is Super unleaded more stable / easy to ignite in 2 stroke?

It's geek heaven. Dozens of diesel engines, all runnable and mostly running, and a telephone display with two manual switchboards and five Strowgers all linked together and usable with a row of vintage phones. Well worth a trip to the wild west.

I just googled up the history around the Bristol Proteus. Irrelevant but fascinating nevertheless. I follow an exotic car forum, mostly populated by sceptics. They constantly witter on about the technical details of petrol X versus petrol Y. In the UK most people just buy it and go..? Life is too short for all that worry!

My understanding is that super unleaded has a lower ethanol content (or even none at all with some brands) so it will keep better (ethanol evaporates faster over time than the petrol content) and also it is less likely to gum up your carbs on a two stroke. I run all my two stroke bikes on super unleaded, and the outboard fuel left over from the boat goes through them as well. I also use super unleaded in my race bike (big four stroke) because it only gets used a few times a year now and I don't want issues with stale fuel in the system. I don't have any fuel issues at all, where I did before someone told me about the ethanol and I changed to super unleaded.

Super unleaded has a higher octane rating than regular fuel. This isn't an issue for any of our engines. Octane slows the burn down so it's a longer release of energy and thus prevents the pinking you can get in higher performance engines, none of which is applicable to anything we use in boats (unless you're into serious powerboat racing....)

Now that is interesting. If it does store better and doesn't gum up the carb I would buy.
