canola oil

"canola oil" means vegetable oil pressed from canola seeds, used in cooking or as basis for biodiesel. It is one of many casual words teens pick up from friends, social media, music or sport, and on its own it carries no particular warning. If you hear your teen use it, it is fair to ask what they mean by it in their friend group, since meanings drift quickly. Asking out of curiosity rather than alarm tends to keep the conversation open and useful.

"canola oil" is informal English meaning vegetable oil pressed from canola seeds, used in cooking or as basis for biodiesel. It is mainly heard in Australian or New Zealand English. A more formal or neutral equivalent would be something like "vegetable oil pressed from canola seeds" expressed in standard vocabulary. A common mistake is to assume "canola oil" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing. If you are a B2 or C1 learner, it is useful to recognise this word when you hear or read it, but think carefully about whether the situation really calls for it before using it yourself.
