I'm right with you on your quest
I'm not specifically trying to be the best, but I'd like to get 50+ average for my commute. I've hit 54mpg over 427 miles on a all highway trip so I got a bit of work to get 50+ on a 50/50 city/highway commute. Anyhow, after looking at your gas log, you've made tremendous progress and haven't pleateued yet, I've hit a pleatue around 43/44 mpg. I've found that I need to mod around my commute, as well as drive better. I'm easily hitting 50-60mpg on the highway portion, but the city traffic and stop lights are killing me, not being able to EOC really hurts us compared to the mtx fellas. Focus on mods that will make your regular commute more effcient.
For myself, I think 50+ is completely reasonable to hit next year, God willing
I think you should expect the same!
