ZDDP Additive (Rislone) in bar/chain oil

[nitesite]

You know, keep around a nice bar oil all tacky plus being good in winter. Bar oil is all the same, right?

My question here is whether anyone else adds a TBL or two of ZDDP additive into every bar oil fill....

My chains and bars seem to love the reduced friction when my pumps don't keep up with me.

Eight bucks of Rislone lasts me an entire summer/fall.

I might have a job coming up where the use of ('actual', not a marketing fad) bio oil is needed, and have considered Canola before. How big of a deal is the issue with the stuff hardening out? I heard it can become a sticky mess.
How long does it take to 'freeze up' your saw? Is there anything that can be done to prevent it, except for dumping it out at the end of the day and run it with regular oil for a bit before storing it? Because I would probably forget to do so at some point... And I definitely don't run my saws every day, sometimes they get stored for weeks, at least.

It's more like months before a chain is stiff if it's not run. Just need to loosen the bar nuts and wiggle it around a little and it's good to go.

Preventing that...I've never bothered, but I bet wiping with some oil or a spray lubricant that stays in place will fix it.

The only annoyance I've found is that more fine saw dust collects under the cover. Not a bunch, but needs a lot more cleaning than otherwise. I've been 100% canola for 10 years - currently running I think it's 7 saws everything from a 10" Makita battery saw to a Husqvarna 385XP with 32" bar.
