Xceed special grade air filter oil
Xceed have added special grade air filter oil to their range. Working really well for onroad and offroad, this very sticky type of oil catches all the finest dirt particles while retaining airflow to the carburetor. Coming in a very specific bright neon yellow color that easily allows it to be seen if the foam filter has enough oil. Comes in a 50m bottle.
