Not referring to routine maintenance intervals, but more of a maximum one-time interval.
Mobil 1 extended is guaranteed for 15K. This is about a trip of somewhere between 10K and 15K in about 2 - 2 1/2 months this summer. Looking to avoid oil change until the vehicle gets home. Don't want it done on the road at Jippy Lube.
I normally use dino oil and change at 5K. Using synthetic it seems reasonable to be able to go at least twice that with normal (not severe) conditions.
