Someone gave me coupon for free oil change, so it was my first experience to try a quick lube place and I got the oil changed. But when I went to change it the next time, the drain plug was cross threaded. I needed a breaker bar to back it out.
Then I had to buy new drain plug. At least they are...
I also do this in the summer. You would be surprised how long the maintainer shows charging hours after driving it. It really helps extend life of the battery, heard a claim someone had the same battery 19 years.
