Personally I wouldn't go 3 years since the amount of moisture that can build up in the oil over that time is just too much; I'd go 1 year or 7500 miles whichever comes first. The oil life study done a while ago by some shop with an LS1 Camaro got to well over 15k miles before oil analysis said "change it" to the Mobil1 they tested but I'm still not that comfortable with that.

If you have the money for a BMW, Porsche, high end sports car, spend the $50 bucks or get your hands dirty and CHANGE THE OIL.

It's not a freaking Tercel !
