What’s the oil everyone is using in the optimax? I’m new to the optimax, Is the mercury oil the best bet or is ams oil just as good? It’s a 2007 115hp.
I ran the merc oil the 1st 3 yrs on mine, but switched to amsoil 2 yrs ago & won’t go back. amsoil has burned much cleaner & when on sale at Fleet Farm is much cheaper to boot.
Personally, I will only use the oil designed specifically for the Optimax so I don’t have any issues – no reason not to. I’d hate to have thousands of $$ of damage because I didn’t use the recommended oil. I’m sure Amsoil has top quality products, but I won’t take a chance – I’m not a gambler.
