I own a 2002 Chevy Trailblazer. 6 cyl. vehicle burns alot of fuel. what can i do to get better gas mileage ?

Answer 1

With today's high gas prices, it's worth taking a few minutes out of your day to make minor modifications that will improve your gas mileage. Look at these tips developed by ASE certified technicians for reducing the amount of gas you use.

Note: It probably wouldn't hurt to print this out to share with others.

Keep your tires properly inflated, and check them frequently. Optimum pressure for most cars is 35 PSI.
Use the thinnest viscosity oil that your car's manufacturer recommends (5W-30 for most newer cars).
Keep your engine in tune and make sure the air and fuel filters are clean.
A poorly tuned engine can cost you 15% to 30% in fuel economy.
Don't use premium fuel if your car does not require it (check your owner's manual); using it is an unnecessary expense.
Avoid excessive warm-up time. Modern engines do not require it.
Don't idle your engine for long periods. Turn off your engine when you leave the car or have to wait a long time. The U.S. Department of Energy estimates that for 145 million passenger vehicles idling five minutes per day, approximately four million gallons of gasoline are consumed without going anywhere.
Avoid jack-rabbit starts.
Keep your speed at 55 miles per hour or less whenever possible.
According to the U.S. Environmental Protection Agency and Oak
Ridge National Laboratory, a vehicle loses about one percent in fuel economy for every one mile per hour above 55 m.p.h. that it is driven. A passenger car that averages 30 miles per gallon at 55 m.p.h. could typically get 28.5 m.p.g. at 60 m.p.h., 27 m.p.g. at 65 m.p.h. and 25.5 m.p.g. at 70 m.p.h.
For newer vehicles with aerodynamic designs, close the windows when driving on the freeway.
For older cars with inefficient A/C compressors, use the ventilation system and close the windows, temperature permitting.
Anticipate merging traffic and stoplights; decelerate and accelerate smoothly.
Plan your trips wisely. If you need to go several places, plan a route that allows you to run most or all of your errands in one outing.
Empty the trunk! Extra clothes, overdue library books, tools and the bag of aluminum cans that you have been meaning to take to the recycler all weigh down your car unnecessarily. Each 100 pounds of needless weight will cost up to one-half mile per gallon, on the average.
Car pool whenever possible or practical.
Listen to radio reports for alternate routes around congested areas.
Drive in the highest gear possible, without lugging the engine.
Try to keep your speed constant. Use cruise control when on long stretches of road.

They pretty much get crap mileage anyway but I'm not positive but it should be checked. If your getting a noticeable reduction in fuel mileage than you used to you might want to get your truck hooked up to a scanner that reads real time info that your truck is doing. Like if it's running lean or rich, what rpms it's idling at etc. If they have real time info showing I think they are gonna find that an oxygen sensor is bad, This can cause 30 to 50 percent gas mileage loss when they are bad. It sends info to the computer telling the computer how much fuel to send to the injectors. Also get your fuel filter changed while your getting that checked. A restricted fuel filter makes the fuel pump work harder and try to compensate for the restriction by putting out more gas to the engine.

Answer 3

The others have some really good points about saving gas. The truth is that the Chevy Trailbazer isn't known for it's great gas mileage. They only get about 15 to 17 miles to the gallon on average. So the best bet is to follow their tips and keep a light foot on the accelerator.

Answer 4

You have not provided enough information for an accurate answer. What year of each vehicle? What motors are you looking at? Gas mileage, power and reliability will go to the Chevy almost every time, room depends on interior options. As far as looks, they are in the eyes of the beholder.

Answer 5

You can put a high voltage ignitiol. Something like 5000 volts so that you get a complete burn and put top dollar spark plugs. Also beleave it or not but a good air filter will help too. Something like K&N. If you want to go all out eather have your cylinder heads re ported or buy raceing heads. Not only will you get way more horse power youll also get better fuel efficency.

Answer 6

don't drive so much or buy a smaller car.
