About 17,000 miles. Super B train hopper bottom.

just make sure you apply fuel mileage into your oil change interval. oil wears out/contaminates/separates quicker, the harder you work an engine. the lower the fuel mileage, the more often you should change it for maximum longevity vs. cost of oil replacements. too far one way or the other costs you more than necessary over the long term.
