I know what you mean. That depends on the plastic, but I'm pretty sure most plastics manufactured these days are resistant to solvents and pharmaceutical mineral oil (which comes in plastic bottles) is too heavy and stable to dissolve the poorer-quality plastics anyway. You would have to use a thin and volatile petroleum distillate like WD-40 or gasoline for damage to occur to them, I think.


Common sense told me I could definitely lubricate this impeller
assembly and with this vegetable oil and use it without harming organisms
like my fish and plants. I have known about vegetable oil hardening in the
past when I was really young and trimming our dog's hair with oster clippers
I lubricated the clippers with vegetable oil as I was sorely lacking
appropriate oil

I found that out the hard way when I was 11 and lubricated my grandma's old pedal-operated sewing machine with olive oil. It worked great for a week or so, then completely seized up. I had to soak the whole thing in gasoline to free it up again :-/
