Need alternative to horticulture oil

I posted this on the garden clinic forum, but that one is VERY slow and I kinda need an answer. So here I am:)

I have been told that the stuff on my camellia is scale. Here is a pic.

And I know I have aphids on my gardenia bush. So I was told that to get rid of the scale I needed to use horticulture oil. However, I have zero money to go buy it. But I really need to get this taken care of cause I have brand new plants by it that I am scared are going to get "infected". So I was wondering if I could use regular vegetable oil or maybe canola oil as a substitute? Anyone have any ideas?

I had scale on my camellia. I was able to wash it off (with scrubbing). If your plant isn't too big, it's a labor-intensive but inexpensive treatment.

RE: Need alternative to horticulture oil

Over on the Organic Rose Growing forum I believe they say a light vegetable oil can be substituted. You might want to do a search there in case I forgot some caveat or another, though.

I made Cornell formula for my roses using grapeseed oil from my kitchen and it went fine. You're aware that oil can cause serious "burn" on hot sunny days, though, right?
