Re: oil consumption in M5

[DEVIOUSM3@xxxxxxx]

As to my knowledge of this car and speaking to several owners it is common 
practice for the car to brun a little more oil consumption than you have 
stated

my M5 a 2000 model has been using oil at a very high rate( 1 ltr every 7-800 
miles) since i got the car new....it's had all specified svcs at the dealer 
and i now have 66,000 miles and can't figure out why? 
any answers here?


First off the normal oil conusmption for this car is 1-1.5 quarts per every 
1000- 2000 miles or in between scheduled oil changes they consume more 
depending on the type of driving you do. One close friend drives his M5 hard 
every day but religiously checks the oil ( as he was told by the dealer to do 
so) and has spare oil containers from BMW  6W40 or 50 I believe is the oil 
used for that car. Every E39 M5 owner has the same registered complaint about 
the M5 and in response by one BMW dealership was 

HOW DO YOU EXPECT A HIGH REVVING V8 (that allows you to rev up to almost 7500 
rpm and give you a nice substantial power band throughout the rpm range )TO 
NOT CONSUME ANY OIL? 

Well my experience with high revving motors is that the higher the engine can 
rev and produce horsepower at high rpm's it is a tradeb off between oil 
consumption and longevity. The BMP touring car had a 2.0L 6 cylinder that 
produced around 200-250 horsepower but it could produce it almost any rpm and 
it had redline of 11,000-13,000 rpm. It would consume oil and it was a motor 
that lasted a couple of hours " NOT MILES".

Consult the local dealership and ask some trained M mechanics what they think 
about the oil consumption. I belive it is normal for that motor.
