[GreenKeys] Proper oil to use?

[Greg Miller]

Hello again everyone!
    I have another question:  I recently purchased a 28KSR and it operates 
beautifully.  I got all of the manuals for it and I'd like to do a 
lubrication on it.  I asked a local Greenkeyer that frequents this list, 
Doug KA2WFT, what kind of oil to use.  Doug mentioned that there was a 
thread about the proper oil to use and mentioned that the consensus was to 
use 20 weight motor oil.  However, Doug said he had trouble finding the oil 
in this area.
    Well, I was browsing through the chemical isle at a local hardware store 
and came across 3-in-one brand SAE 20 Motor Oil (item #10045)!  This is not 
the usual 3-in-one oil, but a heavier oil "specially blended for 1/4 HP 
motors and larger" in the usual 3 oz. bottle.
    My question is: does this sound like a good oil to use to keep my "new" 
TTY running smoothly, or will it gum up and give the works constipation? 
Anyone familiar with this product?  It seems to me (a "green" Greenkeyer) 
that its a good match, but...
    If it works, it's pretty cheap and convenient to use!

    Thanks and 73,
    - Greg K2GTM

BTW - I've had the 28 typing away ITTY via my Dell laptop with dialup and a 
HAL ST-6000 perfectly!  What a beautiful thing to watch!
