What is the OFFICIAL octane requirement for a '97 Cadillac Catera?
(2010-10-16 14:05:16) 1. Says: I bought it used & came without a manual....2. Says: Pulled directly from manual:Use premium unleaded gasoline rated at 91 octane
or higher for best performance. You may use middle
grade or regular unleaded gasolines, but your vehicle’s
acceleration may be slightly reduced.
It is recommended that the gasoline meet
specifications which have been developed by the
American Automobile Manufacturers Association
(AAMA) and endorsed by the Canadian Motor
Vehicle Manufacturers Association for better vehicle
performance and engine protection. Gasolines meeting
the AAMA specification could provide improved
driveability and emission control system performance
compared to other gasolines.
Be sure the posted octane for premium is at least 91
(at least 87 for regular). If the octane is less than 87,
you may get a heavy knocking noise when you drive.
If it’s bad enough, it can damage your engine. Tag: What is the OFFICIAL octane requirement for a '97 Cadillac Catera?
