what fuel additive if any ?

What type do you use if any. I have used sta-bil, seafoam, quick silver and a few more .

I use sta-bil

I use Sea Foam only. Have been for a few years but I only use ethanol free fuel. Zero problems. My boat sits idol
from the middle of June to the middle of Sept and from the middle of Nov until the middle of Feb. After pumping up
the bulb, it cranks like I ran it yesterday.

I only use LUCAS fuel treatment. And I always use 100% pure gas. no ethanol for my combustion engines. Non ethanol may cost a few cents more, but it is cheaper than 60+ dollars an hour marine mechanic fees.

Sea foam for me

Seafoam works, I have worked on small engines for many of years. It loosing up built up carbon quickly. These new 2 cycle chainsaw and line trimmers with the catalyst in the mufflers is when I thought I would try soaking it in seafoam I was impressed with how it broke up all the build up

Sea foam is what I use. Yamaha recommended it for their motor

Star Tron, Sta-bil, etc. lots of good stuff out there.

Seafoam or Stabil is about all I've ever used.

Never used any of it but I keep fresh fuel and if my boat is gonna sit for a month I'll remove fuel line and drain the line by attaching a fuel connector at each end and holding it vertical (this is tedious but the dang fuel lines nowadays wholesale for over $40 and the bulb will maybe last 18 months if you let fuel sit in it 24/7/365). Another thing I do (which is not an issue with the new epa compliant fuel tank caps that let off at 5 psi) is i keep the vent knob on the tank just ever so slightly closed so that slight variations in temperature and a resulting slight expansion and contraction of the fuel doesnt pull any atmosphere and whatever humidity happens to be in the air that day in and out of the tank. And even then if my fuel gets a couple months old I just add some fresh to it. Never had a fuel problem and I burn whatever gas is convenient.

Seafoam has been around for over 50 years because it works

I stand corrected. Sea Foam was manufactured in the 1930's. This was one of the original cans. Nothing last's that long if it don't work.

Sea foam, everytime in every can of fuel I buy no exceptions and no problems.

I have been in the outdoor power equipment business for 35 years and have access to many brands, but in my equipment, I use Seafoam.

Been using Blue Stable Marine with premium gas for years every tank....7 years running heavy use on the motor with no foul ups no major Mech work needed. That's about all i can say. I am sure there are better ways out there. I use Mercury motors.

I'm gonna tell ya what a repair/service tech advisor (mechanic) told me today from one of the major outboard engine companies.

He said do not store your fuel for extended lengths of time with Seafoam in it. The acetone in the Seafoam will destroy the rubber parts in your fuel system if you do. He recommended any of the stabilizers. He said the Seafoam is a great cleaning agent but isn't designed for long term storage in your system, and will cause damage if you do it. I know most of us don't store our boats for long extended periods, but we do other small engines like chainsaws, 4 wheelers, lawn mowers, etc.

I choose to take his advise because of his experience. You may or may not. I prefer Star Tron or Stabil especially if you use ethanol.

Or we talking 2 cycle or 4 cycle or both.

Add Sea Foam Motor Treatment to every tank of marine engine fuel – Just pour it in!

• Sea Foam Motor Treatment works to dissolve and clean fuel deposits and sticky residues from gas and diesel injectors, carburetors, and combustion chambers.
• Sea Foam helps to stabilize stored fuel for up to two years by resisting evaporation, preserving ignition vapors, and preventing the formation of gum and varnish.
• Sea Foam provides high-temp upper cylinder lubricity and helps to protect the entire fuel system from dry out, wear and corrosion.
• Sea Foam only contains petroleum-based ingredients. It does NOT have harsh detergent or abrasive chemicals that can harm your engine. The more you add to fuel, the better it cleans

It is an excellent cleaner. HELPS stabilize. Won't hurt the engine, it's the rubber O rings and parts and rubber spaghetti gaskets in the fuel system that my guy said it hurt. It's your choice. I use Seafoam all the time at the shop. It's a great product, but different products do some specific jobs better than others.
