Fuel treatment

I have never used this before as I have always managed to empty my tank, but this year there will be a time that my boat will be inactive with petrol in the bulk tank. Can anyone advise a product and comments?

I was told - stick it in & then most important run the engine at idle to pull the treated petrol into the carbs/ system etc . No point having good petrol in the tank & bad in the engine !

I fill the tank to capacity. and use quicksilver fuel additive as directed. then run the engine with muffs for 10 minutes to let the treated fuel get into the
engine fuel system and carburettor on the auxillary engine.

On my little two stroke I run the engine with the fuel off so it eventually runs dry, no fuel left in the carb to gum up.
At the start of the year if I have petrol left in the tank I add an octane booster. Never had any trouble so far.

Very good advice!

Briggs and Stratton do a fuel preservative-available from your local mower service centre-as do Yamaha and a few others.They all do the same job as long as you buy the correct product.

Hello
Always mix a liter or so of gas with the quantity of fuel stabelizer then dump it into the tank!
The stabelizer tends to run down the fillhose ad adhere to it not all draining in to the tank.

On a fuel injected engine it should be fogged with a mixture of gas/2str oil/fuelstabelizer from a separete tank for 10/15min before storage.

How long will the boat be laid up? It takes a bit for fuel to go off (a month or two at least.) OTOH, stabilizers won't hurt normal running either, so...

One thing I'd be concerned with regarding an idle boat is phase separation if your local supplier is adding ethanol to the gas. Make sure you have a good filter/water separator, and check it often when running again.

Might explain how a dealer jiggered 2 of my injectors after stabilisation on an optimax, if he didnt do that then

Fuel Set

I've been using this Aussie stuff for years in everything! Suzi 140, V6 Diesel Audi, Volvo Penta MD2030 etc
Not just as a stabiliser but on every fill up. Never seen a drop of water in separator despite leaving a 180 ltr tank half full for weeks on end. I reckon it probably gives me 1 extra hp on the Suzi and improves consumption by 0.2nm/ltr. (also use iridium plugs though)

Check out their website.

No I don't have shares in 'Liquid Engineering' !
