I believe Sta-Bil makes a product to spray into your spark plug holes that is liek a fog to coat the while cylinder and not just the bottom. Never used it, don' tknow if a Subaru has enough access to do it.
I'd definately stabalize the fuel. I do in all my antiques. And the Ethanol gas is really BAD in general and especially when a vehicle sets. Alchohol draws moisture.
Most folks seem to think the Marine Sta-Bil does better with Ethanol. It's green instead of red, I think I got a bottle at Walmart.
Hmmmm, might consider the Marine Sta-Bil, but still think I'll go with "regular" Sta-Bil.
I would use a fogging oil for the upper cylinders - comes in a spray can and I think it should have one of the little straws to make getting it in the sparkplug hole easier - and be generous with it. put the old sparkplugs back in the holes to keep dust and moisture out while it is stored. you dont need to buy new ones until you get back and take it out of storage.
fill it up with the high octane (takes longer to break down) and add the fuel stabilizer (i personally would use a stabilizer) make sure it is thoroughly mixed in - as in when you are filling for the last time - add the required amount of stabilizer to the tank (read the directions on the product for the required amount), then fill, then drive the car to it's storage location - this will ensure that the stabilizer is completey mixed in and distributed through out the fuel system.
The reason for filling the tank is to prevent excessive condensation moisture from forming inside the tank and rusting it from the inside out.
jack stands are a good idea - takes the weight off the tires and potentially prevents wheel damage from tires going flat over time...
I think I just might use the fogging oil. I don't have any means to spray motor oil, so it would just be more convenient to use the fogging oil.Anyone have any experience with the fogging oil though????? I'm wondering if it will be fine with the fogging oil...
As for the jack stands ........ place them under the suspension so that the weight of the car is on the suspension. Under no circumstances should you place them under the body/frame and let the wheels hang down with no weight on them for a long storage time. Yes, you can have the tires off the ground (I do with my antique cars, when in storage) to prevent flat spotting.
Depending on where you are storing the car, consider some rodent prevention ... moth balls, Bounce Fabric Softener sheets, a mean starving cat, etc.
Alright, thanks. I will put the jack stands on the suspension then.
And the pest issue just adds something else for me to be concerned about :-\
Put stabil in but run it as empty as you can. The new gas will seperate and water will be in the bottom.
Sell the car and get another when you get back!
As empty as I can? Does half tank sound OK?
How long is "long term" to you?
The biggest problem you face is the effects of bad gasoline. Fuel stabilizer is okay, but will not prevent build up of junk in your injectors and filter.
I would drain all fuel from the tank and filter. Pull the injectors out and get as much fuel out of them as you can. You could leave them immersed in stabilizer with the injector ports plugged.
If your tires hold air okay, don't worry about jacks. That was for old nylon tires. Modern tires will be okay for a year if fully inflated to max pressure.
Rodents can be a problem as someone mentioned. Keep plenty of rat poison around the vehicle, but be prepared to find a dead on in the car later.
I actually built sheet metal skirts that went around the tires on my plane. If you are up on jack stands, you could do the same.
Long term as in years before it gets driven again. I'm doubtful it will be as long as a decade, but 2-5 years is what I'm expecting.
Hmmmm, interesting. A whole year, fully inflated to max? Might not drive it in a year, so that's not an option, sadly.
As for rodents and pests, can you post some pictures, and/or elaborate? I would really like to implement that.
Thanks for the initial feedback! It's a shame not too many Subaru people know about this place!
