Just replaced the diaphragm in my mower...............

[NEexpat]

Well the ol Briggs and Stratton was running rough, surging, almost stalling, diaphragm needed to be replaced, ok np, after all, I have installed cruise control and key less entry in my car.

So I go to pick up the diaphragm kit from the "mower guy" and we get to talking, he tells me I should be treating my mower, snow blower gas with Sta-Bil Marine (Blue/Green in color) to offset, neutralize the caustic effects the ethanol in the gas has on the rubber components in the mower.

So the question I have is, would it be prudent to treat my Automobile gas with the same stuff? Can it even be used in Autos?

Is or has anyone tried or been doing this? Any adverse effects? There is talk of E85 (15% Ethanol) being the norm in the future.

Or is all this concern of ethanol eating through every non-metallic part in my car unfounded?

Cheers,
