Car Modifications to Improve Fuel Efficiency

For anyone searching for ways to improve the fuel economy of vehicles, you are at the right place!
How you drive your car affects the car’s mileage; driving slow, going easy on the gas and brakes, and adequately using all controls are some of the ways we can better achieve fuel efficiency. Also, a properly maintained or well-kept automobile with inflated tires and good alignment can improve fuel efficiency.

So, your good driving habits and careful vehicle maintenance are crucial for keeping fuel efficiency high. However, there are also modifications that you can make to your car to further improve the efficiency.

Real-Time Engine Monitoring

The market is full of plugin devices (plug to the onboard diagnostic system), which can help in streaming data, including coolant temperature, battery voltage, and real-time fuel economy follow-up.

By this, you can easily read and get feedback on your driving habits, like how it affects mileage. If you simply gun it off the line, it will show a swift drop in fuel economy. With that, you will learn to drive safely and slower for better performance.

Vacuum Gauges

Vacuum gauges are one of the lowest-cost tech devices. It helps to provide immediate fuel economy measurements simply by monitoring the manifold vacuum. It works very simply because a higher manifold vacuum results in higher mileage. These efficient dials work like many other dashboard instruments and help you improve the overall fuel efficiency. You can enhance it with basic practice and follow-up vacuum gauges to accelerate fuel performance and maintain a high gauge pressure.

Grounding Cables

Grounding wires, too, play an important role in overall fuel efficiency. It is the central part of the automobile’s electric system. Our cars depend on a complete electric network, including relays, fuses, lights, fans, air conditioners, etc. All these systems are connected to a common ground to get connected to the battery’s negative terminal.

The electric connection loosens over time due to wear and tear and results in increased resistance. Due to this, the system has to work harder, leading to multiple problems, including decreased fuel efficiency.

Pickup Truck Caps

The culprit for reducing trucks’ aerodynamics is the open bed of the vehicle, which is a trap for wind. It could, therefore, result in extensive drag. It can reduce fuel efficiency. However, truck caps can help improving aerodynamics.

Weight Reduction

Weight is another factor to consider as it puts vehicles under tremendous pressure and results in fuel consumption. For the most straightforward calculation, with every 100 pounds in your car, it has to face a 1-2% increase in fuel consumption. That’s means if you own a larger car, then it has to work harder.

You can remove all the heavy items, like roof racks, replacing extra seats, rims with lighter ones, and so on. More so, trying filling the gas tank partially instead of keeping it full along the way could also result in weight reduction.

Fluid Modifications

If you want to improve the fuel performance, consider switching to the lowest viscosity engine oil, and for that, the manufacturers recommended multiple oils. It would be best if you went with synthetic oils, as these have much more stable viscosities with the temperature change, which results in further resistance reduction.

The thinner oil option reduces resistance. Talking about synthetic oils, these tend to be a bit more expensive, but they last longer. The reason is, such types of oils usually don’t break down quickly as compared to conventional ones.

The Bottom Line

A lot of automobile drivers focus on maximizing fuel efficiency, totally neglecting how other car modifications can give a boost to it. You should consider some further modifications, like ditching the roof racks and consider adding a vacuum gauge.
