You absolutely got the wrong oil.... You should have got the DTE 32, because that's what I use and I ain't never had a problem and all those other people that say they never have problems are lying because they don't use what I use....
Food grade isn't gonna hurt anything, provided you don't disregard the rest of the data sheet when you're interchanging stuff.
At a quick glance, you're DTE FM32 looks to be a respectable fluid for this application. There's some spot where it pulls out ahead, some where it lags, but it's minor. Like, even if you're all wound up about absolute perfection, you don't care about anywhere that the FM32 comes up "shorter". I'd run it with no worries and no looking back, except just one thing........
You're talking about CRAZY different add pack chemistry and how they get to where they need to be. Two totally different chemical soups. No worries about switching, put in the new stuff and don't look back, but stick with it. Fill it up, and go with it until it's gone. If you choose something else next time, fine, but same thing, fill it up, and go with that until it's gone. You're not worried at all about a small "cross contamination", but you don't really want any tangible percentage of "mix". You don't need to flush or anything. You just need to make sure you have enough of one "chemistry" left when you're done, so that they're not fighting each other before they ever get to the slippery bits. For a fairly low demand application like this, it -might- make no difference at all, but again, without any panic, and without any next level cleanups, I'd make a reasonable effort get mostly one or mostly the other at any given time.
I'm not sure how your work works, but if that specific food grade oil comes easier to you than the non-food grade does, I wouldn't hesitate to call that switch permenant. That's just those two specific and exact products though, assuming that the DTE is "right" to begin with. Two data sheets is enough for today.
