First I have to say the poor fuel was from a Valero station with only one Diesel pump. The other fuel was from Citgo's Country Fair and there's not much I have to say for fuel quality, I wasn't checking MPGs on the vehicle then and still am not. People have told me my 6.5 is a loud engine which benefits from a Cetane booster too and it may just be placebo but it at least seems that if I use D.K. it's working a bit smoother. For the record in this post the Diesel Kleen is advertised to improve the lubricity of fuel, clean injectors and boost cetane by up to 5 points at the same time.
