The SAAB people who train your dealership mechanics profess what I do --the lower octane=less boost. Less boost= less gas = higher mpgs.
Go argue it with SAAB, not me. This equasion has been in place for a long time.
The fuel engineers from EXXON-MOBIL say this is correct as well.
The SAAB turbo engine (regardless of which fuel is in the tank) makes more than enough power to make the car go down the road.
Now, I know this will sound new to you Mike, but once again, the Trionic engine management system's knock sensor(s) coupled with the computer, a/f mixture and spark timing work to maximize engine output.
More power, more fuel.
More power=more boost=more fuel. Ask your technician what the first thing is that they say to a customer on a "low power" complaint on a 9-5/ or 9-3 or any 16v turbo for that matter.....
Answer: Mr. Customer, Are you using low octane --87--gas in your car ?
Response: Yes, I am.
Tech replies: Mr. Customer, Next fill up use the Premium fuel (in California--91 octane--I believe) and the "lost power" will return. Check the SAAB service manual for a customer with a "torque complaint" and see if I'm not in fact correct here----
Continuing with the treatise, here:
When you use low octane gas--like 87 octane,the knock sensors direct the computer to make changes in the spark timing and the a/f mixture.
Less engine power, less fuel.
Gasoline, premium or regular, has the same energy content---about 115,000 btu's, hence the fuel mileage as a function of the engine.
Keep on sellin' those SAAB's Mike....
