Car Miles Per Gallon

I can't make this claim for every car miles per gallon (MPG), but my Saab 900 SE, for sale, has gone from 23 mpg to 33.5 mpg in the city just by upgrading to Iridium Spark Plugs. My other car's miles per gallon barely increased for adding in Iridium plugs, but it more consistently gets 44 on the freeway instead of 42, but the real difference for that car is that it has a lot more power.

I have a few theories for why the above differences exist for the miles per gallon:

You see, the Chevy Prizm, referred to as other above, has already been modified so extensively for getting better mpg, that it is more difficult to get more out of it. I'm sad to say, that as these cars have been competing for which vehicle is faster, since the iridium spark plugs the Saab 900 SE with V6 turbo, is now the front runner. For a long time the Saab could out corner and out drive they Chevy Prizm when it was loaded with stuff because of better torque, but I'm quite excited for this car's miles per gallon boost, and hopefully I can get even more out of the Saab. Ah, one more factor, which boosted this cars miles per gallon: I got it a badly needed new battery! It runs so much better!


Common trouble for your car's miles per gallon:

I know, I know, you probably hear this all the time: don't drive drowsy, but in my recent cross state trip, the only time they Chevy Prizm did poorly - 32 mpg - is when we switched off drivers, yet the new driver who was just sleeping, was no longer awake enough. On the same road, going in the other direction in a hilly area that stayed about the same elevation, and after a night's sleep, I got 46 mpg! You see! Something else I discovered is that going 55 and popping it out of over drive increased the car's miles per gallon from the 44 to the 46 mpg. I'd still rather drive 75 when it's legal, but it was a long construction zone, and curiosity paid off. There's the all the evidence I need. It's not just about being responsible and safe, driving drowsy is expensive!
