A little off topic. I am sick and tired of getting dark brown fuel at the Petro's an TA's and I am calling the state attorneys office, where every time I get diarreah brown fuel. Last Friday at the West Knox. Petro, the darkest I have seen in a long time. Changed the filter just before fueling, changed it again Monday. Brown at the TA in Prescott,AR. Surprisingly clean at the Petro in North Baltimore,OH and brown at the Petro in Amarillo, just to name a few in past weeks.
