How to Get Better MPG in a 2002 Chevy Blazer
- 1). Drive your Blazer sensibly, while avoiding the bad habits which diminish gas mileage. If you drive aggressively, you must stop. Your Blazer wasn't built for sudden acceleration or stopping on a dime. In fact, according to the U.S. Department of Energy, these habits can cost you 33 percent when it comes to fuel efficiency. Thus, avoid tailgating, swerving in and out of traffic and racing from one stoplight to the next.
- 2). Reduce your speed to below 60 mph when driving your 2002 Blazer on the open highway. High speeds and air resistance will begin diminish your gas mileage the faster you travel. This is because the engine must provide more power at higher speeds, which burns extra gas. Use cruise control if you have to in order to regulate your speed. You'll save gas in the long run.
- 3). Allow a trusted or qualified GM mechanic to inspect your TrailBlazer every year. Specifically, examine your SUV's spark plugs, fuel injectors and oxygen sensors. All of these components are related to gas mileage in that they affect how efficiently your engine runs. Have them replaced with new parts if they are malfunctioning. You will see an increase in your gas mileage as a result.
- 4). Check the oil in your Blazer frequently, and change it approximately every 5,000 miles. Consider changing the oil more often, possibly every 3,000 miles, if you extensively use your Blazer off road and/or for heavy towing. Fresh oil will ensure that your engine runs smoothly and thereby boost your gas mileage.Try changing to a premium synthetic oil or low-viscosity oil, as these reduce friction and lessen the burden on your engine.
- 5). Examine your 2002 TrailBlazer's air filter. The air filtration system on your SUV is an important component of your engine's health. An engine that lacks a good supply of clean air due to a clogged filter will struggle to attain good gas mileage. Thus, check your filter when you change your oil and install a new one if the original is dirty or blocked up.
- 6). Pay attention to your Blazer's tires. Check their pressure, even if they don't look as if they're low. Tires that are under-inflated will decrease your gas mileage due to the amount added friction and resistance. Look for the suggested PSI on the sidewalls of the tires, and inflate them to that level. Tires that are inflated to the proper level will improve your gas mileage by up to 3 percent, according to statistics provided by the Federal Trade Commission.
