Default Is 15 mpg bad?

I have a toyota tacoma 2003 4x4 xtra cab, with sr5, 4 cylinder. Am I getting the correct gas mileage? I'm not an aggressive driver. As far as weight there is only myself and a tool box in the back. If I am not getting the correct gas mileage, what are some reasons it would be like this? No check engine light, changed oil and air filter. There is no big problems I recognize and by the way this truck only has 60000 miles. I'm mostly concerned because I am a teen paying my own gas and insurance with part time job and want to make sure to get the best of my money.

15 mpg for a 4 cylinder doesn't sound right, how did you come to the conclusion you get 15 mpg?

Well the 4WD isn't going to get as good mileage as a 2WD but it should get a good deal more than 15MPG. I get 20 on a Ranger with a 6cyl and they're not known for good mileage. My son has a Toyota 2WD xtra cab that he gets 25MPG out of. Are you sure you're keeping accurate track of the number of miles driven between fill ups? The number of miles since the last fill divided by the number of gallons to fill it = the MPG.

CI















if you are just driving around town in stop and go traffic, 15 mpg may not be far off. You should be getting around 22 on the hiway. All depends on your driving habits.















check with your toyota dealer and see what he says.

Maybe new plugs and wires would be a good idea.A new O2 sensor can make a difference.

You should be getting at least 20 mpg overall.































Which tires/wheels do you have on? How much air pressure? Are the tires wearing evenly (a check for alignment)? How long are your driving trips?































Also, make sure your brakes are adjusted properly and the parking brake isn't dragging. After driving, place your hand close to the center of each wheel and see if one has a lot of heat coming off it. They should be warm but not too hot. If you have a lot of heat on one, there may be a brake dragging or a bearing with too much preload.































Is there any suspension lift? Any other modifications?































There are a lot of driving techniques that help (and hurt) fuel economy. If you tailgate, that's going to reduce MPG. Powering right up to red lights and stop signs and then using lots of brake is bad for MPG.































Here's a list of fuel economy techniques from Ecomodder:

It doesn't surprise me in real world driving. You should be getting better, but that doesn't mean you will. You are driving a 4 cylinder (a big 2.7 liter, but still 4 cylinders) 4 wheel drive truck.The truck will work harder to pull the weight of a 4 wheel drive vehicle. a lot factor in where mpgs are concerned; driving style, type of roads, geography, etc. I would think 19-20, but I strongly doubt that if you're doing mostly city miles. Great trucks by the way but try getting a tuneup, then see if that helps. I own four Previas with a similar engine (just mounted sideways and slightly amller displacement), and I can get up to 25 mpg highway, but I will drop down to close to 15 in city driving if I have the A/C on and driving normal. Sure the Prev is a van, but the weight is about the same as your truck.

Think about it this way; the truck may be smaller than other typical trucks on the road, but it is still a truck. It's built to tow, it's built to haul, and it's shaped like a truck. It is not aerodynamic by any means. The gearing ratio is still built on a platform for towing, which is not advantageous for fuel economy.































Another thing is that whenever people buy pickup trucks, I encourage them to purchase the more powerful engine models, because smaller engines will have to work harder to haul the truck around. Yes, the smaller engine may get slightly more better mileage than their V6 and V8 counterparts when cruising about +/- 45 MPH, but at higher speeds with crosswind and drag, the 4-cylinder engine is going to work harder. When accelerating from stops in the city, it's working harder. It sucks up about the same amount of gas as a V6 or V8 depending on how hard you accelerate. V6 and V8's also maintain their speeds at highway driving significantly better than 4-cylinder engines.

I would advise you to:















1. Check your tire pressure every 4 days.















2. Make sure your Gas cap is closing properly and tightly















3. Check your Spark Plugs(Often you can switch to more economic ones.)















4. Check your oil weekly, using AMSOIL you can save 6% on fuel cost as well as change your oil and filter once every 25,000 miles.















5. You should use a fuel injector cleaning system like















P.i. Performance Improver Gasoline Additive which you would use every 4,000 miles.































After following these steps you should see a large improvement in your vehicle's mpg performance.
