My local BP has done away with Regular Unleaded 91 RON completely and now only sells what they call "Unleaded + up to 10% ethanol" in addition to Super and Ultimate. I filled up my CBF250 with this E10 stuff, unsure if it was appropriate to use a higher RON fuel. The owner's manual says it's OK to use ethanol blended fuel, as long as it doesn't exceed 10%... but they don't recommend it. What's the deal here? Should I fill up with Super instead? OK to keep using E10? Go to a different petrol station? (but then, how long is it before they all do this?) EDIT: After a bit more research, the BP website says that they do not recommend E10 for motorbikes, and further to this, link to the Federal Chamber of Automotive Industries website - http://www.fcai.com.au/publications...atisfactorily-operate-on-ethanol-blend-petrol It's not looking good. Should I be worried?
