Good commercial quenchant?

I'm planning on purchasing a commercial quenchant, as I'm going to do my own HT in the future. I'll most likely be using ATS34 and 1080. What's a good quenchant for these steels? I'm aware of Tuff Quench and Parks, but it seems they have several different grades.
 
Johnathan - just get some aluminum plates for the ATS-34, no need to oil quench it. You will thank yourself for doing it with plates. The Tuff Quench is supposedly just rebranded houghto-quench G, the slower of the Houghton oils. If you are looking for 5 ga, it's definitely cheaper to get in touch with a Houghton rep. I would look at the fast oil from McMaster-Carr first though, it is far less expensive and fast enough for 1080.

Parks #50 is 99% mineral oil and paraffin.

Make your own and let us know how it works.

While that is technically true, I assume you're joking right? Parks 50 is a 9 second oil - regular mineral oil is at least twice that, no?

If only there were someone selling Parks 50 on our little forum here... :D

Parks 50 would be great for 1080
 
I recently purchased a 5 gallon pail of 11 sec. oil from mcmaster-carr. It was $75.00 delivered. I have used it on various carbon steels including 1095. Although I do not have access to a hardness tester the blades get hard and hold a good edge. I'm satisfied so far although I would like to test hardness both before and after temper to be sure.
 
Mate the best advice I cAN give you is to identify the max speed of quench that your particular material can do without cracking. I don't use thematerials you nominate.
