My boat motor ( 08 225 HO E Tec ) is 10 yrs old and I don't think Ive ever ran an ounce of gas threw it that wasn't treated with 2+4 fuel conditioner and you know what they say , if it aint broke , don't fix it . But , 2+4 is getting hard for me to find and I'm going on a 9 day fishing trip to Toledo Bend this Friday and I only have a couple of bottles . I could drive all the way across town and pay $11.00 an 8 ounce bottle , or I could just use what I have and then start treating with sea foam like I did for years before I bought this motor , or ........... I could just use what I have until its gone and don't worry about treating any gas ? I know none of the gas I put in it will be there but just a couple of day . What do you smart ppl think ?
