My average is 16 mpg during the summer time and 14 mpg during the winter time, when I have to idle to warm it up a little. I use 89th gasoline all the time and I mostly drive it in the city. The computer is showing an average speed of 17 mph. So basically I'm having the proportion of 14 mpg/17 mph. Anyone wants to post their's ? It seems a little low to me...

This is exactly where the smoke leaks from in my case. A muffler-looking, but much smaller thing, just pass the front axle....

I thank all of you guys for your replies. Yeah, exhaust is gonna be the first thing I'm gonna look at when it gets a little warmer ouside. I'm having 2 small leaks from my exhaust in 2 different spots. There are just too many theories out there about this vibration issue, and I guess I'll have to isolate them one by one. There's also a small shock absorber underneath the engine area(there may be even 2 of them), did anyone try to replace it ?

Hi, so did you guys figured where that annoying vibration comes from ? I'm experiencing the same thing on my '99 RX300 :whistles:
