I've been using 10W-30 - both conventional and synthetic - since 8k miles
when I bought the car in 1995. 1500 miles on a quart is fine with me and well within warranty limits for a new vehicle per GM's criteria. And this is a 91 with the seals on both intake and exhaust ... The burn rate has not changed in 40k miles.
