Oil blends and formulations and engines have come a long way in the last 
20 years where it was "every 3000 miles." A lot depends on how you 
drive. Open highway driving is easier on you engine and your oil will 
last longer than stop and go driving in the city. Pulling a heavy load 
will require more frequent oil changes than not pulling a heavy load. 
What does you manual say about oil change intervals? The computer 
estimates the oil change interval based on how the vehicle is driven. I 
don't know if I would believe it 100%, but use it as a guide.
