2004-2006 Pontiac GTO Maintenance Schedule

Following a maintenance schedule for your vehicle will not only improve performance but also improve longevity in how long your car will last. Avoid costly repairs by regularly maintaining your vehicle and inspecting and servicing it at the required intervals. A maintenance schedule includes inspection as well as servicing your vehicle to ensure it is operating as safely and efficiently as it should while driving.

The Maintenance Schedule can be found in your vehicle’s owner’s manual and also in the service manual. For your convenience, I have made the following maintenance schedule for you. The maintenance for all 2004-2006 Pontiac GTO’s is the same. The 2004 Pontiac GTO has the LS1 5.7 Litre, and the 2005-2006 Pontiac GTO’s have the LS2 6.0 Litre engine. Both engines require the same maintenance and service.
