I change it once a year around april with Liqui Moly. That's usually under 1,000 miles on the oil. I think last year might have been about 500. but I start her up once a month in winter and let her idle for 20 min or so. it is kind of a waste of oil but still necessary to change it once a year.2005 Phoenix Yellow M3 Coupe 6spd

The e46 M3 has two significant failure modes, that can cause you a LARGE expense if you wait for them to fail instead of addressing them preemptively. I would very much suggest locking down the VANOS bolts/tabs and the subframe BEFORE you have failure-- see post 4. This thread will be broken down into 3 sections 1. When to do'03.5 M3 SMG Coupe - Jet Black / Black

Change oil around 5k miles or so. Drive the car about 5k miles a year. Mixed use for occasional daily driving and weekend drives.Last edited by Ceelooboob; 04-08-2020, 09:18 PM.

My M3 is track only (trailered). I probably average 1500-2000 track miles/year. I change it at the beginning of the season and probably do 2 changes during the season...about 500-700 miles. Now, on my wife’s M3 which only sees one track day a year, I change it once/year which is probably about 2500 miles.
