Fellow Corvette owners,
when storing your cars during the winter months, do you use Sta-bil?
I was told that adding a 20 or 30 oz bottle after filling with fresh gas, will be a good thing before storing.
Any thoughts?
Thanks

I do. However many OZ the bottle says per gallon, plus a splash.

Some say don't bother, some say it's worth it. Don't know, butt all I can say is after 6 months of storage, 4 pumps on the accelerator and it fires right up. For FI cars, no idea.

Your results may vary.

Run fuel without ethanol and the car will be fine without stabilizer. I've never used stabilizer in fuel injected vehicles and never had a problem. On carb'd engines I shut off or cut off the fuel supply and run the crab dry when storing them.

My personal opinion is that for the average winter storage period of 3-4 months it's not really necessary, fuel won't go bad that quickly. Just think of all the new and used cars that sit on car lots for longer than that without a problem. I once bought a brand new 95 Trans Am in January 96 so it sat on the lot for well over a year (it's build month was Sept 94)

I bought a Ram diesel in the dead of winter. Saleshole fired it up in the lot, ran for less than a minute and died. Come to find fuel filter was frozen. Had been on the lot 14 months.

Crap shoot. I swap fuel filters every fall. I run Howe diesel lubricant in both my DD diesels from January to end of march, no issues.

^^^ Diesel is a lot different than gasoline though

Never added anything to my tank - just fill with ethanol free gas which is available at Shell or Canadian Tire

And Costco!

Over in the C7 forum there was a discussion about this and I recall a guy who said he had worked as a chemical engineer claiming that with today's additives you do not need it unless you are storing for longer than one year or on the odd chance you get a bad batch of gas. To me Sta-bil is cheap, so I don't sweat using it. Sure, for the most part it may add no benefit, but on the odd chance you do get stale batch of gas, it is very cheap insurance.

How is the Costco gas? I have never used it.
What grades do they carry?
Thanks

Out of habit I use Stabil, and a full tank of gas. This year is a little different. My Z06 is getting unexpected engine work so once I get it back I'm just going to park it in my garage.

I have been told Sea Foam is much better to use

Gas may not go totally stale in ~4 months of winter storage, but I know that for a number of years when we would park our (carbureted / 2-stroke) snowmobiles for summer, they would NOT fire up the next winter unless we drained the fuel and added fresh gas. You could just SMELL how bad it was after ~8-ish months' of sitting around.

Then we started running Sta-bil at the end of each winter, and the sleds would fire up no problem the following fall/winter.

Fuel injected 4-strokes don't seem nearly as "sensitive" to crappy gas (ie: we could syphon the gas from the sleds and pour it into any of our vehicles, and they would still run) but the fact of the matter is, the gas DOES go bad over time, unless treated, thus, I've been running Sta-bil for at least the last ~10 years, prior to storing my sled or car during the off-season.

This is the first year I'm storing the car without using Sta-bil. let you know how she fires up and runs in the spring.

You ain't gonna notice no difference - it will fire up like a rocket
