i was reading the handbook for the z4m last night,the book says use 10-60 oil but the ltr of oil in the boot is 0-30?which brand of oil and which viscosity do you people out there use in your z4m cars?also what brand do bmw put into the car come servicing time?i really dont want to put two types of oil in if the car needs a top up every now and then.
 
I just use the standard 'Castrol Edge 10w60 for BMW M engines'.

The 0w30 in the boot must have been put there by a previous owner in error or may simply be a 0w30 container to hold 1 litre of 10w60 oil from a larger container?
 
Get in touch with your dealer ASAP to find out what was put in to the vehicle on last service. If they put in 0W30 instead of 10W60, then that dealership NEEDS to change it immediately and on their dime. M cars MUST use 10W60 per manual and using anything lower as standard can and probably will void the warranty.

The manual states you can use some others for topping up if there's no 'Castol Edge 10w60 for M engines' available.

Alternative oil grades
If a high-performance synthetic oil approved by BMW should be unavailable, you may use small volumes of other oils for topping up between oil changes. The following data must appear on the packaging:

Viscosity
preferred: SAE 10W-60
alternative: SAE 5W-40 or SAE 10W-40

Specification
preferred: API SJ/CF
alternative: API SJ, also SK, SL, S...

However if you suspect a full oil change has been done with the wrong oil, then you'd need to prove what oil is in the car at the moment.

but 0w30 isnt on that list...

No, it isn't. But we don't know for sure what oil is in the engine anyway. My dealer (that I don't use anymore) used to state 'Castrol GTX' on all their invoices even though they claimed they used the correct oil at service time :?

When was the oil last changed? Who did the oil change? Who put the top-up bottle in the boot?
If the car's only got about 10,000 miles on it then I'd assume it was done at a dealer, so should be easy enough to check, although they don't tend to give you a top-up bottle afterwards.

My top-up bottle was an old 1L Silkolene Pro-S 10w50 oil bottle, but it's got 'Castrol Edge 10w60 for M Engines' from a 4L bottle in it. My new bottle is a nice stainless steel one that I was given as a present (I think it's really a drinks bottle) :thumbsup:

If it's been topped up with the wrong oil and run for a few hundred miles, then there's no way BMW would ever know it's had a top-up of the wrong oil - even with an oil analysis. The only thing that would 'tip them off' would be the top-up bottle, so simply replace that.

Wonder what the difference is between the M series only 10w60 and the standard 10w60?

The ///M one has slightly less residue/ash when burnt, and thus should keep the engine internals cleaner for longer - that's why it's a long-life oil.

The actual specs are available on the OpieOils website...

the car had an oil change by bmw late last year so i am thinking its the right oil in the car.i will give them a call to see whats going on.i really cant see a dealer putting the wrong oil in and if things were to go wrong i should have a claim against that dealer i would have thought.i did ask about the oil in the boot when i was buying the car(private sale) and he said it was there when he bought the car 6 months ago.the car has only done 14500 and its an o7.
i will post some pics of the car soon. :D
 
13,500 miles including M service and oil service at 10,000 miles and so far it's not needed one drop of top up oil! Makes a change from my old 911 that used a litre every 2000 miles.

I carry a litre that i bought from BMW and even running to Monaco and round the Ring, it's never needed it.

I love these cars.
 
Same here. Never topped up the oil, but I guess that is because I bought the expensive 1 Litre bottle to put in the boot :D
