Unheated quench oil?

Just wondering if my 9-11 second oil would slow down predictably if it were used at say 80* instead of 140*.

And since I haven't said so in a while, I really appreciate all I am learning on this forum. I try to read almost everything written here, since I do believe this is a very well founded, as well as polite and open minded forum. You guys probably don't know how much good you are really doing the knife world. Thanks again.
 
From what i understand, heating it up reduces the shock to the metal, and also increases the viscosity. that is just what i remember, though.
 
Sorry, you need to re-remember.
Heating oil decreases the viscosity. It also makes the transfer of heat more efficient. Many oils can be used at room temp. but heating to 130 is the norm for most. Using it cold won't exactly make it slower....more like less effective.
 
Thank you Stacy, that is what I was hoping against, but I knew it couldn't just be that easy.

Any suggestions for readily available approximately 18 second oil?

thanks Stacy. I was half opposite of right, though.;)
 
McMaster Carr's quench oils are designed to be used at room temperature, according to them. I had the same question as you about their oils, so I called and asked. Took a long time on the phone to get to the right person, but I was finally told that it was "engineered to be most efficient without pre-heating." It seems to work fine without pre-heating it here in Florida. I'm not sure about other quench oils.
