1994 s10 blazer how do you increase gas mileage?

purchase a better car, i own an 02 Blazar and these things just suck gas like you wouldn't believe! and they have a lot of problems with fuel pumps going out i know from personnel experience and $700 poorer and blowing head gaskets...i just saw another 02 in my friends shop and he was installing a Renault engine in his 02, he said the engine cost him $1500. my advice to you is to change the thermostat in your car if it never been changed and flush the system and get rid of that yellow dexcool crap that has been in litigation for many years due to causing blown head gaskets....you must thoroughly flush the system before switching to regular antifreeze.
