Does petrol affect car performance?

You may be tempted to use lower octane levels to save money at the pump. However, using that lower rated fuel can actually cause your vehicle's engine to run poorly and could damage it, as well as its emission control systems over time.

Do cars run better with a full tank of gas?

Cars have better gas mileage the fuller the gas tank. As the tank empties out, more and more gas will vaporize to fumes to fill up the volume of the tank above the liquid. That means you have less and less gas to burn.

Does less fuel make you faster?

The short answer: Nope. The reason: The common understanding is that going faster burns more fuel and therefore, the slower you drive, the less fuel your car will use, but this actually isn't true. Most cars' peak fuel efficiency occurs somewhere between 50-60 miles per hour.

Does low fuel affect performance?

According to fuel experts at Bell Performance, if you consistently run your car low on fuel, you can wear out the fuel pump prematurely, over-stressing it and making it hotter. The caveat here is that it's more likely to happen if you do this over a more extended period of time.
