I wanted to see what folks have gotten for gas mileage with their Aeros. I have an 03 auto with 105k- bone stock except K&N.
Recently I made a big effort to see how high a number I could generate on a full tank of gas. Here are the numbers:
Total miles: 486
Gallons to fill: 16
Average speed: 37 mph
Avg/miles/gals: 30.3
Temps have been around 70-75 degrees.
The average speed says most of this story. As you can tell I spent as much time on back roads as I did the highway. Excelerating from a stop or low speeds and getting up to speed requires huge restraint. When climbing hills do not excelerate- do that while going down hill or on the flats.
I am going to try a little more on this tank but wow this engine is miserly yet powerful when needed.
I've gotten as high as 36mpg on a ~400 mile tank. This was during a road trip from Chicago to NJ with a 10-15mph tailwind. I'd guess my average speed to be 65mph. I can look up detail of this later, as I have it on a public google spreadsheet.
My total average since I started tracking about 3 years ago is just short of 30mpg. I drive mostly highway and often try to avoid short cold trips by biking. The tanks of mostly city/suburban commuting runs around 27mpg, offest by highway tanks usually around 32mpg.
If you dare run the regular grade octain and take it all highway. I got over 40mpg on my trip from Ohio to Viriginia both ways. And that included a full car for 4 people plus luggage for a 7 day trip. And yes it ran fine on regular.
Higher octane will yield better mileage under high loads. With low octane fuel, if knocking is detected, the ECU will react by dumping lots of fuel and retarding ignition timing to prevent further detonation. Obviously, this won't be as necessary with high octane fuel b/c it is more resistant to detonation.
Lower octane fuel also contains slightly more energy per gallon than high octane fuel. Sooo, if you do all highway driving and never go more than 50% throttle, you should be able to improve MPG by using lower octane fuel. As DaytonMVP said above, the car will run fine on lower octane fuel. You will notice decreased performance though, so if you're a lead foot, even occasionally, it's best to stick with higher octane fuel.
We get 93 octane fuel in Texas, which is what my car usually gets. However, when I go to visit family in the upper midwest, the highest octane fuel you can buy is 91. With 91 octane, I usually see an improvement of about 1 to 1.5 mpg over 93.
Read the owners manual. I wish we had search. The trionic system detects fuel quality in a way or at least load output. And is one of the few ECU that actually do so. It actually has different "subroutines" based on the type of fuel you put in the car. So if you run race fuel for instance your saab will open up a lot better then if you run regular. So if you are going to track the car get it down to as close to E as you can and then fill up with the race fuel at the track and knock your socks off but your MPG will suffer. Most nonturbo cars have no usage for this because they can not increase or decrease the engines efficiency or use a turbo to shove more air in to take advantage of the more potent fuel.
daily driving about 24 avg and when i am going up north for the weekend about 31 that's with the v6. My old grand am got 17 avg with 22 on a good day with way less power. saabd got good mpg
