My H3, will be a year old in April. Up to this point I have been changing my oil every three months, regardless.
Now that the first year is almost done, I think the motor is pretty well broken in. I only have around 7600 miles on the truck. I will do one more three month oil change in April, have the air filter and wipers changed out as well.
Then...from April on forward,
The PCM will be the oil change indicator.
