4L Bottle Petronas Racing 0W20 7000 Oil.
This is the ultimate oil for Honda GX160 cadet engines. We have been using this oil in all of our cadet engines for over 5 years and have had nothing but great success whilst using it. This oil will increase engine life and is proven to be the best performing oil on our dyno (we have compared a LOT of oils!). We recommend 400ml in Honda cadet engines.
