You can fuel it up similarly to your car! Personal boats can use the same type of gasoline as your vehicle, including unleaded (87 octane), mid-grade (octane 89), premium (octane 93), and diesel.

Do boats need special gas?

What Type of Gas Should I Use in My Boat? All current outboard, sterndrive and inboard gasoline engines are designed to operate safely on fuel with no more than 10 percent ethanol (known as E10), and under no circumstance should fuel with more than 10 percent ethanol (such as E15 or E85) be used in a marine engine.

What type of fuel do you use in boats?

Two major types of fuel can be used in a large commercial boat: marine gas oil (MGO) and marine diesel oil (MDO): Both of these fuels are considered to be distillate fuels, used primarily in high and medium powered ships. Marine gas oil is comprised of a blend of light cycle gas oil and aromatics.

Should I use premium gas in my 4 stroke outboard?

What is the difference between marine fuel and regular gasoline?

Re: Auto Vs Marine Gasoline

If you own a 4 stroke, for example, the 82-octane works just fine, but for a 2-stroke, you should go for the ethanol-free higher octanes (92 and 93) because the lower octanes tend to detonate. Two-stroke dirt bikes also require a special fuel/oil mix.

Can you run premium gas in a 2 stroke outboard?

That said, your choice of fuel remains critical. Burning 87-octane gasoline in a two-stroke outboard causes carbon buildup that shortens engine life. Dose the fuel with a carbon-cleaning additive or fill the tank with 89-octane or higher fuel.
