I check my oil every few days, usually have to fill it up a bit. Car burns a bit of oil, I suspect the turbo needs to be replaced. I check the tires whenever the thought occurs to me, usually once every month or two. I probably need to do that more frequently but it never seems to be low when I check it. I change my tranny fluid every couple of oil changes and usually change my oil and filter every 1500 to 2000 miles. I do a lot of short trips and I don't have an oil cooler; my oil tends to break down quickly even when I use Mobil 1. I haven't changed my transfer case or rear diff lube since right after I got the car- I'm probably going to change those out sometime in the next few months, though they should be good for 30000 plus miles and I've only put less than 10 on them. My clutch gets bled whenever I have the tranny off, which is usually every few thousand miles. I've bled my brakes a couple times in the recent past because I keep burning up the cheap discount auto fluid with stops from 120+ down to 40 or 50, when I replace my crappy warped stock brakes I'll use some motul or something and bleed every six months. My coolant is just water with water wetter, and I usually flush it out every few months to replace it with more water/water wetter. I check the overflow level every time I check my oil.
