GTX: Every 4 months or 4,000 miles
GTX Synthetic Blend or GTX High Mileage: Every 5 months or 5,000 miles
Syntec or EDGE: Every 6 months or 6,000 miles
8/150k warranty with GTX
10/250k warranty with GTX Synthetic Blend and GTX High Mileage
15/350k warranty with Syntec
15/500k warranty with Edge
Of course, vehicle must be less than six years old with under 100,000 miles. Warranty is not transferable and you are only allowed one exception.
Not a bad warranty I must say, as it doesn't require the same interval for every oil type.
