Should I run premium gas in my outboard?

Definitely the fuel

'Premium' fuel has a higher octane rating, which means it combusts more easily. This evidently did not agree with my outboard. It may be fine in newer/different models.

What is the best gas to use in a outboard motor?

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.

What kind of gas do you use in an outboard motor?

Commercial boats will use one of two major types of fuel: marine gas oil (MGO) and marine diesel oil (MDO), both of which aren't usually found at your local marina. MGO is a blend of light cycle gas oil and aromatics, and it may contain waste products like used motor oil.

What octane gas should I use in my Mercury outboard?

What kind of gas should I use in my boat?

Boats use either gas (petrol) or diesel as a fuel, but not both. Generally, small boats will use ethanol-free gas (regular gas) or E10 gas (10% of ethanol in gas), and diesel is not common in small boats. And big boats will use diesel because they need more torque and diesel gives more (than gas).
