Sure, I would like to avoid PFAS on things that I regularly eat like takeout containers and the like. I'd probably not go for the Scotchgard coating on my next couch as fibers from the couch's fabric usually get flung into the air and I end up breathing in small tiny amounts and it's a high contact thing overall. But if PFAS improved engine seals means my car will last longer, then sure that sounds great.

I'd avoid drinking a glass of motor oil as well, but I still prefer having my car lubricated at the end of the day.
