Thomas to the Rescue.

When Thomas and Diesel are both brought to the Quarry to help Mavis with the work, Diesel lies to Thomas that the Fat Controller plans to scrap the steam engines. The next morning, however, all the diesels take on contaminated fuel and get sick. Thomas is tasked to go around the island and deliver clean fuel to the sick diesels. The Fat Controller congratulates Thomas, calling him a really useful engine and a credit to the railway, and even Diesel has to agree with this.
