How to Get Better Gas Mileage 5.3 Vortec

One of the best ways to get better gas mileage is to trade in your old car for a new one. The new five-point-three liter Vortec engine is more fuel efficient than ever, and it comes with a six-speed automatic transmission that helps you get the most out of every gallon of gas. You can also improve your gas mileage by keeping your car well-maintained.

Regular oil changes and tune-ups will help keep your engine running smoothly, and proper tire inflation will help you avoid wasting energy on rolling resistance. Finally, be sure to use the recommended grade of gasoline for your car; using lower grades of gasoline can actually reduce your fuel economy.

  • Check your vehicle’s owner’s manual to see what the manufacturer recommends for fuel type and octane rating
  • Use the recommended fuel type and octane rating
  • Keep your engine tuned up and in good repair
  • Use regular unleaded gasoline if possible, as it typically has higher octane than premium unleaded gasoline and is less expensive
  • Avoid excessive idling, which can reduce gas mileage by up to one-third under normal driving conditions
  • Drive at moderate speeds on highways; faster speeds can decrease gas mileage by as much as 33 percent at highway speeds above 60 mph

Do Truck Caps Improve Gas Mileage?

There is some debate on whether or not truck caps improve gas mileage. Some say that they do, while others claim there is no significant difference. However, there are a few things to consider that could sway the argument in favor of truck caps improving gas mileage.

For one, truck caps provide aerodynamic benefits. By reducing drag and turbulence, a truck cap can help a vehicle move more efficiently through the air. This can lead to better fuel economy, especially at higher speeds.

Additionally, truck caps can keep cargo from shifting around in the bed of the truck, which can also improve gas mileage by preventing unnecessary weight from moving around while driving. Another potential benefit of truck caps is that they can keep the interior of the cab cooler in hot weather. This can reduce the strain on the air conditioning system, which could lead to improved fuel economy as well.

Additionally, if you regularly transport items in the bed of your truck that need to be kept cool (such as food or beverages), a truck cap can help keep them at a consistent temperature, which could also save fuel by reducing the need for frequent stops to cool down or heat up your cargo. Ultimately, whether or not you see an improvement in gas mileage with a truck cap will depend on a variety of factors including your driving habits and conditions as well as what type of cap you choose and how it’s installed. However, if you’re looking for ways to increase your fuel efficiency, adding a truck cap could be worth considering.


The 5.3 Vortec is a great engine for those who want good gas mileage. Here are a few tips to get the most out of your 5.3 Vortec: 1. Use the right oil- There are many different types of oil on the market, but not all of them are created equal.
