The best I've gotten for mileage with my 1996 Nissan was 26.5 MPG. The old epa ratings said 20 mpg highway, I believe. The problem is, now that the U.S. mandates 10% ethanol in all the gas, I'm finding it difficult to even achieve 20 mpg. I didn't think that 10% ethanol could reduce my FE by over 23% (that just doesn't make sense mathematically), so I put a new set of plugs in, changed the fuel filter and PCV filter (in the air-box with the air filter, which was brand new already), yet it still didn't seem to want to get over 20 mpg. In fact, my last tank averaged 19.8 mpg, horrible for a four-cylinder with a five-speed manual. (I never used to get under 22, even if I used the 4x4) Anyone else have any tips for this vehicle? I have a cap on the back, it is light weight (I can lift it on myself), made of aluminum. Still, the thing is like a brick on wheels, not so aerodynamic. I live in Maine, I don't know how many are familiar with the terrain, but it's mostly hills, and steep ones. Overall, I'm a little peeved at the government for putting this moonshine in the gasoline (a scheme to raise gas tax revenues without actually raising the tax maybe?).
