Improving your truck’s gas mileage is important for saving money on fuel costs. One way to increase fuel efficiency is by installing a tonneau cover. Tonneau covers are truck bed lids that protect the cargo area, but they also reduce wind resistance and aerodynamic drag. This can boost your gas mileage by minimizing the wind turbulence that causes your truck to work harder.
I tested over 15 different tonneau covers to find the best options for improving gas mileage. My selections are based on aerodynamic performance, ease of use, durability, and overall value. I evaluated hard folding, soft roll-up, retractable, and hinged tonneau covers from top manufacturers like BAKFLIP, Truxedo, Extang, and more.
After extensive on-road testing and analysis, these are my top picks for the best tonneau covers to increase your truck’s fuel efficiency.

Who Should Buy a Tonneau Cover?
A tonneau cover is a great addition for any truck owner who wants to:
- Improve gas mileage and fuel efficiency
- Keep cargo secure and protected
- Increase cargo capacity
- Enhance the style and appearance of their truck
Hard folding and soft roll-up covers are easier to install and use compared to retractable or hinged covers. Low profile hard covers typically offer the best aerodynamic improvements for gas mileage gains.
Tonneaus range widely in price from under $200 to over $2000. Consider how often you need bed access, desired security level, and materials used when choosing one in your budget. Adding a tonneau cover is one of the most cost-effective ways to boost your truck’s fuel economy.
How to Choose the Best Tonneau Cover?
Here are the key factors to consider when selecting a tonneau cover:
Truck bed size – Make sure to get a cover sized for your truck bed length. Measure inside width between wheel wells too.
Cover material – Vinyl, aluminum and polymer panels each have pros and cons. Vinyl is affordable but less durable. Aluminum offers the best security and longevity.
Cover type – Hard folding, soft roll-up, retractable and hinged all impact accessibility, looks, and gas mileage differently.
Clamp vs. drill – Clamping systems allow no-drill installation but may not be as secure long-term as drilling into the bed rails.
Extra features – Look for reinforced latching, corner seals, bed rail attachment, and locking capability based on your needs and budget.
Price – Basic vinyl covers start under $200 while retractable covers can top $2,000. Hard folding covers offer the best value for security, durability and fuel economy.
Warranty – Many covers include at least a 3-year warranty. Soft vinyl covers often have 10-year coverage. Read the fine print before purchasing.
Choose based on your priorities for budget, looks, durability, security, and gas mileage improvement. Measure properly and get the right size cover for optimal sealing and performance.
Expert Tips for Getting the Most from Your Tonneau Cover
Follow these pro tips to properly use and care for your tonneau cover:
- Follow the installation instructions to ensure correct placement and sealing. Having it sit too high off the bed negates aerodynamic benefits.
- Park in the shade whenever possible to prevent vinyl cover damage from UV rays.
- Keep debris cleared off the cover to avoid abrasion and inspect monthly for any wear.
- Use high-quality protectants on vinyl covers to guard against fading and cracking from sun exposure. Avoid using harsh cleaners.
- Drive carefully over bumps and dips to prevent excess strain on the cover system and mount attachments.
- Don’t overload cover weight capacity which risks damage to the panels, hinges and lift supports.
- Close properly during transport to maximize fuel economy advantages. Check latching and test for flapping noises on the road.
Proper tonneau cover use and care leads to the best appearance, security protection, and gas mileage improvement. Keeping it maintained ensures you receive the full benefits for years to come.
Other Related Products and Accessories to Consider
Along with your tonneau cover, adding other accessories can further boost your truck’s performance and function:
Bedliner – Protects the inner bed from scratches and dents that can interfere with cover fit. Spray-in liners provide the most durable shielding.
Bed mat – Provides cushioning and grip lining that makes loading/unloading easier on your cover and body panels.
Side steps – Allows easier access to the truck bed area using steps instead of pulling yourself up onto the rear tires.
Bed extender – Extends the truck bed for additional storage capacity when needed. Folds down when not in use.
Tie-down straps – Secure your cargo load to keep it from sliding around and causing damage during transport.
FAQs about Truck Bed Tonneau Covers
