He changes his spark plugs and his serpentine belt every 100,000 miles. He also runs synthetic oil and changes his oil and filter every 5,000 miles.

I can't find the post, but he had a guarantee on his Wal-Mart battery that by 2010 was no longer offered. He was getting his battery replaced every year for free by Wal-Mart (I imagine that he took the battery to Wal-Mart each year and the quarantee must have allowed free replacement if not meeting a certain benchmark). I don't think I've ever seen a battery warranty duration of longer than 5 years, so I imagine that warranty is no longer in place (assuming he replaced the OEM also at 1 year). IIRC, he does all of the repairs and
maintenance himself.
