im 19 years old live on my own work and go to school have my own apartment and live in LOS ANGELES so gas price are higher here then any where as far as i know and i use premium using anything else is just going to hurt you in the long term i get 20 mpg and i drive 80 to 85 on the freeway twice a week for 60 miles both ways if i drive 65 ive been able to get 25 mpg its way better then when i had my lifted crew cab silverado and was getting 8 to 12 mpg so buying premium should be an issue just do it its recommended for a reason chrysler/ mercedes did the research hence why they put premium on the gas door to remind you
