I'm running Mobile 1 synth with Wix filter. Since the majority of my driving is less than 10 minutes (to/from work), I'm changing my oil and filter every 3 months. I have not gone over 2000 miles between oil changes.
So this summer I've been riding my bike a lot. The WRX is due to have the oil changed this month. Looking at the trip meter, I've only gone a bit over 600 miles since the last oil change.
Do you think I should still change the oil? Or do you think I can wait till my next "scheduled" oil change in December?
