I use diesel kleen when I can afford it..optilube isn't as easily obtained so I settle for less..

I run it in every tank. I buy it by the gallon and mix it 1/2 oz per gallon. A gallon last me about 5 months.

I use both the Opti lube Summer additive and the Winter Additive. It worked out to be less expensive per tank buying both instead of the XPD. I actually recently ran out of the Winter additive and have been using Diesel Kleen.


My DPF and CAT just fell off so I changed the oil and added their oil additive also. I'm going to run the oil 8-10K and send in a sample.


EDIT: I don't believe in any MPG gains. Period.
