Hey all, This UOA is from my 2011 Mazda 6i 6MT with 40,465 miles. The oil was in service for 6,937 miles and just under 6 months. Mazda requires oil changes every 7500 miles / 6 months whichever comes first during warranty. I was previously using Mobil 1 0w20 (which is the first UOA sample at 9,885 vehicle miles). However it was too pricey for short intervals so switched to the Kendall. This UOA was performed on my 3rd fill with Kendall GT-1 Synthetic 0w20 so this should be a pretty accurate indicator of this oil and engine combination as previous oils have been drained out. I have been exclusively using Purolator Pure One filters since I purchased this vehicle. My air filter was changed at 21,249 miles on the clock and I believe it was a FRAM I put in. The miles for this OCI are 75% highway, 25% mixed suburban/urban. The present fill is again Kendall 0w20 with a Purolator Pure One. This latest OCI finished the 2 cases of Kendall I had in storage. Before purchasing more I wanted to see how this oil does in my application. After my warranty I plan on following a 10k mile OCI. Thanks for looking.
