are a percentage of the fuel’s performance measured against pure (100%) octane. Lower octane gas burns quicker than higher octane, and so require less energy to ignite.

Can you drive with a bad fuel level sensor?
Nothing other than risking running out of gas. Depending on the problem it could be just a little off , it could be that it quits working when the fuel level drops below a certain point, or it could stick and still show fuel when it is empty.
Does gas pump automatically stop when tank is full?
Normally, air flows through that tube while you’re filling and the gas keeps flowing as long as you hold down on the trigger. When that hole gets covered by gasoline (when your tank is full), a vacuum forms inside the nozzle and an automatic shutoff switch gets tripped, turning off the flow of gas with a thunk.
What is the best time to fill up gas?
When’s the best time to fill your tank? You’re less likely to wait in line if you fill up at the end of the weekend, not the end of the workweek. On average, U.S. gas stations are the least busy on Sundays, followed by Mondays. The busiest time to get gas is 5 p.m. Fridays, not surprisingly.
Is 2 year old gasoline still good?
Degradation occurs from the get-go but most gas stays fresh for a month or two without issue. However, gas that is more than two month old is generally OK to use with only minor decreases in performance. Gas that is older than a year can cause issues, like engine knocking, sputtering and clogged injectors.
Why is my fuel gauge dropping so fast?
The float is on a lever that actuates a rotary sensor. As the fuel level gets lower, the angular travel increases relative to the gasoline level change so the level seems to drop faster toward the end. Draw a side view picture to help yourself understand this geometirc effect.
How do you know if your gas gauge is broken?
A faulty fuel gauge sender may cause the gauge to suddenly change positions, or give an inaccurate reading. The gauge may appear to be at three quarters, and then only a few minutes later will change to half full, or vice versa the gauge may appear to be full, only to have the gauge climb higher a short while later.
Is it bad to fill your gas tank all the way up?
Gas topping damages your car. Overfilling the gas tank can cause liquid gas to enter the charcoal canister, or carbon filter, which is designed only for vapor. Gas in the system can affect your car’s performance by causing it to run poorly, and damage the engine, he says.

On its own, old gas has lost some of the potency that would have enabled it to fire an engine, but it’s often safe to use up by diluting with newer gas in the tank of an outdoor power tool or vehicle.
Why does the second half of the gas tank go faster?
The car gets marginally better fuel economy during the last half of the tank due to less weight to drag around. However the difference in fuel economy will be so marginal that the user will not be able to measure it. Do cars use the gas in the last half of the tank faster than the first half? No.
Does gas burn faster when you drive 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.
What is the best speed to drive for fuel economy?
65mphThe Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).
