This is a new Mazda 3 Hatchback purchased August, 2018. Factory oil was drained at 2900 miles and filled with Milesyn SXR (full synthetic) 0w20 including 1/4oz of ZDDP and 3 oz of LubriMoly #2009. Oil filter was a Fram XG 6607. This oil report shows 5100 miles of use on the oil accumulated between December 2018 and April 2019 (winter season). A magnetic drain plug is in use.
This vehicle has very adequate engine performance and gets great fuel economy. Since ownership, fuel economy grand average is 34.2 MPG. I was concerned about fuel dilution in this GDI engine. Daily commute is 15 miles (one way) taking 25-30 minutes. I have my doubts the engine fully warms up in the winter.
The replacement oil/filter was the same as above. I'm going to tweak the moly upward about 60 points. Next time around, I'll tweak the Z/P downward about 100 points.
I'm wondering why the insolubles are at 0.04... Not going to lose sleep over it or the high copper (for now).
I've been using the Milesyn for many years and I'm going to stick with it and my "recipe" for a while. My commute and typical routine has me driving this vehicle about 12,000 miles/year and I'm planning (for now) to do OCs in spring and late fall.
Enjoy...
