Hey people...
Does your M5 burn oil? And how much? Is it normal ; and what is normal and expected for these cars?

2000 miles on mine thus far, and no measurable oil consumption.

I just added a quart on the 22nd.... But I don't drive the car much. I'm monitoring it now to see the consumption. Just wondering if this is normal?

Yes it's normal, I believe BMW has said up to 1qt/1,000 miles is normal. I do about a quart every 1,500 miles, though I seem to burn more on highway trips. I did switch to the newly recommended 5w30 Castrol as well though so I expect that some of the additional oil burning is from thinner oil.

Also has anyone used a oil stabilizer like Lucas??

I would recommend against using oil additives on an engine like this. It might be ok on your average 4 cylinder, but at the level this engine performs I would not want to add something like that into the mix.

1 liter per ~1000 miles. Does that mean we should never need to change the oil? I mean in 15k miles, you have essentially put 15 new bottles of oil in there keeping things fresh. Just kidding, don't flame.....

i burn about a liter per 1,000 miles regularly in the past 3 years of ownership.

and yes, get an oil change. it helps to start fresh and swap your filter at regular intervals...

My car use to consume about 2-3.5 quarts every 7k miles. I changed my oil intervals to 5k miles and now it only consumes about 1.5 quarts every 5k miles. Is it normal? yes so don't worry about that part. All M motors consume a lot of oil.

1qt per 1100mi for me.

I just bought the car from a non BMW dealer, I wonder if they used the right oil or just usual El cheapo oil.
I'm kinda interested in seeing if the car runs better after a change with the right oil.

mine burns based on how much i use the M button - the less i use it, the less oil gets burned, the more I use it, the more I keep putting oil in.

You should ask them. When I bought the M5 from an Audi dealership, they used Castrol 5w-40 oil, and I had them replaced with TWS 10W-60.

What ios the active ingredient in lubro moly? I'm wary of anything that could mess with the oil viscosity - given the rod bearing issues on both S85 and S65 engines.
