Hello Everyone, Recently, I've come into owning a 1993 Honda Accord DX. With the great hypermiling techniques everyone's been sharing here at this wonderful site, I've been able to get around 35.1 mpg despite the 2008 EPA estimate being 22 mpg. However, I feel strongly I can do much better, like you all easily have. Here's where I really need help; My parents and I have decided to take the car to our mechanic in town for a tune up. Now what exactly should I ask the mechanic to check, repair, or replace that would result in assisting me in preserving or hopefully attaining a higher or healthy fuel economy. Here's what I know to ask to get done; Replace Filthy Air Filter Rotate/Align Tires Install Engine Block heater Replace transmission fluid Replace/Check Engine Oil with lowest viscosity synthetic oil allowed. So, what else should I ask to get checked, repaired, replaced or looked at in order to improve my economy while getting my engine tuned up while at the mechanic? Please post soon! My Accord's appointment is creeping up soon!
