With my BMW, I would change the oil, add coolant, and fill the gas tank to the top and add Sta-bil. On the miata, I'm planning to change oil and add coolant. Is it better to empty the tank, or fill it up?

Filling it up takes away space for air that could cause condensation related issues.

I usually fill the car up with 87 + sta-bil and run it for a bit. In the spring I empty that tank and put that gas in a street car.

Yah, I understand the reason for filling it up all the way. In the BMW there was not an option to empty the tank, and I was hoping there was a way to do it without having to empty an entire tank in the Spring.

Oh well, filler up!

Fill it up and add some dry-gas. Don't forget to disconnect the battery, too.

eh...if you left gas in the tank until spring, I wouldn't want to race with it. I either put in about a gallon in the truck each time I fillerup to dilute it with good gas or use it in my mower.

I found the easiest solution for me is just to drive it at the track once a month during the winter. [Smile]

For what it's worth, I just finished reporting for and writing a story on winterization, and according to my sources, the fundamentals have changed a bit due to ethanol.

So, if you have ethanol in your fuel, it is best to have the tank as empty as possible for the winter. Because ethanol is hydroscopic, the less fuel there is in the tank, the less there is to attract moisture.

So, the new wisdom is to drain the tank. If that's not possible, the next best thing is to add a double-dose of the appropriate amount of Stabil (the green marine formula is more hardcore than the red) to as little fuel in the tank as possible. Run the car for about 15 minutes on the double dose, then shut it down.

When spring comes, what little fuel is in the tank will be better because of the double dose from winterization, and will be more easily diluted with fresh gas when spring comes.

I put antifreeze in the coolant, leave the gas tank wherever it was after the last race, put an appropriate a amount of gas stabilizer in the tank; I DON'T change the oil (I'm going to change it before I run it for real in the spring; why do I want to waste the time and money doing it twice?).

Seems to work fine for me, year after year. I start it up and let it warm up once every month or two. It appreciates that I haven't forgotten it.

Nobody mentioned trickle charger or disconnect the battery if it sits for a while, so I will.

Dirty oils' got yucky stuff in it I wouldn't want sitting all winter and why would you change the oil again in the spring? It's ready to go with fresh oil?

Anyone else have input on this ethanol argument. That seems to be a game changer.

My "dirty oil" has one race weekend in it, and is almost clear. Oil that has sat in the motor for five months strike me as being worse for then racing with than leaving my slightly-used oil in for the winter, then changing oil for my first race in the spring.

Ethanol or not, you guy are way over-analyzing this, IMHO. Do one test day, or one track day, (or even one practice session) to get yourself back into it, before your first race, and you've burned through all the "bad" stuff.

But be my guest....

Storing a car with an empty gas tank leads to condensation and corrosion.

If you wanted to drain the gas tank of some or all the gas, what is the best way to do it?

Just jack it up and remove the drain plug in the tank's bottom. I think it's 15mm.

P.S. Seven years with two SM's never drained the tank - never filled it - never used Stabil. Zero fuel issues in the spring. I'm just saying...

How's the car looking? I just received the rear pieces I needed today. Front just needs some massaging other than the fender.

No drain plug on the '99s.

Dry-Gas is essentially just alcohol. Alcohol & gas don't chemically bond to each other well and will eventually separate. It's already near impossible to find gas without ethanol, don't add more alcohol to it.
