Hello everyone!

Not to long ago my friend drove my car and filled it up with gas. Unfortunately she used middle grade gas at the station, which is like 89 octane i think...

I know she isn't the smartes girl in the world, but she is the cutest thing in the world.

Anyhoo, the car has been pinging when I accelerate. I burnt as much fuel as I can and refilled it with 91 octane. It has been like 25-30 miles now and the car is still showing some signs of knocking. Will this go away or do I need to add those octane boosters?

Thanks guys.

 

It will take 3 - 5 tank fulls before it goes away.

 

will a bottle of octane booster help solve the problem quicker?

 

octane booster barely does **** for raising the octane but its worth a shot, just dont give it wot when driving it for a while

 

no need to worry...i did it with my cl type s and the knocking went away after one tank.
