If an engine uses oil, can you change it less often?

Good topic. +rep

I would also agree with you and since you’re adding a new quart of oil (which is probably 1/4 of your entire engine’s oil) that it would add back to the viscosity/detergents/etc that was lost. Not to mention it has disposed of a quart of oil that had contaminates (dirt, fuel, etc) already suspended in it.

Are you burning, leaking it or both?

Just burning. I (and I’m sure Toyota) consider the usage completely normal for an engine with over 250K on it.
