BMW E92 M3 Maintenance
The S65! Some see it as a blessing, some see it as a curse, the “death” of the proper M3 engine. Its funny how now the M3 is turbocharged people miss this motor more…Well, hate it or love it, this is one MEAN v8. Due to this E92 M3 Maintenance Schedule is a crucial component to a long happy life.
8250 RPM redline, 4 liters, 12:1 compression, 400+hp, 300 ft lbs of torque, it’s really quite a piece of engineering. One of the kickers for us is the “condition based service” intervals. This is great, because for the first time in a long time does a manufacturer actually tell you that the mileage an time are not good measures for M3 Maintenance intervals…. Which is the truth! 5,000 miles on a high way commute back and forth to work versus five thousand miles around Lime Rock, are two totally different sets of demands, just like two years of being ran every day versus two years of running once a weekend, are two totally different amounts of wear and tear for the E92 M3.
There are a few things to do though to keep your E92 M3 running in tip top shape! The first is our basic Oil Service Kit, OEM BMW Filter and Liqui Moly 10w60 GT1 oil. This is recommended to do every 5k miles or 6 months of regular street driving use.
It’s very important to keep the inside of this motor well lubricated and being that it takes 10 liters. If you’re a gorilla with the tools we keep the drain plugs in stock too, but definitely not something you have to change EVERY oil change, every 3-4 should keep you safe. Doing frequent oil and filter changes with high quality oil will ensure proper lubrication and tolerances between components especially due to the fact that the M3’s S65 V8 is already prone to execrated rod bearing wear.
The next maintenance kit is the slightly more involved service procedure which also takes care of air filtration. This kit is comprised of Air Intake Filter, Cabin Air Filters (4), and Spark Plugs (8). BMW recommends doing the Filters once a year, the spark plugs once every 40k.
Secondly is the Air Intake Filter which I have to say looks like one of the most performance oriented OEM filter solutions I have ever seen.
Then we have the sparkplugs. They are as high quality as OEM but like anything in a highly stressed performance engine, something to change out more frequent than recommended to keep the car running in PEAK operation.
At this interval BMW also suggests servicing the transmission and differential. Since the required components differ between the DCT and 6 Speed the parts aren’t listed here but they can be purchased separately on an order by order basis.
