OK, I admit that I don;t change my car's oil every 3,000 miles (gee, that would be like every other month, and it's synthetic, so it's $60). Anyway, I got a new van (Honday) and it says to change the oil every 7,500 miles. That seems too long. I'm almost at 6,000 miles and DH is nagging to get it changed. So, my question is two part--does 7,500 seem too long? And two, how often do you get your oil changed?
