![]() ![]() Using less throttle to achieve the same rate of acceleration = less fuel consumption = better fuel economy. This added timing gives you, the driver, more torque at the pedal requiring less acceleration to speed up and therefore, reduced fuel consumption. Higher-octane fuel is less prone to pre-ignition otherwise known as engine knock, initiating your vehicle control module to automatically add spark advance or timing. Can the type of fuel you pump affect your fuel economy? Yes, it certainly can. Let’s put the confusion to rest with some real data from tuning experts. This question always seems to be a hot topic on the internet with unclear and even contradictory answers. The DOE also claims that this alone can reduce your fuel economy anywhere from 2% to 17%, which is not ideal. If you have a roof rack on your vehicle with or without a storage box, consider removing that if you’re not actually using it for extra storage. However, keep in mind that A/C is also a huge MPG killer so avoid using it when you can. Now, unless you want to make some major body modifications to your vehicle, try following cars instead of leading and keep your windows up. ![]() This is not as important for city driving since engine RPMs and speeds are low. This is especially important for highway drivers because high-speed driving situations encounter the most aerodynamic drag-the faster you drive, the more air resistance your vehicle must power through. of unnecessary weight removed, you can increase your MPG by roughly 1%.Īerodynamics can also massively affect your fuel economy. Whether you’re an avid enthusiast or mechanic that always carries tools with you “just in case”, you’re a parent with kid stuff scattered throughout the car, or your trunk is like Mary Poppins’ Magic Carpet Bag, you can easily get rid of some unnecessary weight. Simply clearing out your vehicle of any unnecessary weight can improve your fuel efficiency. No, I’m not talking about stripping out your interior to achieve racecar status. Make sure you check your vehicle manual to find out what your manufacturer recommends. This is why manufacturers recommend different oil viscosities for different temperatures. This won’t be the case if you live somewhere warm year-round. Do you live in a warm or cold region? In cold climates with freezing winters, cold oil takes longer to warm up and move freely throughout your engine. In other words, lower-viscosity oils typically flow throughout your engine easier compared to high-viscosity oils.īut you also must consider your specific region. Lower viscosity oils reduce engine friction because they’re easier to pump throughout the engine and have lower churning losses. How so? When it comes to your oil and fuel economy, it’s all about reducing engine friction. Ensuring your vehicle has enough oil is also a critical component of having a fully functional and healthy engine. This is especially important during the winter months when fuel economy naturally plummets because of the freezing temperatures. ![]() While many serious enthusiasts are religious about general maintenance like oil changes and brake replacements, ensuring your vehicle has the proper amount and the right viscosity of engine and transmission oil is another contributing factor to fuel economy. Do You Have the Right Viscosity and Amount of Oil? More work for your engine = more fuel consumption. Why is this? When your tire pressure is below the recommended PSI, your tire’s rolling resistance increases, creating more friction and ultimately more work for your engine to keep your vehicle moving at a certain speed. While 2-3% or even 5%+ may not seem that significant at first, it adds up fast over a couple of months. At 50% recommended tire pressure, you’re looking at a 5-10% lower fuel economy. Department of Energy found that even 75% of the recommended tire pressure resulted in a 2-3% overall lower fuel economy. This may seem like an obvious step, but the negative impact that low tire pressure can have on your fuel economy is more significant than most people realize.Ī study from the U.S. – Final Thoughts Check Your Tire Pressure – Do You Have the Right Viscosity and Amount of Oil? This highly effective method provides even better (and more consistent) MPG which ultimately saves you more time and money otherwise spent at the pump. And most of these steps won’t cost you anything but some of your time.įor drivers who are more serious about achieving the best MPG possible, you can go further with a dedicated fuel economy tune using an HP Tuners interface. Thankfully, there are some simple steps you can take to improve your fuel economy, regardless of what kind of vehicle and commute you drive every day. With rising oil and gas prices continuing to weigh on drivers across the world, everyone is desperate to extend their MPG as much as possible-whether their daily driver is modified or bone stock. ![]()
