Here's my fuel savings after switching from a CX5 to Prius
I had been driving my 2016 Mazda CX-5 to work daily, and had to re-fuel once every week. Then I decided to get a used 2010 Prius and now I put gas once almost every 2 weeks! .Work is about 30 minutes/ 22 miles each way, with about 90% spent on the highway.
At this point, I'm sold on Prius's fuel efficiency!
PS: I used this online Fuel Savings Calculator ,that I recently build, to help me do the fuel costs/savings comparison.
