Then you have the other young people (although in the minority) that want a 2 stroke. I had a bloke pick up one a few days ago because his grandfather has one, his father has a couple so he wanted one. These people consider mixing the fuel just part of the procedure of mowing the lawn. I give everyone who buys a mower a plastic 150mm beaker and just tell them to put that much oil in 4 liters of petrol and that is all they need to do. It is easier for people to understand than just words.
