 7-8 k miles it cannot be anything than a premium oil.

I have always used Mobil 1 and so far so good, I have a 35D.

It still is a problem. The US based synthetic oils that Castrol sells cannot be sold as synthetic anywhere else. It comes down to what Castrol views as a synthetic oil, not how it is marked on the bottle. Their view of what a synthetic oil is different in the US compared to the oils they produce in Europe.

You probably have better knowledge on this. Looks like the one recommended for the diesel is a real synthetic, probably that is why they call it "Proffesional"
