Indeed. The reason for my post is that we have a second tier fuel supplier named GoGas. They have 93 octane non-ethanol, and I'd like to use this in my SP. However, I do know that top tier fuels use more detergents in their fuels; above the EPA standard. I have used Techron for years and it seems to be good stuff. But, I wonder if one or two bottles of it would supply the same detergent levels as found in a tank of top tier fuel? I called the supplier for GoGas and no one could tell me what I wanted to know and they said they would call me back.Keeping the valves (and other surfaces exposed to the combustion gases) clean is not from the presence of ethanol but from the detergents that are blended into the top tier fuels.
The best "detergent" is Techron. As I touched upon above if you can every once in a while run a tank or two of Chevron fuel with Techron can make a noticeable positive difference in how the engine runs.
If you are unable to get Chevron gasoline where you live/drive then consider using a bottle (or two) of Techron (as per direction on the bottle label) every once on a while. My recommendation would be a gas tank or two before a scheduled oil/filter service.
