I have an 02 tahoe with around 180k on it. It sits as a spare 99% of the time, probably a thousand miles a year, if that. So far I've put conventional oil in every 3k. It's a great vehicle I want to keep going as long as possible, (plenty of spares available, not too many electrics, tough & versatile).
So who would use high mileage oil or synthetic instead of good old dino ?
