Hello all,

I was reading my owners manual as I prepare for the 2014 summer. Our family just bought a 2012 Moomba Mojo and the manual for my new Mojo and it recommends 89 octane gas. I was talking to other people and they said you can mix and match 87 with 89 octane between fillups and to make sure you put marine stabilizer in the tank each time. I was wondering what people's experience/knowledge on this topic. Would 87 octane gas do considerable harm to the engine? Thank you in advance for any help
