Hello all, I'm Steve. My car is a 2001 Pontiac Grand Prix SE
, which has a 3.1 liter engine; not the best place to start for fuel economy, but its better than the 3.8 liter option, I suppose.
Right before I started having problems which led to a crack in the upper intake manifold, I was getting around 22 MPG. I made a number of modifications to it to improve the mileage, I believe most notably some custom bumper extensions which keep a lot of the air from hitting the tire (this modification really helped reduce wind noise at high speed, too) which I crafted out of some extra sheet aluminum.
I've always had an interest in making a vehicle more fuel efficient, but now that my money is tight, I could really benefit from focusing on it.
I've already altered my driving habits to save some gas, and through a combination of that and some power improvements (freeing up intake flow), I've been able to use the automatic transmission's shifting style to save fuel as well (the added power makes it so I don't have to step on the throttle so hard to accelerate at a given rate, and it shifts earlier, keeping my RPM low).
On a different note, I also do web design, and I've combined my interest in that and in cars to create Cars Simplified
