Hi Eric!
Britt Releford (rel e ford) here.
2011 Mazda Speed 3, 2.3 Turbo-charged engine all stock, 70k miles. Changed the plugs at 55k as per Mazda recommendation and they were fine. The car does not use oil at all. It runs great but I have noticed that the tailpipes are always sooty and occasionally, see a puff of black smoke when I accelerate. No codes in the ECU and the gas mileage is better than the average for this car. Any thoughts as to the cause?
Thanks for all you do and keep the Fairmont vids coming.
