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).
Is ethanol-free gas better for your engine?
The short answer is, no, ethanol-free gasoline is not bad for your car. Most cars today can run on ethanol gas blends up to E15 (15% ethanol) and on non-ethanol gasoline. And flex fuel vehicles can handle up to E85 (85% ethanol) without a problem.
Is there a difference between marine gas and regular gas?
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. But the big boats (ships) use some different fuels depending on the engine design and type.
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.
Does ethanol free gas make more power?
Ethanol contains roughly one third less energy than ethanol-free (also known as non-ethanol) gasoline does, which means you will get slightly fewer miles per gallon if you use E10 or E15. The fewer miles per gallon you get is small, but measurable.
How long will non ethanol gas last?
Compared to traditional gas blends like E10 that have 10% ethanol, non-ethanol gas lasts much longer. If stored properly, ethanol-free gas can last up to six months. It is not as likely to succumb to oxidation or evaporation. E10 gas has a three-month shelf life maximum.
Is no ethanol gas better than premium?
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%.
What octane is marine fuel?
We now carry 93 octane “no ethanol” marine gas at the card lock service facility. No Ethanol Fuel for BoatsAbout Marine Gas – At Eli Roberts and Sons we are thankful to offer conventional (87 Oct) unleaded gasoline, commonly referred to as marine gas.
Is premium gas better for outboard motors?
The higher the octane rating, the higher percentage iso-octane in the fuel, which means a smoother burn. It’s important to note that while the higher octane will not give you more standard performance than your engine is designed to give, the lower octane will reduce the expected peak performance of your engine.
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.
Does ethanol free gas gum up?
Since ethanol-free gas lacks alcohol, it is less likely to attract particles of water into the fuel tank. As water is the most common cause of fuel spoilage, ethanol-free gas has an extended shelf life of up to 6 months.
Should I use ethanol free gas in my generator?
Use clean, fresh, unleaded gasoline. Fuel must have a minimum rating of 87 octane/87 AKI. While up to 10% ethanol is acceptable, non-ethanol-premium fuel is recommended. DO NOT use E85, gas/oil mix, or modify the engine to run on alternate fuels.
Is it OK to mix ethanol and non ethanol 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.
