Good Stuff

Keeping the Cetane up and the injectors squirting...my 7.3 liter appreciates the attention. I've used this seasonally / periodically for over 8 yrs. Have also used the Stanadyne equivalent. They all do what they say they'll do. DK is a little easier on the wallet which makes it easier to overdose the fuel tank without it hurting my bank account too bad. Diesel fuel contents vary from producer and distributor, DK always brings my visible soot levels down and adds a little more oooomph in the low RPMs. It also makes a noticeable difference in the diesel "smell" coming out of the exhaust pipe. I attribute it to a more complete fuel burn, so less odor and particulates.
