Around a lot of places Sidewinder Strike and Strike fuels are known as engine killers, as they use very low flash point oils that burn off leaving very little lubrication in the engine.
I strip down lots of engines, and you can tell the ones that have run these fuels straight away. Either a red dry scale like coating left over everything, or just plain out and out dry.
Engine wear (especially bearing and crank pin) is greatly accelerated running these fuels IMHO.

If you can source Werks Race Blend, Bones Brew or Byrons locally, I would go down one of those roads.
