Hi there guys, sorry for not keep updated,
I run 90% on city and rural roads, and i can run it on high ways also,
My top speed is around 125km/h, but my best mileage i did with a very calm down driving
This motor only takes 1L of oil, and Honda recommends change it every 3000km. Each maintenance on Honda costs near 27€ (36$).
Past 10 000km, the maintenace will be every 4000km i think
I think the next mileage will be a little better than 150mpg, lets see
