How much money in gas will i spend in a 224 mile trip, at $2.29 a gallon?

SOURCE: High gas usage

I was just listening to Car Talk on NPR (Click & Clack) talking about this exact thing in response to a callers complaint about poor mileage. Their advise was to: a. check the compression and b. check the thermostat.
With your 2001 being 7 years old your mileage is probably under 100,000 so your compression is probably OK. If you do check it the good compression should be about 150 PSI; if it's down around 100 PSI that could account for the poor mileage.
As for the thermostat if your engine temperature doesn't get un into the normal range fairly soon, the computer thinks the engine is cold and adjusts the choke accordingly which uses more gas

Hope this helps Good Luck Loringh

You could fill the tires with Nitrogen but it will cost about $15 a tire. You will gain 1.5 - 2 miles more a gallon. Big trucks were made for pulling and hualing only. If your looking at gas mileage then you need a focus.

Please key check the crankshaft position sensor and the ignition coil, when the crankshaft position sensor failure will lead to the engine ignition time too early or too late, when the high voltage ignition coil fault is that the ignition is too weak, these two problems can lead to the lack of engine power and adverse symptoms such as waste oil, and in the two components without completely damaged, computer fault, it will be very hard to check especially the crankshaft position sensor.auto diagnostic tool.
