Poor gas mileage
Hey everyone,
I have always gotten poor gas mileage with my auto BRZ. They claim 28mpg combined, but I was consistently getting 21mpg (average). So... I was having rough idle with my 2013 BRZ and the dealer reflashed the ECM. Since then I have gotten a combined 25mpg! I had "reset" the ECM many times with the battery disconnect (that did nothing). The dealer reflash fixed my MPG issue. Thought people should know! |

Well it is not fully broken in yet and driving habit would affect the mpg.

Driving habits are huge.
In the span of three days I had three fillups, two in one day they went as follows: 26 mpg, 12 mpg, 29 mpg There was nothing wrong with my car and if you exclude the 12 mpg I was beating the EPA ratings, the first and last fillups were a mix of freeway and city driving (commute) and the middle tank was a full track day. http://www.fuelly.com/car/scion/fr-s...tcaster/177974 See fillups 45-46-47, not sure why they're numbered out of order... Without a good idea of the sample size it's hard to judge if there was something wrong with your car or if you decided to wake up a half hour earlier for work and have a lighter commute. |
