Hi guys and gals, here's the very first UOA from my Brand Sparkling New 2014 Mazda 3 Hatchback.
The factory fill ( Mazda's 0w20 ) was dumped after 1,000 miles of hard city driving and Mobil 1 0w30 AFE was poured in and sampled after 3,000 miles on the oil ( 4,000 miles on the engine ).
I decided to check on the condition of the oil after only 3,000 miles in order to see if my relatively short city sprints are causing fuel dilution with this DI engine. Although I'm glad to see that no serious amount of fuel is present, I'm also wondering what lowered the viscosity...?
When I choose to run the 0w30 instead of the factory recommended 0w20, I did so because of my location ( sunny Florida ) and the fact that the engine is already beginning to be modified ( aftermarket intake and exhaust were installed @ 2,000 miles ) so the car is driven in a VERY spirited manner 90% of the time, as I constantly push the 2.0L engine to deliver the advertised 155hp / 150tq at Redline to get me from point A to B in a hurry.
I don't see any effect on gas mileage with the thicker oil, and even with the abusive driving, I'm averaging 27-33mpg with 70/30 city / highway sprints around town.
Anyway, this oil was drained when the sample was taken as it's part of my early flush procedure ( change FF @ 1,000 miles and then another oil change after 3,000 miles ) in order to flush out the break-in shavings. I plan to run the current fill of M1 for 5,000 miles and resample and go from there based on the results, although I'll most likely stick with 5k OCIs while the engine is fresh.
