Do new cars get worse gas mileage at first?
A. My experience with many new cars is that they don’t return the projected fuel economy until the engines reach 5,000 to 7,000 miles, some engines even more. The gasoline that we use during cooler weather and short trips can have a dramatic impact on your car’s mileage.
Do brand new cars use more fuel at first?
Generally for the first 500-1000 miles new engines are tight and will use a bit more fuel. You will see that the maker tels you not to exceed certain revs until the engine has bedded in. Years ago older engines had to be carefully run in up to max speeds for mileage covered.
Does your car get better gas mileage with a full tank?
Gas Mileage A lighter load does require less gasoline, but the weight of a full fuel tank is not significant. Your car may actually be less efficient when the tank is near-empty, as more air in the tank can increase fuel evaporation.
Do brand new cars need to be broken in?
In short, yes, they do. Most automakers advise a brief mechanical run-in, or break-in period, at least for the first few weeks someone takes home a new vehicle. Each vehicle will have different requirements, owners are encouraged to take a closer look at their vehicle’s owner’s manual for specific information.
Do modern engines need running in?
A: Most new cars don’t require running-in, but you certainly won’t do your engine any harm by taking it easy for the first few hundred miles. This used to be the responsibility of the owner, but many modern car engines either don’t require running in, or the procedure is done on a ‘bench’ at the factory.

How can I tell if my gas mileage is too low?
Periodically checking your tires with an inexpensive pressure gauge is a good way to catch this. Just be sure to use your car manufacturer’s recommended pressure levels stamped onto the driver’s side doorplate and not the “maximum pressure” numbers shown on the tire itself.
