    The temp gauge shows normal operating temp. Would low compression make the car sluggish? It has plenty of pep.

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

    Low compression would decrease the power. If you say it has plenty of pep that's probable OK

    If it is a V8, that is a factor. How many miles does it have on it.?

    From personal experience, I noticed an improvement in my F150 (with 125,000) when I replaced the spark plugs, the spark plug wires and the distributor cap.

    Sorry I can't be more helpful

    Plugs probably won't affect gas mileage that much but it sure makes it run better

Fuel gauge not working on my 2002 Pont. Grand Am SE light came on and won't go off so I don't know how much gas is in my car


Normally when the gas indicator light comes on, you have about 2 gallons left. Fill up your gas tank and reset your trip counter. Next time your gas indicator light comes on, check how many miles are on your trip counter. Use that number as a guide to when you should fill up with gas. Remember to always reset the counter every time you fill up. Good luck!

What is the normal fuel comsumption for a nissan navara


when you say it seems to be using too much, that is just a feeling
what you have to do is fill it right up and press the trip meter on the speedo
then you drive/use the vehicle normally until you are around 1/4 tank on the gauge
fill it right up again and record the reading on the trip meter
reset the trip meter and use normally again
repeat the process say for 4 tank fills recording each trip distance
then you will see what the fuel consumption is for example 40 liters for 400 klms is 10 liters per 100 klms or 20 galls for 200 miles is 10 gallons per 100 miles
the requirement to record distance and fuel put in will give you an accurate consumption over traffic, driving and atmospheric conditions from there you can ask --is this consumption figure around right for the car?

Control in dashboard somtime show fuel and milage and sometime not


Sounds like the electrical cluster went out. Not a cheap fix either. I was told that it would cost over 600 just for the part. I use my trip meter instead. once it gets to 300 miles i fill it back up.

I put in a new battery. I went to get it inspected and it failed. The inspector said I needed to drive it about a hundred miles before the computer will reset. Then bring it back and have it inspected...


Once disconnected from the battery the computer needs to go through a drive cycle during which it does internal testing of the sensors. Generally that only takes a trip of about twenty or so miles. The inspector probably told you one hundred just to be on the safe side. Most times, you don't need to make the trip all at once but over the period of about a week, driving normally, with a few longer trips mixed in, everything should re-set.

I bought a used 2003 A4 Convertible Audi 3.0 Feels it burns more gas than expected. Is there anything I can check or do to reduce that. Thanks Sean


to see what you get for mileage, take it to a gas station and fill it till the pump stops and reset your trip meter. Drive it around like you normally would to work or whatever till the tank is almost empty and go fill it up again till the pump stops. Its best to go to the same pump you used before. Once it is full look to see how many gallons or liters you put in(This is how many you used since the last time you filled up). Take the number of miles/kilometers from your trip meter(the number of miles/kilometers you drove since you last filled up) and divide it by the gallons/liters you used and you will get your miles/kilometers per gallon/liter. Compare this with the rating your vehicle is suppose to get. But remember it can very depending on how you drive.
Miles/kilometers divided by gallons/liters

How many miles per gallon does my pontiac get?


Fill the gas tank till the filler nozzle clicks

Zero the trip meter

Drive the car for say 100 miles

Fill up the tank again until the nozzle goes click again

Take a note of the number of gallons you put in divide that number into 100

So 5 gallons divided into 100 will tell you that the car is doing 20 mpg

if you have added 4 Gallons and 3 pints then divide the 100 by 4.40 which gives you 22.73mpg

Gas light stays on even when tank is full


the float sensor attahced to your fuel pump sounds as though it is not working properly. Usually this occurs when the car rides on E many times and becomes damaged. depending on the model it may be necessary to replaced the sensor assembly or if it is the complete unit the whole fuel pump.

Also, depending on your driving habits your car can use more gas if your are driving in traffic (stop and go). Average out your fuel mileage by filling up a few times and keeping a log of the gas consumed. Do this by reseting the trip meter when you fill up and when you fill up again divide the total mileage on your trip meter by the amount of gas you used by getting the amount of gallons it took to fill up again. ex. 360miles divided by 10gals = 36 miles per gallon.

note. make sure you check your air filter (is it clean?) and tire pressure (32psi) these can be contributing factors to poor gas mileage
