Hey Scotty, I came across this question when I was watching your video regarding octane level for the gasoline. I now understand it's best to follow what the owners manual states. However, in this case is it okay to mix the gasoline? I wanted to ask this question, because my dad owns Honda pilot 2013 model and he's been fueling it with premium thinking it's better for the car. He had no problem and still runs like a clock. I will most likely get that car from him as my first car. As a broke college student I realized gas is quite expensive. So I wanted to make sure I can fuel with regular gas, which the owners manual states to fuel the car with 87 or above. Or do I have to continue using premium gas since it's been powered by it this whole time? 

Thank you and have a wonderful day!
