Preheat the oven to 250°F. Line a baking sheet with parchment paper or coat with cooking spray.
In a saucepan combine the sugar, honey, and oil. Stir over medium heat until sugar has dissolved.
Add oats to a mixing bowl. Pour honey mixture over the oats. Add cinnamon and salt. Stir everything together until evenly coated.
Spread the mixture evenly over the baking sheet and gently press down.
Bake for 1 hour. Stir the mixture every 15-20 minutes.
Remove and allow the mixture to cool completely in the pan.
