Description

VP Fuel Stabilizer with Ethanol Armor® prevents problems associated with ethanol-blended pump gasoline. It’s like having an ethanol shield for your engine. Our stabilizer keeps vital engine components clean and running at peak performance. It also ensures quick and easy starts. Most importantly, it helps you avoid costly and unnecessary repairs due to long-term storage. We design its proprietary formula not just for cars and trucks; it's also a great fuel stabilizer for motorcycles, lawn mowers, snow blowers, and generators. In fact, it works in any 2-cycle or 4-cycle gasoline engine. It’s a must if you own a vehicle or small engine equipment that isn’t used regularly.

Our fuel stabilizer bonds with gasoline to stop evaporation. It both stabilizes gas and prevents gum and varnish from forming. When you regularly use a vehicle or equipment, gasoline burns up before evaporating and degrading. However, when gas sits unused in a tank, it breaks down and deteriorates. This process can take as little as 30 days. When this happens, gummy deposits form in the engine. That’s where a high-quality stabilizer helps.

Ethanol is found in most pump gas and is at the root of this problem. The reason is that ethanol absorbs water. Second, water promotes corrosion, which is never good for an engine. In addition, when ethanol absorbs just a tiny amount of water (as small as 3/4-ounce), a process known as phase separation occurs. That’s when the ethanol/water cocktail separates from the gasoline, and never the two shall meet.

What Does VP Fuel Stabilizer Do?
Our fuel stabilizer contains a phase separation inhibitor, eliminating the need to drain fuel before storage. Our technologically advanced formula has a special detergent that cleans gums, varnish, and carbon deposits. It also eliminates spending extra money on high-octane premium pump gas. Our additive is EPA-registered and features a tested and proven anti-corrosion package. The NACE Standards Test for Ferrous Metals uses a 1-5 grading scale to measure the ability to resist corrosion. Both ethanol-free and E10 (10% ethanol) fuel received a 0.7 grade for resisting corrosion. That’s right, less than 1.0. Adding VP Fuel Stabilizer with Ethanol Armor improved the corrosion rating to 5.0-top of the charts! In addition, our stabilizer helps reduce engine heat and extends engine life by lubricating the ethanol in gasoline. This reduces parasitic friction. When you reduce friction, you reduce the amount of heat caused by friction. A camel might love extreme heat; engines, not so much. Another thing to consider is how long it lasts. Our product stabilizes for up to three years (1 oz. per 1 gallon of fuel). By comparison, other major gas stabilizers only work for 12 to 24 months. It’s right there in their product description. Plus, a little goes a long way. One 8 oz. bottle treats up to 80 gallons of gasoline (one ounce per 10 gallons of gas). Research other brands - you'll often find that an ounce of their additive treats five or six gallons of fuel, with some calling for two to three ounces to treat 10 gallons of gas.
