Fuel additive for storage

[steve punzo]

Hey guys, putting her away tomorrow. Just a couple questions.  Your time is always appreciated.

1.  Fuel additive? Best brand? Add it before I top off tank? How long should I run it after adding it?

2.  Carpet under wheels? Does this really prevent tires from flattening out, or is it a waste of time?

Thanks fellas

Fuel additive?  Good idea.
Best Brand?  Sta-Bil is the big dog but there are others
Add it before I top off the tank?  Yes, just before.
How long should I run it after adding it?  Just long enough to get the additive laced fuel into the carburetor.  2 minutes?  Less?

Never heard of the carpet under the wheels thing.  Actually, we used to do that to keep the tires from leaving brown stain marks on the showroom floor a very long time ago.  Tire flattening isn't such a big deal anymore now that nylon tire chord is a thing of the long ago past.

If you are concerned about tyres, put the car on jack stands, and cover the tyres with blankets to keep the Sun off the sidewalls.

Stabil instructions are to run the engine for 5 minutes after placing in tank.

I take a bottle of stabil and a measuring cup to the local gas station and add the stabilizer when I top off for the winter. By the time I get to the garage it’s more than 5 minutes and it’s ready to store

I use Sea Foam, some old time wrenches claim this is the best.  Been using it for a few years, good results

 You guys may yell at me but I do not use any kind of fuel stabilizer in any of my stored cars and have never had a problem.   Some have sat as long as three years and start within three tries.  JMHO

I don't use a stabilizer either, but I'm using non ethanol gas. I do put MMO at every fill.

Jim - I also use MMO in the gas.

Jim - I also use MMO in the gas.

Me too....one ounce of MMO and Stabil for every 5 gallons I put in....

MMO is good for that toilet tank float in the 1929 Roadster Vacuum fuel pump...

The key here is that if you are using gasoline
with ethanol, you really should use a stabilizer
for prolonged storage.  If you are using straight
gasoline it's not as critical.

That prevents the ethanol / water (from condensation)
mix from forming a layer in the bottom of the tank.

I use Stabil (the blue bottle, marine grade) since it's
a bit better formulation vs. the standard stuff.

Last winter I decided to go all pro with The Ark and added StaBil and MMO to the fuel before he came off
the road and into the shop, along with a full tank of fresh fuel, Sunoco 93.

The car ran so bad this spring I thought I needed a carb rebuild, it took 3 tanks of fuel before it straightened out.

2 winters ago, my first winter with the car, it stayed outside wrapped up like a giant leftover, 'whatever' gas was in
it stayed in it, and I had no problems at all in the spring.

As always, YMMV.

I'm not doing anything to the fuel this winter.

Neither have I and without issue. Might be different if the car was being stored for longer periods but the relatively short time of one season (more or less), I'm not convinced it's necessary. As always YMMV.
