In response to this:
DO NOT USE REGULAR FUEL IN MOUNTAIN DRIVING ENVIRONMENTS....there is an age old SAAB Bulletin saying not to do this or you can severely damage your engine.
Here is the bulletin. Note that it warns against using LOWER THAN 87 GRADE fuels, rather than your usual Regular. So even though I am thankful for your warning, it appears to be slightly off-target:
To: All Saab Dealers
Attention: Saab Sales Managers
Saab Service Managers
From: Abe Buchbinder
Reference: Engine failures due to low octane fuel available in high-Altitude areas
The Owner's Manuals for both 9-3 and 9-5 advise the owner that their Saab can be driven on fuel grade AON 87-93. In most parts of the country, this is not a problem as typically 87 octane fuel is the lowest grade available. However, in certain high-altitude areas, (above 5,000 feet) lower octane fuel is available. In these areas, the "regular" type of fuel may be 85 octane or lower.
While this low octane fuel may be sufficient to run in low compression naturally-aspirated engines at these higher altitudes, Saab's turbocharged engines with highly optimized engine management systems can sustain severe engine damage if this low-grade fuel is used. Typically an owner may complain of loss of power, severe detonation and higher than normal engine operating temperature.
If the driver continues to operate their Saab under these conditions, the engine may die or seize. Upon disassembly, deterioration of tops of pistons can be seen with scoring of the cylinder walls also evident.
Failures caused by improper fuel are not covered under the terms of the new-car warranty. If such a condition is encountered, your District Aftersales Manager must be contacted.
We ask that during the Dedicated Delivery process as well as during normal service visits that owners be advised that they pay attention to the grade of fuel during refueling, particularly when operating in high-altitude areas and care be taken not to use lower than 87 octane fuel.
Thank you for your attention.
Sincerely,
Abe Buchbinder
