C5 fuel system Nap time ?
Hoe many folks use 'Sta-Bil' fuel stabilizer, My 03 will be asleep till end of March, so I'm debating whether to use it this year ?

My understanding is that any additive needs to be “added” when the fuel system is less than half full because the outboard tank will be empty at that time. If additive is “added” when the fuel gauge is more than half full, it won’t mix thoroughly.

Well I always top off the tank before nap time, which I did last week I've been told that with the tank full, there is less room for moisture, I'll hope for the best. Thank you !

I usually use it, especially if I think I will not be driving the car for around 3 months.

For regular pump gas I wouldn't bother, just fill it full and park it. Don't start the car then until you are ready to drive it again.
For the last 8-9 years, I park mine full of E85 every winter. I run the tanks empty, dump an entire bottle of lucas ethanol stabilizer in it, fill the tanks full and drive it for 10-15 miles to get it mixed in good. Then I park it and don't start it until it is ready to drive again.

I use it in my motorcycles, as they can go 4-5 months without being used. But the Vette? nope. Just fill it up with 93 and don't worry about it. But I do drive mine some in the winter too. I had the Vette out last Saturday for a nice drive down to my buddies to finish up the cage install. And I keep my car on a tender year round when I am not driving it. I usually never go longer than 2-3 weeks without taking it out for a rip. This Sunday it will be in the 50's and I plan to go for a rip and enjoy this Winter 50 degree weather!

I have a Procharger C5 set up fpr E85. I don't trust the fuel guage. The bottle says 1 oz. per 10 gallons. Will I hurt anything if I put in 2 ounces of Red Sta-Bil ethanol treatment and stabilizer?

Several years ago we had aPowertrain engine management engineer speak at our club meeting and he mentioned that toif you use Top Tier gas you did not have to but sta-bil for winter storage.

It should be okay, but something a couple of my "E85 buddies" do for winter is to add some 93 to the mix in the tank as they say it helps stabilize the E85 and makes the first start up after wake up, better. I have no data to back that up, just relaying what they do.
