What is the difference between MPG and gas tank volume?

The MPG of your car refers to the number of miles per gallon your car gets when driving on certain road types. The gas tank volume is the amount of gas that your car can hold, which you can find in your owner’s manual.

Can a car with a large gas tank travel farther?

Cars with large gas tanks are going to be able to travel further. They can simply hold more gas. Smaller cars may not be able to travel as far if they have the same fuel efficiency as the car with the larger tank. Since a car has a large gas tank, they have more reserves that allow them to travel longer distances.

Is 10 year old gas 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.

What happens if your gas is older than a year?

Gas that is older than a year can cause issues, like engine knocking, sputtering and clogged injectors. Bad gas can be drained from the tank to prevent damage to the engine. One caveat to keep in mind is that there is no way of knowing how old the gas is when you first pump it into the car.

Can old gas still be used if it’s mixed with new fuel?

Old gas can still be used if it’s mixed with new fuel. Old gas is still usable if it’s combined with fresh gasoline, though your engine might sputter—or may not start right away—because the fuel mixture’s combustibility is lower. To use old gas in gas-powered lawn equipment, fill the fuel tank with one-part fresh gas to one-part old gas.

How long does gasoline last in a container?

Fuels with octane ratings of 91 or more are better refined and contain hydrocarbons that are much more stable than in 87 octane fuel. As a result of the further refinement and stable hydrocarbons, 93 octane fuel can last up to nine months when properly stored. Nine months is a significant increase from 87, which lasts about three months.

What is the difference between 93 and 87 octane gas?

These stable hydrocarbons can last 2-3 times longer than 87 octane fuel. Even in proper storage 87 octane gas can start to degrade in 3 months, 93 octane fuel should last closer to 9 months before degradation is noticeable.

The octane levels in old gas could be a concern only if you’re storing your car for six months or longer, in which case you can add a gasoline additive (or stabilizer) to preserve it.

How does octane affect engine stability?

Engines must use the proper octane fuel to avoid knock and provide reliable operation. A key aspect of gasoline stability is vapor pressure. This is determined by how much pressure builds up inside a sealed fuel container when the fuel is heated to 100°F.
