I like Jantz. They get stuff to me quick. But before I paid $150 for a five gallon pail of Texaco #70, I'd order a five gallon pail of Parks AAA (or the Maxim Oil equivalent) for around $86 (that's how much mine cost including shipping) or Parks #50 (or the Maxim Equivalent) for around $125 (my total cost including shipping). Jantz and Maxim are fairly close, probably about 125 miles apart, so shipping to you should be fairly close to what Jantz would charge.
Iirc, I believe Texaco is a slower quench oil along the lines of Parks AAA. Hopefully KC will stop by and help you out on that.
But it's your call. I just wanted to show you some other options.
