Fuel Power in Stale Gas

[DockHoliday]

My boat has been stored all winter with about 75 gallons of fuel in a 115 gallon tank. I have a fresh jug of FP, and will treat the fuel to clean up any varnish/gunk, absorb any moisture, and to compensate for lost octane.

Should I use a stronger dose than the recommended 1 ounce for every 5 gallons?

Here is what I do and it works.

To save old fuel, put in enough FP to cover the estimated volume left over and then top off with fresh fuel.

This is assuming you did not put FP in it before winter.

Pri-G is the only match for FP-60 I've tried in getting some "go" out of old fuel. And FP is a whole lot cheaper in application.

If FP is used regularily, is it automatically a 'fuel preserver' (eg. for a car driven annually and then stored) or are additional amounts required when the gas is put back into service?

T ,if used at the 1 ounce per 5 gallons rate consistantly it will last a long time in storage.

I use it that way in the yard equipement and stored 5 gallon containers of unleaded 87 octane here over winter with no problems and fuel still smells fresh as opposed to years past with no adds.


The key is having enough mixed well in the system.

Molas suggestion on freshening the fuel is a good one. 1 ounce per 5 gallons should be sufficient, up to 2/5 may be used safely without wasting it.

Can using a "fuel preserver" be eliminated in vehicles driven and stored annually simply using FP for the last tank / 2 tankfulls??

I have a 1975 Torino with a 351W engine which has been sitting for seven years. I do not know how many times it's been started and ran, nor how old the gas is or if any additives were put in to save it. The engine turns over with the starter, very slowly, but I plan on putting in fresh oil and fuel before actually trying to start it. I also need plugs and wires and vacuum lines replaced before I go for that first start.

The tank reads 1/4 full on 27 gallon tank. If I don't have the equipment to drop the tank and flush it and the lines out, can I add a few ounces of Fuel Power, then fill the tank with fresh fuel, then try starting the engine? I may be able to blow the fuel lines clean with compressed air so the fresh fuel can flow. Also planning on emptying the float bowl and cleaning out the carburetor. Any other ideas before I get started with this project?

I hope you get good answers to this. I want to know also. I have a similar situation.

The F-150 is running poorly now with stale gas and I can't get FP immediately, so I'm going to try and resurrect the old fuel with Redline SI-1. Hope it works.

Then I will use either Stabil or FP if it will work as well?
