How To Get Better Fuel Mileage In A 4.8 Vortec?

You’re in luck if you want to improve the fuel economy of your 1999 NBS, 35k-mile, half-ton, automatic, two-wheel-drive, 4.8-liter Silverado extended cab. Despite the fact that you may not be content with your current 17.1 mpg, it is still feasible to improve your fuel economy with a few easy actions.

First, ensure that your tires are adequately filled. The optimal tire pressure can improve the fuel efficiency of your car by up to 3.3%. Also, ensure that your engine is in excellent condition and operating correctly. If you need to replace any worn-out components, do so as soon as possible. This will ensure that your vehicle operates efficiently and that no gasoline is wasted.

Consider driving more effectively next. When possible, try to minimize rapid acceleration and braking, as this will drastically lower your fuel economy. Additionally, endeavor to maintain a speed at or below the posted limit. This will ensure that you are driving at a safe and fuel-efficient speed.

Lastly, ensure that you are using the correct fuel type for your car. If you use a fuel that was not intended specifically for your engine, it may not burn as efficiently as it should.

By adhering to these instructions, you should be able to significantly improve your fuel efficiency. In reality, with a little perseverance and work, you may be able to accomplish the 20mpg you’ve targeted. Good luck!
