I do an oil change once a year since i only average 6000 miles a yr but if i follow efthreeoh's plan than I would only had 3 oil changes in the 8 years I had my car lol.
So i guess what im trying to say is you need to look at how long you havent change the oil rather than by mileage
That's about right, two oil changes a year. Just changed it on Wednesday before I went to work. It was a bit early because I just went down a full quart on Tuesday night with about 900 miles left before the CBS was calling for an oil change. I figured why waste a good quart of BMW 5w-30 for only 900 miles. The OCI this time was 16,885; figured I give the engine a break. LOL

Oil change #13 at 212,500 miles. So, 12 oil changes for 212,500 miles equals 17,708 average OCI.

You are following BMW's maintenance plan too since they call for an oil change regardless of mileage every 12 months as a minimum.

To replace the fuel filter, the part is around $150 and requires pulling the rear seat cushion, accessing the fuel tank panel and pulling the fuel pump out of the tank (dripping of fuel) and getting it out of the interior without dripping gas all over the place and having your interior smell like fuel for a week. Second, why would you replace a radiator and/or coolant tank when it's not leaking? Most modern cars need an air filter replacement at 50,000 miles; BMW's interval is every 3rd oil change, or about every 45,000 miles. Your CBS should tell you when to replace the cabin airfilter (micro airfilter). Keep in mind most cars until recently didn't even have one; it's just a stupid filter the car companies have added in as a high-profit service item.

So my 211,000 mile E90 325i (N52) has had the following regular maintenance:

Engine Oil: 12 changes @ an average 17,500 miles
Diff Oil: 2 changes 1st @ 76,880, 2nd @ 159,000
Trans oil: 2 changes, 1st @ 90,000, 2nd @ 159,000
Coolant: 3 changes, 1st @ 77,000, 2nd @ 134K (T-stat), 150K (water pump)
Brake Flush: 3 changes @ 2-year intervals
Power Steering oil: 1 change @ 151,000 (did it just for fun)
Engine Air Filter: 4 changes @ about every 50,000 miles
Spark Plugs: 2 changes 1st @ 99,000, 2nd @ 196,000

What you left out for an N52 is VANOS solenoid clean and swap, which I recommend every 50,000 miles.
This is helpful, some long term real world experience. Some may not completely agree with everything, but car sounds like it has had good "bmw" maintenance
