What oil did you use in the last uoa?
And what gave you the confidence to run to 14k miles this time and 12k miles since your last UOA of 7k miles?
Slow your roll Apollo.
The previous run of 7k+ 4 years ago was generic green bottle Quaker State 5w-20 from Menards. While oil color is not a significant factor, I believed I wasn't stressing oils enough based on just how clean they were coming out. That may not give everyone "confidence" to go 10k+, but I am not everyone.
14k miles honestly snuck up on me, as we traveled most heavily in our SUV vs my commuter Accord. But as I mentioned, I am down to once a year changes, and always in Fall. I wasn't watching mileage, as typically its 12k per year tops.
