Rotary Ethanol Shield pairs a protective chemistry with B3C's Combustion Cool Technology to both neutralize ethanol-related problems and dissolve buildup from the tank through the tailpipe. One 24 oz. bottle treats up to 120 gallons of fuel, offering a maintenance-oriented approach rather than a temporary fix.\u003c\/p\u003e\n\n\u003ch3\u003eHow does Rotary Ethanol Shield protect my fuel system?\u003c\/h3\u003e\n\u003cp\u003eThe product counteracts ethanol's tendency to absorb moisture and to promote phase separation. It also cleans varnish and carbon deposits that accumulate in carburetors, injectors, fuel lines, and combustion chambers, restoring cleaner flow and more consistent combustion.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMoisture control to reduce phase separation risk\u003c\/li\u003e\n  \u003cli\u003eCorrosion inhibitors that protect metal components\u003c\/li\u003e\n  \u003cli\u003eDetergent action to dissolve varnish and carbon residues\u003c\/li\u003e\n  \u003cli\u003eCompatibility with fuel system materials and seals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen and how should I use a 24 oz. bottle?\u003c\/h3\u003e\n\u003cp\u003eEach 24 oz. bottle is formulated to treat up to 120 gallons of gasoline, making it suitable for scheduled maintenance or seasonal storage preparation.

Rotary Ethanol Shield 24 Oz. is aimed at owners of cars, motorcycles, small engines, marine craft, and recreational vehicles that use ethanol-blended gasoline. It's useful for daily drivers, classic-car owners prepping vehicles for storage, fleet managers seeking preventative maintenance, and anyone noticing fuel-related roughness or starting issues. Because one bottle treats 120 gallons, it's also economical for workshops and small fleets.
