If you can find an oil that is highly refined, then he shouldn't have a problem. Almost all allergies are from the proteins in the food, and so a highly refined oil is going to be almost all fatty acids and not have the proteins that cause allergens.
I would avoid a health store to buy margarine, unless it specifically is la bled allergen free. Often health stores have specially processed oils that were cold pressed, or extruded to make them more expensive. What this also does is not eliminate the proteins that are allergens.
