I have tested the theory on the loss of MPG with Optilube. I tried to triple dose and see if I get more regens... Nope... I tried to put in 8 times the recommended, and no loss.
What I have found is that I get about a 1/2 to 3/4 mpg increase using the directed amount and no gain using more. For me, I like the peace of mind knowing that my fuel pump is happy and my injectors are clean in lubed.
My TDI has a DPF so if anyone was to lose mpg's with a bad additive, it would be me.
I have no purchased 4 gallons through the link I posted, for me and friends. All the orders have shipped the same day and the customer service has been great from DFL and from Optilube when I have had questions.
