Common mileage boosters include replacing fuel filter, rotating tires and checking air pressure, adding fuel injector cleaner, installing new spark plugs, checking timing, replacing removable cover with a lighter cover or removing it comletely, disengaging front hubs, replacing timing chain, replacing PCV valve and making sure there are no leaks where it enters engine.

IF IT IS EQUIPPED WITH A CLUTCH FAN, REPLACE IT WITH A FLEX FAN (CHEAPEST) OR BETTER YET A FLEX-O-LITE ELECTRIC FAN. REPLACE THE STOCK EXHAUST MANIFOLDS WITH A SET OF HEADERS. THESE TWO ITEMS WILL NET YOU A 15 TO 20% INCREASE IN GAS MILEAGE. CORRECT TIRE INFLATION IS A BIGGIE. HERE'S THE EASY FORMULA. 1 PSI = 2 % LESS MILEAGE. IF IT CALLS FOR 35 PSI AND YOUR AT 32 PSI, YOUR LOSING 6% OF YOUR GAS MILEAGE. INFLATE YOUR TIRES TO THE CORRECT PSI, WHEN THEY ARE DEAD COLD. A MANIFOLD VACUUM GAUGE, MOUNTED INSIDE THE DRIVERS AREA SOMEWHERE, IS A DIRECT GAS MILEAGE INDICATER. THE LOWER THE READING THE WORSE THE MILEAGE. YOU WILL BE AMAZED HOW THIS DEVICE, IF USED CORRECTLY, WILL INCREASE YOU MILEAGE BY JUST SHOWING THE INSTANT READOUT YOU NEED, TO MONITER, MINUTE BY MINUTE, YOUR FUEL USAGE. GOOD LUCK.
