What problem are you trying to address, dspace9?
Thanks, I'm trying to keep up with the recommended schedule of regular maintenance for my 2014 Mirage best I can and sits at around 70,000 miles right now, or 110,000kms here in Canada, and I have had the car like 70 months now.
Not addressing any specific issue, my Mirage is in the shop all weekend til Wednesday atm, just wouldn't mind maximizing fuel efficiency and engine's best possible performance.
