I find that doing your own maintenance is very rewarding. I bring my kids out to change the oil and show them the parts that are being replaced. The kids are 9, 7 and 5. The two younger ones really enjoy the hands on. I also work on cars with my brothers and friends, just like the good old days in high school, have a couple of pops if yoy know what I mean.
