['No, but if it saves having to drain down the system...']
Surely you'd still have to drain the system before putting in the storage fuel?...If not you would have a difficult calculation of how far you would have to ride with a mix of the two fuels whilst still adding storage fuel before all the E10 was consumed...That could make your brain hurt!!.:laughing: .
Saying that, after draining the E10 the storage fuel looks like a good 'over winter' option...Looking at all their other fuels I would think cost would rule them out for anything other than competition use or, for example, short local runs on a high compression Triumph engine or similar...Ian
