What is the average fuel consumption of a 1996 Toyota Tamarax FX GL Wagon?


do you want to figure out how to figure yours out. a 20 year old car nothing is going to be average. to get it better lose some weight in the car. meaning don't carry 500 lbs of stuff you don't need. the less it weights the less the engine has to work which saves gas use. fill your tank normal till the pump shuts off and don't pull the handle to add more fuel. then write down the mileage. drive the car 200 miles. fill the tank again the same way. then figure out the miles you drove and how much gas you put in the tank. if you drove 200 miles and used 10 gallons you get 20 miles to the gallon. doing a tune up and checking your air in the tires can increase the mileage. good idea to check it first before doing the tune up to show it did some good. I did a tune up once and got almost 5 more miles to the gallon after

Have 2008 kia rondo misfire on cylinder 2 also throwing code for map sensor...car drives and runs not getting best gas mileage and idles/runs rough where should I start thanks for your time


Misfire is caused by spark plugs, coil packs (if you have them), possibly wiring issues.
Don't you have long, long warranty on that car?

I have got a 2005 Equinox and I'm getting horrible fuel mileage ! Like 7mpg in the city and 17 to 21 mpg on the highway , I've put new tires , battery , original equipment spark plugs and wires and still...


There are many things that could conspire to rob mileage. My first thought was possible transmission slippage. Although your city rating is horrible, the highway mileage is just a little off. 23-25 hwy is correct, 23 for lousy doped California gas, and 25 elsewhere. My guess is that you have slippage but above 45 mph, you are still getting advantage once the converter lock takes effect in overdrive. Just slippage until you reach that lock point.
Start with a full diagnostic of all stored codes in the ODB II computer, both for the engine and the transmission, then an evaluation of your transmission from a good shop.
Good luck, the Equinox is a darned good car,and worth the effort.

Gas tank size , gas gage does not work , how many miles to the gallon the grand caravan get?


The gas tank capacity is 20 US gallons, but the tank will really only hold about 19.5 gallons. As far as mileage goes that really depends on your driving habits and the load it carries, just you? more? I would think that your average miles to the gallon would be in the range of 14-16 town and highway.
Here is the EPA ratings, which never match the real world gas mileage.

Poor gas mileage on my jeep liberty


change your spark plugs if they haven't been changed in awhile. check your tires for the propper psi there should be a sticker on the inside of your drivers door that will tell you recomended air pressures go by this not the recomendations on the tires. also where are you getting you gas does it contain ethanol sometimes this can burn faster.

Jeep liberty gas mileage


to increase gas mileage make sure you keep on top of tire air pressure you can also have your tires filled with nitrogen instead of air also a K&N air filter does wonders and is good for lifetime worth every penny. another smart move is to use a fuel system cleaner regularly Lucas makes great products for this try local parts store.

Fuel gauge issues


Sounds like you've got a defective fuel level sending unit. It's in your tank, probably attached to the boost pump assembly. Normally the top of the tank can be accessed via the trunk where you should be able to remove the assembly for replacement. While you're in there, look around in the tank with a very bright flashlight for any debris or pieces from the assembly laying on the bottom.

Horrible gas mileage can be caused by very many things. Try to buy an OBDII diagnostic scanner to figure out what's malfunctioning. Sensors don't last very long, and can wreak havoc on performance and economy.

Poor acceleration, poor gas mileage


I have the same problem as talked about above. 2002 Hyundai accent gsi. HORRIBLE gas mileage. I only get about 320 km per full tank. My driving habits are good. i took it to the garage and they put it on the computer and no error codes showed up. Question: Can a MAP sensor be faulty but NOT show up on the computer diagnostic? I had my O2 sensor checked out and my exhaust, and changed the flex pipe. Car runs pretty good just horrible gas mileage and kinda crappy power. Changed fuel and air filter. Cleaned the fuel system entirely ($80 at garage not $4 bottle).

Anyone ever use a resistor in the MAP sensor?

High fuel consumption


Check the following things: air filter, wheel alignment, and timing belt, all of them if not serviced on time can affect your fuel consumption. I do not think its the heat because I drive my car in Phoenix AZ with temperatures comparable to Dubai and I still get 500+ km/tank.

Good Luck,
