Oil changes today on the cars. I try to do both cars at the same time, so I only have to clean up once. I do them very three months, regardless of mileage, which is always below the factory specs anyway.
One thing that's a pain -- they use different grades. It was easier when the wife and I both drove Chrysler minivans, which used the same grade of oil -- 5w-30. But the '95 Olds my in-laws gave us last fall uses 10w-30. Oh well.
Another thing -- oil-pan capacity. The Olds takes five quarts, which is a little odd. But the Town & Country takes 4.5 -- what's up with that?
Speaking of oil, doesn't look like we're gonna get a break on prices anytime soon.
