gas stabilizer & tank full/empty for Garage queen/light usage?

Emergency Service Providers in this area change fuel in static equipment every 30 days to prevent the fuel degradation and gumming!

Your climate has more dramatic temperature swings than we have.

So, leaving gas in a vehicle that's unattended is generally not a good thing.

I have read that a fuel tank should be full during some storage to prevent condensation.

So where does this leave you?

Deal with the issue when you actually purchase the car and get advice from others about this matter, but it's probably not a good idea to store the fuel for long periods.

 

Definitely store with the tank full. Excellent information on long term storage is available from Mercedes Benz and the Mercedes Benz Club of America. All vehicles face the same problems irrespective of manufacturer.

 

Use aviation fuel. Its 100 octane but, doesn't break down like regular gas. I put it in my 308, worked on it for 2 years and whammmo she started up after a minute of priming the lines up. I use av gas every now and then but, during the driving season I mix it 50% av fuel and 50% Sunoco 93. I have a small airport near here that helps me out.

Hope this helps.

 

Full tank and fuel stabilizer.... battery disconected while away.

I use this method on both FI & carbs cars and have never had a prolem.

As long as you drive it some every month I think you're fine without StaBil. That much activity should keep the fuel from settling over a long period and it will move gas through all of the small passages in your fuel system. I use stabilizer every year in boats and so on and I've never had a problem but I wouldn't add it if I didn't need to in an FCar fuel system.

I hate the oxy fuel we have here in Denver from October to April and worry about that in the fuel system of older cars. There's not much you can do about that short of unleaded AV gas.

The one thing I would strongly recommend is a battery tender. they work and it keeps some load off of the alternator.

 

we buy VP racing gas for storing cars, it doesn't breakdown and smells like heaven when using it, a little more expensive but it's amazing

 

Why would you use av gas at 100 octane? Using octane above what a FI car is mapped for does nothing for power and clogs injectors.

 

i tought AV gas destroyed the cats and O2 sensors

 

Could be, not sure about that.

 

100 Octane Av gas is a low lead and will indeed cause a car with cats problems. I mix it for my older cars.

 

i don't recommend using it, but i tell people that uses it to mix it.

 

I saw the answer above and would like to point out that the best solution depends on how infrequent you will be using the car.
If infrequent is once a week - once every two weeks then I suggest doing nothing speacial. Furthermore, i suggest you actually run less fuel in the car so everytime you use it you fresh most of it.
If infrequent means hibernation: ie not using the car for months during winter period, then full tank and stabilisant is a good idea. The positive of a full tank is to avoid condensation in tank which leads to rust, nothing else.
Also worry about electrics: battery cutoff switch is a must if you leave you car sitting.

PS. I've been keeping a 911 in another country for a few years now and usually just switch off the car and keep it with low-ish fuel. when restarted, the first thing I do is re-fuel and chekc tire pressure. still servicing every year by the book.
