Unfortunately, there is no definite answer. It depends on a number of factors, including the type of car you have, how much bad gas is in the tank, and how often you drive.

If you have an older car, it’s more likely that bad gas will cause problems sooner than if you have a newer car.

This is because older cars tend to have carburetors instead of fuel injectors. Carburetors are more susceptible to damage from bad gas than fuel injectors. How much bad gas is in the tank also makes a difference.

If there’s only a small amount of bad gas mixed in with good gas, it’s less likely to cause problems than if the tank is almost completely full of bad gas.

Finally, how often you drive also plays a role in how quickly bad gas will affect your car. If you only drive occasionally, thebad gas may sit in the tank for weeks or even months before causing any problems.

But if you’re driving every day, thebad gas will work its way through the system faster and is more likely to cause issues sooner rather than later.
