Just wondering what octane I should be using in a Johnson 150... I plan to use a bit of seafoam in the gas when I am not using the boat and I will not store the boat with 87 gas in it.
Should I use 87 89 or 91 octane?
87- 10% ethanol
89-5%
91-0%
I am using amsoil. 50:1
I have read that ethanol is a small engine killer but also that higher octane gas is for high compression engines.
Any advice would be great. I have read a lot of forums and one guy says to use 87 and one says to use 91 so a straight answer would help out.
What do you guys use? I am in Canada so I am not sure what the ethanol ratings are in the us.
