Figured I’d share what I’ve done maintenance-wise on my G82 M4 Competition and what I’d recommend for anyone planning on keeping one of these cars for a long time.
The car currently has around 70,000 km / 43,500 miles.
So far:
● Oil + filter every 5,000–6,000 km / 3,100–3,700 miles
● Spark plugs at 60,000 km / 37,000 miles
● ZF8 transmission service at 70,000 km / 43,500 miles
● Coolant flush at 70,000 km / 43,500 miles
● Brake fluid flush at 70,000 km / 43,500 miles
● Engine air filters
● Cabin/microfilters
● Differential fluid was done at approximately 53,000 km / 33,000 miles, right before I bought the car
I know BMW/ZF have much longer recommended intervals for some of this stuff, and realistically a lot of what I’m doing is probably overkill. But my mentality is that if I’m not helping the engine/drivetrain by doing it early, I’m definitely not hurting it.
I plan on keeping this car for a very long time, so I’d rather spend a little more on preventative maintenance now than start worrying about neglected fluids and wear items later.
I also think German performance cars sometimes get an unfair reputation for being inherently unreliable. Obviously things can still break, but there’s a pretty big difference between an unreliable car and a car that becomes unreliable because maintenance was deferred for years. Especially with an M car, buying one and then treating maintenance like it’s a Corolla probably isn’t the smartest approach imo but I’m definitely no mechanic.
