I've dug around on here and other forums for a while and haven't turned up the answer, so my apologies if this specific question has been answered. I've been using canola oil for quenching my 5160 with pretty good results, but I'm wondering if I could bump the edge holding a bit with a faster quench. I'm thinking of trying the 11 second quench oil from McMaster-Carr. I've had good results with their 28-second stuff on my 4140. But, I haven't been able to find anywhere how many seconds quench canola is. I know the number of seconds comes from how quickly it will drop a particularly-sized ball of nickel from one particular temperature to another particular temperature. So is canola oil (assuming it's fresh and appropriately pre-heated) going to be a faster or slower quench than the McMaster 11-second stuff?
