So I have a low mileage 6.7 that doesnt get driven much so the yearly usage is low. I drive it at least once a week and it gets up to operating temp and not short tripped. No long idles at all, maybe 1-2 mins depending on the temperature outside... possibly up to 5mins MAX. I like to change the oil once a year, but Ive had thoughts that I should do it maybe sooner or maybe should I continue the once a year practice? Im running an OEM filter and I run Rotella T6.
Thoughts?
