From 95 octane to 93 octane

Regular unleaded. 87 Octane

91 is ok to run as long as it's not ethanol!! 95 is better but more expensive...

Could possibly be pinging due to a bad knock sensor. Have you tried a higher octane gasoline to see if that helps?

Hello and welcome to FixYa!

Do you have a good spark? If you do then the problem can be on the fuel pump. If the fuel pump is faulty, there will be no fuel supply to the engine. I strongly suggest that you replace the fuel pump as a first course of action.
Hope this helps and thank you for using FixYa! Have a good one!

If it is the 1.6 FSI model, it is very sensitive to the type of gasoline, it should be octane 97 or higher.
Very commonly, owners of this model use the 95 Octane gasoline, which seems to work ok, but the sensors in the exhaust (yellow motorwarning light) will eventually (can take a few years) clog up and you cant clean it or change the sensor easy either as you need to remove the whole exhaust system.

So either you let VW fix this for you (expensive) or you do it yourself (need a decent garage, equipment and a new sensor).

Hi!!

You should be using regular unleaded. This is "regular" 87-octane gasoline. You have no reason to need gas with a higher octane, it would be a waste, stick to 87.

Good luck!!

YOU NEED TO CAREFULLY REMOVE OR DRAIN OUT GASOLINE BECAUSE GASOLINE OCTANE LOW PETROLEUM GAS OCTANE HIGHER.GASOLINE WILL BURN BUT LOW OCTANE CAN HARM ENGINE.

not sure what octane your useing but but if your useing lower octane try useing higher octane and if your useing higher octane try lower octane gas the gas pump will say the octane rating

Yes, it can, but, there will be no benefit. Corolla engines are not engineered for hi-octane fuel. In other words, the engine will not perform any better with the "best"/most expensive fuel. Stick to 89 octane, that is what the engine is designed for; save your money. The only Toyota cars that "need" super gas is the Supra Turbo and the Celica GTS.

change the gasoline to 95% octane, check the fuel reel and injectors..
