Fuel Economy

got 51.98mpg last tank...i kinda killed some of it on my last commute home, i kinda had to rush to catch a store before it closed & i got out of work late...but this proves the car prefers the stock exhaust for best fuel economy

Compared to what? I can pretty much guarantee there are exhausts out there that will get better gas mileage. And then there is always Unobtanium.

compared to the 49 & 50mpg i was getting in better conditions with my custom full exhaust...when your barely using any throttle & staying below 2700rpm...your not pushing that much airflow

i thought i was going to pick up mainly from running a 100cell race cat versus the 2 400cell cats our cars get...i guess i was wrong

that being said...the car was definetly faster on the top end the few times i did floor it with my custom exhaust...but i didn't buy this car to race it

Ah, that is not surprising then. Most exhausts around are meant for the high end, just like most other go fast goodies. Finding parts that will help the low end for a car like ours isn't easy.

Very nice, malibuguy!

I took a 300+ trip on that gas fill (52.746 MPG) and drove 45-50 MPH on rural highways and some open interstates. I was suprised that I was able to get over 50 MPG on the tank using ethanol now. With all my other + 50's I was using non-ethanol. I changed my driving technique a bit to compensate for the loss of energy using ethanol gas. I also use a stabilizer for the ethanol...1/2 to 1 oz. You get around 1-3 MPG less using ethanol blend than RBOB gas. On this present tank I'm taking another shorter trip this week. So far my first 'bar' I got 120 mi and the second was 70 mi! Better than last fill-up. We will see if I can get two in a row...

Cheers!
