What Type of Gasoline Does a Cadillac Use?

[LeBenjamin]

Cadillac uses 95 octane gasoline. Below is relevant information about Cadillac gasoline: 1. Gasoline Octane Rating: The gasoline octane rating represents the ratio of the actual gasoline's anti-knock properties to those of standard gasoline. The higher the rating, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher octane ratings are not necessarily better; the appropriate gasoline rating should be selected based on the engine's compression ratio. 2. Compression Ratio: The primary criterion for selecting gasoline octane rating is the engine's compression ratio, which is also a core energy-saving indicator in modern vehicles. Engine operation consists of a continuous cycle of "intake - compression - combustion - exhaust - intake" in the cylinders. The compression ratio is the ratio of the cylinder volume when the piston is at its farthest and closest points in the stroke.
