I hate not having a dipstick!! I don't care if the car tells me the oil level is fine, I like to SEE the oil on the stick. BMW's recommended oil change intervals (at least on regular 3 series) is nuts (15,000 miles!?!) I'm running 5,000 mile intervals with samples going to Blackstone.
I think I'd be one of those that actually USES a dipstick. Nice to know I'm in the top 2% to 3% of BMW owners!
