Est. annual cost
$600–$1,000
The T1-generation Silverado 1500 introduced the new 6.2L V8 and 2.7L turbocharged four-cylinder alongside the proven 5.3L V8. The Dynamic Fuel Management (DFM) cylinder deactivation system on the 5.3L has had mixed reliability — regular oil changes are especially critical.

Maintenance tips
- 01
5.3L owners: the AFM system's lifters are the known weak point. Consider an AFM disabler (DOD disabler) and regular use of ZDDP-enhanced oil additives.
- 02
Always use GM dexos1 Gen2 or better oil — other oils won't lubricate the AFM components properly.
- 03
If towing over 5,000 lbs regularly, use the 'severe' service interval for all fluids, not the normal schedule.
