How to Increase Fuel Economy in a 454

We all know that the economy has been tough these past few years. And with gas prices on the rise, it’s more important than ever to find ways to save money on fuel. One way to do this is by increasing your vehicle’s fuel economy.

Here are a few tips on how you can do this: First, make sure your tires are properly inflated. This can help improve your gas mileage by up to 3%.

Second, avoid excessive idling. If you’re going to be stopped for more than 30 seconds, shut off your engine. Third, use cruise control whenever possible.

This helps maintain a consistent speed and can lead to better gas mileage. Fourth, clean out your car regularly. An extra 100 pounds in your trunk can decrease your mpg by up to 2%.

  • In order to increase fuel economy in a 454, there are a few steps that can be taken
  • Firstly, ensure that the engine is tuned up properly and running efficiently
  • This includes checking things like the spark plugs, air filter, and fuel injectors
  • Secondly, avoid excessive idling as this can use up a lot of fuel unnecessarily
  • Thirdly, try to drive at more steady speeds rather than accelerating and braking constantly
  • Finally, make sure that any extra weight in the vehicle is removed as this will also impact fuel economy negatively

Fuel Injected 454 Mpg

A fuel injected 454 engine can get great gas mileage. This is because the engine is able to burn fuel more efficiently, resulting in less wasted fuel and fewer emissions. The 454 engine was first introduced in the late 1970s and has since become one of the most popular engines for both passenger cars and trucks.

Thanks to its high efficiency, a fuel injected 454 can get up to 30 miles per gallon on the highway.

How Can I Get Better Gas Mileage Out of My 454?

There are a few things you can do to help increase the gas mileage of your 454. Check your air filter and change it if necessary – a clogged air filter can reduce fuel efficiency by up to 10%. Make sure your tires are properly inflated – underinflated tires can decrease fuel economy by up to 3%.

Use the recommended grade of motor oil for your engine – using a lower viscosity oil can improve gas mileage by 1-2%. And finally, avoid excessive idling – idling for more than 10 seconds uses more fuel than restarting the engine.

How Much Fuel Does a 454 Burn?

If you have a 454 engine, you can expect to use between 10 and 12 gallons of fuel per hour. The specific amount will depend on the load that the engine is under and the efficiency of the particular model. Generally speaking, a 454 engine will consume about one gallon of fuel for every 100 miles driven.

How Many Mpg Does a Carbureted 454 Get?

When it comes to carbureted 454s, there is no one answer to the question of how many MPG they get. Depending on a number of factors – including what kind of driving you do, what octane fuel you use, and how well maintained your engine is – your mileage could vary widely. That said, as a general rule of thumb, you can expect a carbureted 454 to get between 10 and 15 MPG.

However, if you’re doing a lot of stop-and-go driving or hauling heavy loads, your mileage will undoubtedly be lower.

What Year is the Best 454 Engine?

There is no definitive answer to this question as it depends on a number of factors, such as what you plan to use the engine for and what your personal preferences are. However, many experts believe that the best 454 engine is from the mid-1970s. This is because engines from this period were generally more powerful and reliable than those from earlier or later years.

If you are looking for a 454 engine for your classic car or truck, then a mid-1970s model is likely to be your best option.


If you’re driving a 454 and want to improve your fuel economy, there are a few things you can do. First, make sure your tires are properly inflated – underinflated tires can lead to decreased fuel efficiency. Second, avoid excessive idling – when you’re stopped for more than 30 seconds or so, turn off the engine.

Finally, keep your speed down; gas mileage decreases significantly as speeds increase. By following these simple tips, you can improve your 454’s fuel economy and save money at the pump!
