Question

Does a new car have a break in period before you get your best gas milege.

Answer 1

Yes.  Take it out on the highway to blow the carbon out of the filters and get the oil flowing.  

Answer 2

Normally drive at max of 60 MPH for the first scheduled factory oil change. That the oil they use is a break in oil, and the parts inside the engine are not totally clean from metal particles, during the stage of being built, and also dirt and foreign matter.

Answer 3

on a new car its usually in the first 5 thousand miles that it gets broken in real good,but you wont notice much difference if any in the gas mileage on it,most cars now will get about the same new or with 50 thousand on them,if you keep them tuned well,good luck.

Answer 4

At about 5,000 miles all parts are seated and fuel mileage is at it's best.
