Sadly the rings in the 3rd cylinder went recently in my '94 Metro. Before this, I was getting up to 62.38 mpg. While planning an engine rebuild, I am considering getting the pistons balanced, engine blueprinted and balanced, the crank balanced and knife edged. Should run SMOOTH AS GLASS! Anyways, will shaving 1mm off the head (to raise my compression) give me any mpg's? Any input would be taken into consideration. Thanks for all the good information that this site has given me to get up there in mileage. Even though the gas price went back down. C3.
