My S40 has been idling a little funky lately, I figured it might be time for the fuel system clean up, especially now that they are adding more ethanol into petrol, which is something that carbureted engines are not taking kindly.

I bought a can of the "Liqui Moly Motorbike Speed Additive Shooter" and poured into the tank. The engine really came to life, it is running and idling perfect, and according to the butt dyno it feels like it has a bit more pep!

I much recommend it.
