How to Get Better Gas Mileage On a V8 | Complete Guide

In this modern era, Trucks, engines, and Tonneau cover manufacturers provide gas mileage efficient products to their consumers. With rigid competition, V8 engines are very prominent in this market. They are performing at their best in all aspects. I also have used V8 and found them very vigilant in covering all driving requirements. So in this article, I will share my experience and qualified information regarding How to Get Better Gas Mileage On a V8.

The modern V8 engines may deliver outstanding fuel economy in cities and on the highway. You can do a few things to increase your miles per gallon. Small things add up when it comes to fuel economy. Therefore, it’s crucial to consider how your driving habits and vehicle maintenance routines affect your gas mileage. 

Can V8 be Fuel-Efficient?

V8 engines may accelerate swiftly, but when you run the engine wide open, it will burn the engine exceptionally quickly. This approach will reduce your car’s fuel consumption by 35%. If you’re going to sit for a while, it’s a good idea to turn off the car.

Another aspect is that if you start your car before you leave a traffic signal, you will use far less petrol than if you let it idle for a half hour and burn over half of your fuel limit. A V-8 engine is often more fuel-hungry when idle than a smaller engine, and cranking your car takes roughly the same amount of gas as idling for 10 seconds.

Steps For Getting Better Mileage in V8

In this section, I will discuss a few steps for saving gas or making better the gas mileage in V8:

Step 1: Maintain a Steady Speed

Whenever feasible, stay on the freeways. You are more likely to drive steadily and get higher gas mileage there. Stay on back roads to conserve petrol if your freeway is congested with traffic every morning. Drive as much as you can on highways that let you utilize your cruise control; according to a 2005 test, a V-8-powered Land Rover LR3 earned roughly 14% better gas consumption while utilizing cruise control.

Step 2: Slowly Accelerate the Engine From a Stop

Starting at a stop, like at a stop sign, accelerate gradually yet steadily. Large V-8 engines can accelerate quickly, but when you run with the engine wide open, it quickly burns through your gas. This technique can boost your car’s fuel efficiency by up to 35%. 

Turn off the automobile if you anticipate spending some time seated. Idling can consume up to half a gallon of fuel every hour, but starting your car before a stoplight uses a lot less. The quantity of gas used to start your car and idle it for 10 seconds is roughly the same, with V-8 engines often using more gas than smaller engines.

Step 3: Avoid Extra Luggage

Fill the car with what you need to get the job done or for the people you’re carrying, but don’t overpack. For instance, if you’re not going to use your tools that day, take them out of your V-8 work truck. Your gas mileage may drop by up to 2% if you have to carry 100 pounds more in tools or equipment.

Step 4: Tire Pressure

How far you can go on a gas tank depends on how quickly your tire pressure changes, especially during seasonal weather variations. Low tire pressure causes your tires to roll more slowly on the ground, consuming more gasoline. 

Ensure your tires are inflated to the proper PSI and that their tread isn’t slowing you down more than it should because the tread pattern also influences rolling distance and fuel efficiency.

Step 5: Use Right Fuel

Most cars’ fuel efficiency reaches its optimum around 50 mph before declining as speed rises. Fuel efficiency can be increased by 7 to 14 percent by slowing down on the highway by 5 to 10 mph.

How to Get Better Gas Mileage On a V8 | Tricks to Get Better Gas Mileage

Some of the general tricks to better gas mileage are given below:

Plan your trips

Before you go:

  1. Plan your route to cut down on pointless detours and loopbacks.
  2. Steer clear of busy hours.
  3. Combine errands and visit “one-stop stores” to do many tasks in one location (banking, shopping, etc.).

Watch your speed

Most cars’ fuel efficiency reaches its optimum around 50 mph before declining as speed rises. Fuel economy can be improved by 7 to 14% by reducing highway speeds by 5 to 10 mph.

Drive conservatively

Avoid “jackrabbit” starts, quick acceleration, and harsh braking since these can reduce fuel economy In stop-and-go traffic by 10 to 40%, and at motorway speeds, by 15 to 30%.

Avoid excessive idling

A car engine uses between 1/4 and 1/2 gallons of fuel per hour while idling, but it only needs around 10 seconds’ worth of fuel to restart once it has warmed up. If it is safe to do so if you are going to be stopped for longer than a minute, turn off your engine.

Use a “Fast Pass” on Toll Roads

You can use the express lane on toll highways if you have a pre-paid pass, which reduces or eliminates stops and slowdowns at toll booths.

Avoid rush hour

Use flexible scheduling to avoid traveling during periods of heavy traffic.

Anticipate road conditions

To maintain momentum and prevent needless stop and go, watch the traffic in front of you and “timing” the stoplights.

Use cruise control

On the highway, keeping your speed constant helps you save gas. On slick roads, however, never utilize cruise control as it could result in loss of vehicle control.

Shift gears efficiently

Upshift as soon as it is reasonable to do so if your car has a manual transmission. Use the brakes to come to a stop. To slow the automobile down, don’t downshift.

Drive to warm the engine

Start the car’s engine while it’s cold outside, then drive it usually to warm it up. Driving saves gas because it gets the engine up to working temperature more quickly.

Does V8 Burn More Gas?

V6 engines often have higher fuel efficiency than larger engines of the same capacity. You will typically experience higher fuel economy with a V6 Ram than with a V8 Ram, which is how your V6 Ram differs from its V8 cousin.

Why is a V8 better than a V6?

In terms of stability and handling, V6 engines can provide several benefits over their V8 counterparts. V8 engines often have more power and acceleration than V6 engines.

V8 engines are promoted as being suited for most muscle cars on the market for the same reason. They will be able to provide you with a lot of reliable power when you need it if you plan to use your car mainly for hauling or towing.
