Can grapefruit and lemon trees be sprayed with “year round spray oil .”

Horticultural sprays are normally safe for the plants and the fruit. Another option you might want to consider is neem oil. It is very effective against a variety of pests and is also a fungicide. Neem oil is perfectly safe to use as well. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm ^[1]
