Location: Chisholm, MN | I just got a new boat and motor...115 4 stroke merc. I asked the dealer I bought it from what gas is best to use and he said that you can use 87 with no issues. I've always used premium nonoxygenated in my motors. What do you guys think? Is it safe to put the cheaper gas in my brand new motor? |

| I personally like ( E0) non- ethanol gas if you can get it. Otherwise I would treat with Stabil or Seafoam but then I like to use a higher octane. 115 Yamaha 4-stroke with no problems. My dealer told me to use a higher octane when using E-10 or E-15 gas, reason he said was the Stibil or Seafoam would lower the octane level and that the higher the octane the better the gas would store in tank being treated with Stabil or Seafoam. |

Location: Elko - Lake Vermilion | I have a 2004 Yamaha 200 V-Max and have been using regular unleaded (87 octane) .
The motor runs pretty good and is extremely reliable (880 Hrs.)
It's pushing a 21ft. Skeeter at top speed of 65-67 mph,....... My question is ,........Should I change over to non-oxy fuel, Or keep running reg. unleaded ???
*New powerhead as of 720 hrs.

Location: Dane Country | I use high octane non ethanol in everything I own including lawn mowers and snow blowers. I can get 87 octane without ethanol also. Couples of pennies doesn't make a big deal to me. I look at it I'm protecting my investments. I also only use Sea foam in my fuel.

Location: Grand Marais, MN | E10 87 octane wont kill your new engine, but if you can get non oxygenated, get it. I even put it in my older car and about offset the extra cost with the better fuel economy you get with pure gas. ethanol from a chemical standpoint doesn't really belong in gasoline for a variety of reasons.
that new merc should last you a long time, why risk anything, and especially since most of MN it is easy to find pure gasoline.
