You might never know if my car is improving.

I will try again after I fill her up when it is hit low fuel light. I will start doing mpg math thing when I reset the trip mileage.

This car don't carry any items. My trunk is empty. Nothing on backseat. I use a/c sometimes during afternoon. I don't slam gas hard for "rabbit jump". Of course, I'm doing 55 mph.

If you think it is silly to keep 3100 instead swap 3800 engine because of gas saver. Well who know... In past 7 years after 9/11 attack. The gas price is keep rising and still going. Right now, it is getting improving go down but I heard it will rise back because of Texas oil problem during weather. I'm not future guy but who know if we might get like $4, $5, $6, $7, $8, $9 or more gallon

There are lot of change during gas price. Some of members sell gp for small car. Hybrid cars look like it is getting grow big. SUV & Truck are getting down. There are lot of small cars around. GM stop making V8 engine (I remember I read somewhere but I can't find link). That's probably reason GM stop make 3800 engine. It seems everyone going to make small engine instead powerful engine. I know it is suck have slow ass engine but everything have been change lot. Sh!t happen I guess. At least I'm not whine about my car mpg. I'm happy as long it is still good enough for 2 weeks instead week when I used be speeding freak.
