Fuel Additives / Treatments

[james211]

I’m new to the four stroke outboard game, I’m running twin 2016 150 XL’s with low hours. I’m curious what people use for additives at every fill up? I’m meticulous about maintenance so I want to do my best to keep all aspects of the engine in tip-top shape, and most importantly running great!

I use Seafoam, 150ml/20 Litres of fuel. I like the fact that it comes in 1 gallon containers.
