Re: outboard oil question ?
I wanted to know if it ok to mix different brands of tcw3 outboard oil into my oil injected 175 johnson ob .
I use whatever is the cheapest that has the TCW3 rating in my 140hp VRO system. No issues to date.
Just like using different brands of gas, as long as it meets the motors requirements then it should be just fine.
Just my 2 cents though, others may differ in opinion.
