    "Chasing MPG in my 80 series Lx450" How I increased my gas mileage.

    I have broke the 300 mile per tank mark towing a small travel trailer (pictured below) before. Not hard to do, but most people panic when the light comes on. I daily drove the 93 I had for 6 months with a non functioning fuel gauge. Once the light came on I had to get gas sometime in the next 3...
