This 2007 Mazda6 2.3L is my wife's daily driver that now sees very little annual mileage. We're the original owners and I drove it for a couple years before my wife commandeered it. FYI: She's one step short of full-blown speed demon. The vehicle has a 5sp manual and she tends to hold the gears for a long time. This is Milesyn 5w/20 syn-blend and is about 9 months old and has NO 3rd party additives. This is the first UOA ever done on this vehicle. It has never had a mechanical problem or repairs of any sort.
Comments about the CU, SI and NA are welcome. I personally tend to think the NA builds-up over the winter as there's a lot of road salt in the winter. This oil went in before last winter. There are no issues with low anti-freeze levels.
Your thoughts?
Thanks
