Even new Corvettes, which Chevrolet recommends using premium in, will run fine on regular, if need be. The computers in modern cars will modify the timing, fuel mixture, etc to compensate for a lower grade fuel. Your just wasting money, putting premium in a car designed to run on regular gas.

In general, if you can't really see any improvement in fuel efficiency and performance, you probably shouldn't pay premium. What's more, different cars will respond differently to these fuels, so the only way to find out really is to try out a few tanks' worth and see.

No, it does not. The added weight also helps lower your mileage. Highway mileage (10 mile average) at constant 60 mph no hills WITH Leer cap: 21.50 MPG. If you got more than a 0.5% improvement with a cap or tonneau cover, I'd be surprised.

AFM is good for gas mileage. AFM engines are 5-7% more fuel efficient. However, AFM lifters have a history of failing. Oil consumption has also been a problem.

To put things plainly, it's safe to say that some car mods are worth it, while others offer little if any advantage to car performance. ... You might want to give your car a bit of a boost (pun unintended), but at the same time, you might not want to turn your vehicle into a cop magnet.

Does the 2019 Kia Soul Get Good Gas Mileage? The Soul gets some of the worst fuel economy ratings in the class when equipped with its base engine and manual transmission. Upgrade to the automatic transmission or the turbocharged engine, and ratings improve, but they're still subpar for the segment.

A 4.30 ratio will give you better low end acceleration but also lower gas mileage. A 3.73 ratio will still provide decent acceleration but will also provide a tad better mileage plus give you a higher top end speed. Not that you are looking for a higher top end speed.

In our tests, we've found that in some cars a manual transmission can improve gas mileage by a significant 2 to 5 mpg, compared with an automatic, and can cut a car's price by $800 to $1,200. Manual transmissions often can also improve acceleration, sometimes significantly.

Definitely NOT worth it. If you do NOT want your CAI to provide any power gains, then do NOT get a custom tune. It has a very negative impact on your car by making the car faster, quicker, have better throttle response, have firmer shifts... It's the LAST thing you want from your car.

My experience with K&N filters in my cars, trucks and motorcycles (6 vehicles currently in use) has shown measurable improvements in performance and fuel mileage. These are replacement panel or shaped filters in the factory housings, not in cold-air aftermarket intakes. There is no increase in noise.

Fuel additives claim to improve your car's economy, performance, or both - but do they really work? ... In general, these additives work best on older, high mileage engines that have either been neglected or missed out on regular maintenance. You're unlikely to see any benefit on a newer, well-maintained vehicle.

The premium octane is usually going to sit at around 91, while the regular gasoline is right around 85 to 87. In terms of actual energy produced, including improved MPG, there is actually no real difference between unleaded and premium.

The undercoating might reduce your efficiency by up to one mile per gallon, which creates an additional fuel cost over time that is worth considering. 6. An undercoating is not impervious to damage. An undercoating can provide a hardened layer of protection against dirt and debris that may cause corrosion.

Cars have very optimistic MPG displays. If you're a fuel economy nerd like us, you may like to use your car's “Average” MPG display to see how well you are doing. ... Over the full course of a tank of fuel the MPG average displayed should be pretty accurate though.

I love this product so much. If you can afford to use it with every oil change, you'll find a good result after a year or two. The engine run much smoother and quiet. It has an impact in increasing gas mileage as well.
