I'm sure this is a continued beating of a long dead horse, but I have a 2006 Yamaha HPDI 200 and am confused on all the fuel treatment options. I use Lucas ethanol treatment on every tank, but was curious what others use / suggest.

I am a big fan of sea foam.

I buy non-ethanol gas. The two or three times I've used sta-bil it caused my outboard to run rough.

Sea foam straightened it out and keeps things running well.

Biobor. Been running it since 118 hours on my 09 Yamaha. It now has 367 hours. No fuel/ethanol problems to date. 1 oz per 15 gallons does the trick for me.

None..... (Knocking on wood). 300 hours on mine. Replaced gas hose to Ethanol free hose. No problems yet.

Engine MedX, is the best out there it's crossed between ethanol buster and ring free.

Mines a Mercury so I use Quickleen and Quickcare.

Stabil 360 and Ringfree

05' 200 Optimax I run Stabil 360 and Quickkleen

BIOBOR. Does what Stabil and Seafoam does but also has a lubricant for your cylinders

Quickleen #2 for me. I fish too much to need any kind of storage stabilizer. LOL

Ethanol Free + Seafoam here as well

BioBor or Royal Purple Max Clean...I, too, have no need for gas stabilizer....the gas in my boat doesn't last too long.....

I use seafoam every fill up
