Best Long Term Storage Preparation Procedure
« on: June 25, 2014, 08:08:56 am »
For winter storage or long term storage prep methods, I'm finding conflicting information, so what is the best method? 

- Echo basically states to empty the tank, then run it until the engine stops on its own as a result of no fuel. (This is for their chainsaws though, and its carefully written, completely risk adverse cautions & warnings probably doesn't want the saw in a ready-to-start mode.)

- Stihl states to empty the tank, then place a small amount of premixed pure gasoline-oil (ie. Stihl motomix, Echo powerfuel) into the tank, then run the engine for a few minutes to ensure the premix reaches the carb and engine, then stop the engine. (This method makes more sense to me, presuming pure gasoline doesn't break down)

So which method is the best to maximize the life of the carburator (and fuel lines, etc.) ?

I just leave them on the shelf. Fuel holds up well around here.

But the Stihl method works well . . .

There's another common premix fuel called TruFuel that would work well with the Stihl method.

Some people use Coleman lantern fuel

I run 93 ethanol gas. I also use a Klotz mix that stays mixed with alcohol. I have yet to have any problems with mix setting for long periods of time  or separating.

I've tried 2 ways for longer storage. I have dumped and ran till carb empty.  I have left mix in then dumped before use.  I haven't seen any difference in my saws yet.

Mix I use is KL-200 Original TechniPlate Synthetic

Same for me.  That's what I recommend to all my customers.

Good thread, we have just got a reliable source (Sunoco) for 93 non-e fuel. So am in the process of converting to it, so for me this is great! I use the dump and run method also but for saws that are on the for sale shelf I need a way to keep some fuel in them without damage to the saw. Otherwise it is a waste of money to fuel for a demo then dump!

Thanks for the replies guys, sounds like either method works fine, just as long as the gas that was in the tank was treated. I was only asking because I had to replace the zama carb ($30) on my 5 year old echo srm230 trimmer. I don't want carb replacement to become part of my spring routine each year since I have about 6 small engine machines.

Up until last summer, I wasn't really treating the gas at all, but after I got my honda generator for partial backup, I didn't want any voltage fluctuations or drops as a result of bad or deteriorating gas. So now all my gas is treated with stabilizer and ethanol treatment as soon as it's purchased.

Some areas, gas storage is a real problem and other areas, gas-oil is OK after several years.

Just clean it up .. give it clean filters and put it aside it I need it again ... only drain the fuel if I'm working on it

I've a friend with a lot of chainsaws that drains the bar oil out - for many chainsaws of all brands like to leave their mark on the shelf as a puddle of oil.

Saves on bar oil too.
