Probably not wonderful but could be okay.  Some of the more heat-resistant ones might even be okay for regen cooling.  Rudolf Diesel sometimes ran his prototype piston engines on peanut oil.  Don't know that anybody's actually tried it in a rocket.

oldish Diesels ( inline or distributor style injection pumps )
run rather unproblematic on food oils ( sunflower, rapeseed, ..)

discarded frying oil has been used too.

my guess would be that sufficiently heated (viscosity management)
the semi solid oils (palm, ..) should work too.

Nothing heard about olive oil.

( there is a widespread DIY movement to circumvent taxed diesel fuel.)
