The Passat is designed to use 91 octane gasoline. While 87 octane fuel can be used, this is not recommended, as it could cause engine knock and engine destruction over time.
As many you asked, can you use regular gas in a Volkswagen Passat? In simplest terms, no. Volkswagen vehicles do not require premium gas.
Additionally, what happens if you put regular gas in a Volkswagen? In most cases, the vehicle will run fine, but you may experience less power and a decrease in gas mileage. In more serious cases, you may hear engine knocking or valve chatter because the fuel isn’t burning right. These things could damage your engine and you should take it to your mechanic.
You asked, what happens if you put regular gas in a premium car? Using regular gas in an engine that requires premium could void your warranty. That is most likely to happen if using regular causes severe engine knock or pinging (premature ignition of the fuel, also known as detonation) that damages the pistons or other engine parts.
Correspondingly, can you mix 87 and 91 gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
