You're right, I did pull off 35 mpg during the motor break in period. I kept it under 70 mph and didn't wind out on the shifts too much. Then....I got a new exhaust system and my milage went down to about 29 mpg. I thought it was the fault of the exhaust but it turns out it's me. I love the sound of the muffler without the baffle and I find I'm winding it out all the time. I cruise most of the time at 80 mph on the freeway (unless Johnny Law is about). I did a few tanks driving like I did at first and my mpg went right back up. It's a trade off.YellowSubxB said:33 MPG is a good start. If you have a 5 speed manual and you drive at moederate speeds, you can easily get that up above 35 MPG, even 38 or 39 on the highway. I've done it. You will find that the MPG will ge better by the 4th or 5th tankful.
