Bad Gas Mileage

I drive a 98 Ranger XL Splash, 4cyl 2.5L ,5spd. It has new plugs and wires, new air and oil filter. Only 100,000 KM on the engine and has had Synthetic since new. I'm only getting about 300 K to a 85$ tank of gas (1.34$/L). Where abouts would you guys look for issues and how could i improve the mileage.

I think they were talking about me. But I'm not wrong.. to figure out mpg's from metric take your km's driven and divide by litres used then multiply by 2.82 to get miles per gallon. so.... 300/75= 4. 4*2.82= 11.28mpg.

Miscalculation. how many miles(or km). It's amazing what plugs, an oil change, new air filter, and fuel filter does.
