★ Top Answer
The manufacturer of the 2005 Cadillac Escalade suggests using premium unleaded fuel with a minimum octane rating of 91. This higher-grade fuel is required by the engine to resist detonation and compress air effectively, ensuring smooth engine performance. Using lower-quality gasoline can lead to timing issues with the pistons, reducing efficiency and fuel economy, and may even cause a ticking noise in the engine. It is crucial to stick to the recommended octane rating to prolong the life of the fuel system and maintain optimal efficiency.
