What is everyone using in their skyactiv 2.5L motors? I generally use Motul in all my vehicles but wanted to hear what others had to say. I do drive my vehicles harder than most which includes autocross events in the summer. My 2017 Mazda 3 should arrive this week so Im digging into the nitty gritty to ensure the longevity of the motor. I will not be going to the dealership for my oil changes, I use a local performance shop that I trust way more than any dealership. All paperwork will be saved/filed accordingly to ensure my warranty remains intact.
