Hello. I do my own oil changes and fluid changes. Last time I did my oil change, I did it at 20 pr 30% oil life on the maintenance minder. After, I reset the MM to display 100%. However, my limited understanding of the MM tells me that only at 15% or less oil life, the MM wil give me the maintenance codes related to my car. Does that mean that I have to let the oil life drop to 15% every time to get the maintenance codes? If so, Is there anyway to know the maintenance code before at above 15% before resetting the oil life?

Thanks for clearing this up for me.

 

There is a way to get it to display the upcoming code beforehand; the details should be in the owner's manual. Off the top of my head, I think it involved holding the mpg-o-meter selecto button in for a few seconds while on the oil life remaining page with the oil life between 50% and 15%...but my memory may well be faulty on the details.

 

That might be it but its definitely not in the manual. Does anyone know?

Anyway, I just got down to 15% and I got an a 2 which I believe is oil + filter. Does anyone really just change the oil and not the filter? I figure a filter is only 5$, why not change it every time?

 

No way I'd change oil and skimp on the filter. But that's just me. What does your gut instinct say?
