What type of oil should you use to quench. I heard you can use regular motor oil, if so what kind.

Thanks

Depending on the steel type quenched a lot of different oils will work. Both petroleum based and organic like vegetable oils. Some steels need a faster than oil quench, so that is where the steel type comes into play. Some folks frown on the motor oil quench and I understand it but the point is that it *will* work alright. Just stinks and can flare up into flame and gives off some noxious fumes... I've used a mixture of 30 weight motor oil, a couple gallons of diesel fuel, and a cup or 2 of dish soap in there and it works pretty well. Not the best smelling, but it will do the job on things that won't fit into my salt tube...

If you want some very good quality oil made to do the job, do some research into the commercial quenchants. There are a variety out there and some are pretty expensive, but they also are designed specifically for quenching, which is not something motor oil, transmission fluid, hydraulic fluid, etc. is made for...

Where can I get alot of vegetable oil.

Thanls
