Q#1
Im wondering what oil and oil filter you guys use if you do your oil change in your M3's ?
-stock bmw dealer oil and oil filter only
-another brand of synthetic oil like
~redline
~royal purple
~amsoil
or something like the new GREDDY oils now offered here in the states...
"GR Synthetic Oil is made from the finest automotive grade, Group IV, PAO and Ester base oils and specially designed additive packages, the GR oil is designed specifically to protect and enhance modern, small displacement, high horsepower engines. GR-3, the 5W-30 is ideal for high revving normally-aspirated engines, like VTEC Hondas. GR-2, 5W-40 works great for stock or bolt-on turbo kits, while the flagship GR-1, 10W60 is geared towards super high horsepower built-engines with high boost. GR synthetic oil can be purchased at any Authorized GReddy Dealer"
GR-1, 10W-60
GR-2, 5W-40
GR-3, 5W-30

i have read this thread http://forums.bimmerforums.com/forum/showthread.php?t=265292&page=3
but still left in the dark:help

Oil Changes every 7000-15000 miles (depending on your driving style):
7 quarts of 10W-60 at $8 to $11/quart + filter
*free if you car still has scheduled maintanence.

Inspection I/II every 15000 to 30000 miles (depending on your driving style):
$1200-$1600

1. Only one company makes the oil required for the M3 ... Castrol and it's only available through BMW. BMW/Castrol 10W-60. Use the OE BMW filter... aftermarket filters normally can't take the heat (pun intended) and break down much ealier than the OE filter does.

Change the oil as the car asks for it... if you drive it hard, it'll ask for oil changes every 6-7k miles. If you drive like a grandma, it will postpone the oil changes up to 15k miles. You should change the oil at least once per year.

2. 7

3. The SMG tranny works just like a manual tranny... when you burn out the clutch, you'll need to replace it. When you do, you'll need to reset the adaptation for the clutch engagement point. SMG units have been known to fail requiring the purchase of a new hydraulic pump.

actually, the S54 motors only take 6 quarts(at least in E46 M variety), instead of 7 like the regular 3 series.

An extra quart comes in handy just in case during an oil change.

Depending on environment, people in Europe and Australia have been recommending 0W40 oil instead of 10W60 to help the VANOS work better. I have been using Motul 0W40 E-tech ester based oil and it absolutely helps the VANOS actuate more smoothly than when I was running 10W60, even with hot oil.

I'd wait before trying any new oils, especially from a company that hasn't sold oil before. If you're using your M3 for street use, make sure the oils meet ACEA A3 specs. We sell Motul 8100 series of oils (all PAO or Ester based) for street cars and 300V for track cars, since the 300V oils *may* contain certain additives that are harmful to catalytic converters over long periods of time if your engine consumes oil.
