Hi just saw this thread. I just started running B-50 in my 96. After the first tank I acctualy got 1 mpg better than with straight petro. Just changed the filter. It seems like I have better power and I deffenatly have gone further on this tank. I'll let y'all know tomorrow what the mileage difference is on this tank. Dercody how you like being red horse, I'm prime beef
