I would not try this blend in anything except a cylinder direct fuel injection system.

In an unmodified spark ignition engine designed for gasoline, which utilizes an unmodified carbureted fuel system or a manifold injection fuel system, the mixture will go too lean and likely result in explosive ignition. Explosive ignition will quickly and seriously damage the engine.

In the experiment underway, the engine has an unmodified cylinder direct injection fuel system and an unmodified OEM computer controlled ignition advance system utilizing a knock (preignition) sensor.

To date, there are no adverse affects.
