In recent years, the quality of gasoline has changed significantly. Most gas stations now offer fuel that is a blend of 90% gasoline and 10% ethanol. While this ethanol-blended gas is suitable for cars, where a tank of gas is typically used within a week or two, it can cause problems in boat motors where the gas may sit for several weeks, months, or even a year.
The issue with ethanol-blended gas in boat motors is a process called phase separation. Over time, the ethanol settles to the bottom of the tank and remains there, even if the tank is shaken.
One solution to this problem is to treat every tank of gas with Mercury's Quick Care fuel additive, which helps prevent phase separation. However, an even better option is to use 100% gasoline, commonly known as Recreational Gas, or "Rec Gas."
Rec Gas is pure gasoline without any alcohol content, eliminating the risk of phase separation. While Rec Gas can still go bad over time, it does not have the same separation issues as ethanol-blended fuel.
With today's highly efficient outboards consuming less gas, it's essential to be prepared for a tank of gas to last longer than it used to. By using Rec Gas, you can prevent future problems and ensure your outboard motor runs smoothly.
In conclusion, if you want to protect your investment and keep your outboard motor running at its best, consider switching to Recreational Gas. It may be slightly more expensive, but the long-term benefits of using pure gasoline are well worth the extra cost. Plan ahead for success, and you'll be able to enjoy your time on the water without worrying about fuel-related issues.
