i need to know what oil i should use in my 2005 225 optimax!! i just bought this boat about 1 month ago and the guy i got it from always used mercury oil.. well i am out of what he had left and no one close to me sells mercury oil.. wal mart is the only place the even sells oil close to me.. i went there last night and all they had was pennzoil marine 100% synthetic, quick silver premium plus, and johnson/evinrude.. that is it!! the only other place i could get anyother oil is about a hour awaycan someone tell which of these would be the best for my engine for the time being?? thanks
