      Marine Fuel Additives

      Most boats run through a full tank of fuel in about 90 days, give or take. However, the longer unused gas remains in a tank, the more it begins to break down, which can cause threatening fuel lines and engine damage. This is because most fuels now contain high levels of ethanol, which can destroy marine engines. Here’s why - traces of ethanol attack the rubber components of the engine, fuel hoses, and fiberglass tanks, causing long-term wear. It also absorbs water, which causes phase separation in the fuel the longer it sits. This is why Wholesale Marine recommends using marine fuel additives for safety and to prevent damage.

      Our team knows that the best way to prevent damage from unused gas is by using marine fuel stabilizers, which are boat fuel additives that not only keep your fuel from breaking down but to protect your engine from unwanted corrosive damage. That’s a small price to pay to protect one of your greatest investments.

      Shop Wholesale Marine for the Best Marine Fuel Additives

      Wholesale Marine carries the highest-quality boat fuel additives (stabilizers) that will work to protect your boat’s engine for years to come. We carry top brands such as Johnson Evinrude OMC, Mercury and MerCruiser, Sta-Bil, and Starbrite.

      The more powerful engines we’re seeing today may have more strength, but are also prone to breaking down faster. Marine fuel stabilizers such as Johnson’s 2+4 Conditioner or Mercury’s Quickleen, will stabilize fuel, inhibit corrosion, and will also absorb destructive moisture. Starbrite’s very popular Star-Tron and Sta-bil both have additives that prevent the damage caused by Ethanol. Diesel engines need stabilizers and conditioners too, so just ask our knowledgeable staff which boat fuel additives and related products are the best choices for your boat.
