I jumped ship...now what?

There's usually an improvement when an additive is first introduced due to the cleaning affect on the injectors. Constant use is seldom necessary. I've found, after 8-10 tankfulls, I run a dose of Howes or Lucas (personal preference) and mileage will jump up a bit. Of course, this was with my 7.3, I just filled my new truck for the first time last night in anticipation of weighing it today.

Ok, I'll give in to the test result accuracy. Sounds like you did everything to make sure.


365 makes a good point though. How many tanks have you ran and are the results still there, or do you even check?
