2011–2014 Chevy Silverado HD / GMC Sierra HD 6.0L V8 gas maintenance schedule
From the factory owner's manual. "Severe" is the schedule the manual gives for towing, plowing, heavy loads, lots of idling, dusty roads or extreme temperatures. Your truck's own manual and dash reminders come first.
From the 2013 Silverado owner manual (Sierra HD is the same truck); other years of this generation may differ slightly.
