we need to???"  <VBG>

Ron,
 
Or is it?  "We have this vast infinite wealth of useless knowledge"

Thanks for your information about "shaking" the fuel jugs before using.
As usual you all have a vast knowledge of a lot of things....Don


Yeah, some of us have vast knowledge on subjects.  For some, the
knowledge is only half vast.  <VBG>

I will use about 20-30 case of 2-c and 4-c fuel a year, in both pattern
and sport planes. I know that the fuels should be well mixed and should
stay that way but....
 
On multiple occasions I have had engines run fat or smoky (both 2 and 4
-c) when I switched to a "fresh" new can of of fuel. Clearing that tank
of the fuel that was in there and refilling with fuel that had been
shaken, produced a normal run.  Not talking about first run of the day
either.
 
Since then I stopped fitting a new bottle every time and began to use a
permanent bottle/can on the flight-box and fill from a new can. Never
happened again. I think that some oil or higher oil methanol ratio sits
at the bottom - that's where the electric pump pick-up is - and you get
a mix that gives you a sort of bad run.
 
Once I did try lifting the bottle pick up to half way up the bottle and
filled the tank tank that way. It ran normally again. Call it my
imagination, tell me it can't happen scientifically, but I'll shake my
fuel and also transfer to another can before I use it. 
 
To answer the original question it does not seem to cause any harm to do
so.(Shake it, that is!)
 
Regards, 
 
Eric.
 
P.S. A can that has been opened and 2/3 of the fuel used, sealed and
then left for a year, seems to lose its Nitro content and give similar
results.

I don't, But I've only been flying 4 years.  I got bad fuel once, so I
switched brand and never happened again.  What fuel are you using?  I
just pulled the gallon out of the case and fly.  :)

Someone who has been racing rc cars for over 20 years and is a very
qualified rc guy asked me this week if I had been "shaking" the gallon
fuel bottles to mix the ingredients up before using. I had gotten a bad
gallon of fuel that was just purchased from  a local  hobby shop and in
questioning him about this is when he asked me the question. I have been
doing rc for over ten years and I have never done this or have ever seen
anyone doing this. Do any of you out there in "pattern land" do this?
Thanks.....Don
