Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2006 Envoy 2WD.

Body SUV

The 2006 GMC Envoy 2WD is cataloged as a two-wheel-drive SUV whose factory maintenance specification calls for a 6-quart fill of 5W-30 API-grade engine oil. That capacity and viscosity rating establish the baseline lubrication requirement for the model's powertrain configuration. Researchers referencing this model year should treat the stated oil volume and grade as the definitive service parameters for any technical analysis.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Every 50,000 mi	Engine Air Filter Element (replace) · Transfer Case Assembly (drain & refill)
