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.
What is marine fuel octane?
Marine gas is usually 89 or 90 octane ethanol free.
What grade of gas is best for a boat?
As one of the most widely-available and inexpensive marine fuels, E10 is safe for most boat engines. E10 stands for “10% ethanol content” gasoline.
Is there a difference in marine fuel?
Boats use the same gas as cars do; the only difference between the boats and car's gas is the price. A gas at a gas station is a bit cheaper compared to the gas at the marina due to supply and demand.
Can you mix marine gas with regular gas?
Yes you can mix the two. It is clearly better to run Ethanol Free gas in most outboards but if you have E85 or similar in your tank no worries about putting in Ethanol Free. There is one caveat. Mixing will prolong the time the alcohol is in the gas tank.
37 related questions foundHow do you know if gas has ethanol in it?
To determine if ethanol is in the gas:
The ethanol and water will mix and separate out together. If the water level appears to have increased, the fuel contains ethanol and should not be used.
Does non-ethanol gas make more power?
The Differences Between Ethanol and Gasoline
Blending ethanol and gasoline at a ratio of 85 percent to 15 percent (E85), the blended fuel is nearly thirty percent less powerful than pure gasoline. Ethanol is similar in acceleration, power, and cruising ability, but ethanol miles per gallon are less than pure gasoline.
What kind of gas goes in a boat motor?
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).
Can you run marine gas in a car?
Can I Use Marine Fuel Stabilizer In My Car? It is recommended to use 1 ounce of marine formula per 10 gallons of fuel used if you plan to use a marine vehicle on a daily or almost daily basis.
What is marine gasoline?
Marine Gasoil is a fuel composed of various blends of distillates. Distillates are the evaporated components of crude oil during the distilling process, that are condensed from gas state to liquid state. Marine Gasoil can be compared to diesel, but the difference is its higher density and storage requirements.
Can I put 93 octane in my boat?
Personal Boats
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.
Should I run premium gas in my outboard?
Current recommendations are to use a minimum of 87 octane, 89 octane is preferred. There is no additional benefit from using higher-octane fuels, in fact they may cause hard starting conditions in hot weather.
What kind of gas does a MerCruiser take?
MerCruiser engines will operate satisfactorily when using a major brand of automotive unleaded fuel meeting the following specifications: Posted Pump Octane Rating of 91 RON minimum. Premium Unleaded Petrol (PULP 95 RON) is also acceptable. Consult the Owner's Manual for more details.
Can I fuel my boat at a gas station?
Fueling at the gas station
Level your boat; fuel goes in more easily and is less likely to spill if your boat is level. Adjust your bunks/rollers or lower your trailer hitch if necessary.
What is marked gas for?
Overview. Marked fuel is diesel or gasoline fuel coloured to a concentration of 14 parts per million of red dye. This fuel is partially tax exempt to eligible consumers. The fuel tax rate on marked fuel is 4 cents per litre, which is 9 cents per litre lower than the 13 cents per litre on clear fuel.
What fuel does a yacht use?
Nearly every boat on the water today is designed to run with e10 fuel. That means the boat engine will operate with fuel of no more than 10% ethanol. If your boat does not run on e10 fuel then there's a good chance it's a very old engine. If your engine is designed for e10 fuel, it must use e10 fuel.
Is no ethanol gas better than premium?
Improves Mileage
Even if three percent may seem small, it can add up in the long run. Compared to regular and premium gas mixtures, non-ethanol gas is better for your overall mileage.
Is it OK to mix ethanol and non-ethanol gas?
You're all good—mixing ethanol and non-ethanol gas won't affect your car. Most modern vehicles are designed to run on gasoline. Minor changes to this formula, such as ethanol, won't damage your engine and might even improve your gas mileage.
What is non-ethanol gas called?
REC-90 is an ethanol-free, 90 octane unleaded gasoline blend designed for use in recreational/marine engines which can be damaged by the ethanol found in other gasoline blends. It is also usable in some aviation engines [1] and automotive engines, though it has not been thoroughly tested for cars and trucks.
What is the best gas for outboard motor?
What Type of Gas Should I Use in My Boat?

What gas should I use in an old outboard?
Tech Tip: The best solution with old outboards is to run straight gas – if you can find it. Some mechanics may also have the ability to “recalibrate” a carburetor to tolerate E10 (note: gas with ethanol greater than 10% should never be used with any boat engine).
Do you get better mpg with ethanol free gas?
While not as popular as the ethanol blends, pure gas may be preferable for older car engines, as well as boats, lawn mowers or other tools. Ethanol-free gas also gets better fuel economy. However, most drivers use the E10 or E15 blends, with 10-15% ethanol. That ethanol content only reduces gas mileage by around 5%.
Should I use ethanol free gas in my lawn mower?
