Well, according to the owners manual. The break in period is from 600-1000 miles. I've been babying the car since I got it. I hit 900 miles yesterday. And figure id have a little fun and give it the PROPER break in.

Before, I didn't let it go above 3000rpm. Last night. I used the paddles from a complete stop till about 70mph... going through first, second, third, fourth. redlining it. wow this car is PEPPY!! :-)

I love the FIT even more now... Now that my car is broken into... I hope to get better gas mileage! just filled it up yesterday around 29mpg... I drive city/hwy.

 

haha... mine is at 2700 now.. i've been bit careful on gas too..
i used to get 29mpg city/hwy.. then starting my most recent fill up..
it is showing 35mpg- 37mpg... suddenly..
looking foward to see your future mods...

 

Im using 89 gas.... Manual says to use 87... I dunno... I'll stick with 89.. what are you using?

 

Granted I don't HAVE my fit yet, I have never noticed a difference when running a higher octane then recommended and most of the time you actually will loose power. The octane rating is the fuels resistance to detonation, and the fit and other cars are designed to run on a certain kind of fuel and they are tuned for those parameters. The fits engine has no need for a higher octane fuel and really while its only a few cents you are wasting that money.

Personally I wish they would do away with mid grade, it seems that any more a car has to run on 87 OR 93 you rarely see a car that actually needs 89. Even if the gas companies did do that and it would cut down on costs and storage for two fuels as apposed to three we all know that money would just be diverted into the CEO's coffers.

 

yeah you should notice your gas mileage start to slowly go up....i was getting about 28-29 during breakin. im at about 9,700 miles and every fill up is either 32-37mpg (depending how much high way driving).

run Chevron 87 only got drop in filter and exhaust and its nice and peepy

ENJOY!

 

I never never never never never use octane higher than 87..
