I'd have to look at the bottle to be sure, but IIRC I got 2 gallons of ISO-32 at Tractor Supply. I used it in the gearbox, the apron and in the supplied oil can. I use it all over the place. As for "way oil" I've been cleaning using ATF (transmission fluid) and then a wipe with a towel and some ISO-32. ATF has detergents in it and is good about pulling fine metal off a surface. I use it to clean cylinder bores, the mill table, etc.
