Does aftermarket exhaust improve fuel economy?
Bottom Line: Adding an after-market performance muffler or exhaust system will improve engine efficiency from 2-10%. Improvements in efficiency can be used to either increase horsepower or improve fuel economy. Whether this efficiency is used to go faster or to get better fuel economy is up to you and your foot!
What parts affect fuel economy?
The following five habits can have a distinct impact on your MPG.
- Excessive Short Trips. Your engine works at its most efficient after it warms up.
- Frequent Cold Weather Travel.
- Heavy Braking or Acceleration.
- High Vehicle Weight or Towing Weight.
- Speeding.
- Fuel Injector Problems.
- Oil Type.
- Poor Maintenance.
Are aftermarket exhausts worth it?
By improving the airflow through the system and decreasing back pressure, aftermarket exhausts reduce the energy wasted in the system having to overcome these pressure problems. This leads to better fuel efficiency. Better sound: Aftermarket mufflers can significantly louden the sound of your engine.
Do you have to buy parts to improve gas mileage?
If your goal is to save fuel for environmental reasons, and you don’t mind the cost, you probably don’t have to think too hard about purchasing the add-ons. But if saving fuel to save money is your primary goal, buying a thousand dollars worth of parts might not be the answer.
How can I improve the MPG on my diesel truck?
Aftermarket items can consist of a performance chip to regulate a power increase. There are many aftermarket parts to consider that will provide your truck with more power, therefore using less fuel to power your diesel motor. Use fuel additives when you fill up at the pumps.
What can I do to reduce fuel efficiency in my truck?
This reduces the truck’s aerodynamics and can cause substantial drag, both of which reduce fuel efficiency. Truck caps improve aerodynamics, as do tonneau covers, which are low-profile bed covers that allow air to flow smoothly across the back of the truck.
Is it possible to get 30 mpg with a diesel truck?
New diesel trucks are getting more expensive, so it makes sense that owners are trying to keep their older rigs on the road longer and get good gas mileage at the same time. It may be possible to upgrade some of your diesel truck parts for better performance and fuel economy. Let’s take a look at how to get 30+ MPG with a Duramax.
If your goal is to save fuel for environmental reasons, and you don’t mind the cost, you probably don’t have to think too hard about purchasing the add-ons. But if saving fuel to save money is your primary goal, buying a thousand dollars worth of parts might not be the answer.
How does a cold air intake improve fuel mileage?
Cold, dense air holds more oxygen—oxygen the engine can use to make more power. A cold air intake will improve throttle response and overall driveability as well, and fuel mileage should increase if you stay out of the throttle.
What’s the best way to improve fuel economy?
A high-flow, reusable filter element is a good place to start your upgrade program—the extra airflow can improve both power and fuel economy. The next step up is a cold air intake system. It replaces the restrictive factory air intake with a high-flow filter element and a larger diameter intake tube to draw in colder, denser air.
How can I improve the mileage of my car?
Changing the fuel filter religiously and using a high-quality fuel system cleaner at regular intervals will keep dirt and junk from clogging the injectors’ tiny openings. Just like getting more air into an engine, getting more of the spent exhaust gasses out of it will improve an engine’s power and efficiency.
