I need more posts so I can see the pictures on here. I have a 1999 Metro and have done a grille block and a lower front spoiler. I had initially completely blocked the grille but have since removed just the one small section in front of the radiator. Since I had only recently just got the car I can't determine exactly how much my mileage has improved. My last two tanks I got 49.1 and 48.9 average. Next up are rear fender skirts and belly pan.
