hey guys, first time poster here long time lurker. I was hoping someone would be able to answer a question I have. I'm a new rider and yesterday I went down to the local caltex to refuel. I saw that E10 unleaded (bio fuel with 10% ethanol), and I asked the guy at the register whether it was okay for bikes to run with it in which he said was fine. However I looked it up on the net, and I've now realised that while this type of fuel can be run with certain brands of bikes, its not approved for use with my kwaka my question is, if i keep running it till i empty the tank will it do alot of damage to the engine? or is a one-off use of this fuel alright? many thanks in advance!
