Did I use too much Power Service?

Asked by Guru9NLZGN Feb 16, 2022 at 10:31 AM about the 1994 Ford F-250 2 Dr XLT 4WD Extended Cab LB

Question type: Maintenance & Repair

Hi, I have a question.  I am new to driving diesel and yesterday I added too
much Power Service to my diesel tanks.  I am using the Power Service in the
white bottle, which is intended for temps above 0 Fahrenheit.  Unfortunately,
without reading the bottle, I added 10 oz to each tank, as I have parallel
tanks on my 1994 Ford F-250 7.3L Diesel idi.  This is twice the
recommended amount for the current temps where I live in Montana.  Am I
going to be okay, or do I need to have my tanks drained?  I just paid $90 to
fill them at the current prices, so that would be bad, but not if this is going to
cause me engine problems.  When I filled the tanks, between the two of
them, they held 25 gallons, so between the two of them, I think they hold just
under 30 gallons.  Another option would be to drive the truck and burn some
out of each tank and immediately refill them to dilute the Power Service.  On
the other hand, maybe I'm ok, cause the recommended amount of Power
Service for temps below 0 Fahrenheit is about the amount I used (well, I
used slightly more than this).  Any replies would be most welcome.

That stuff is to keep the diesel from gelling in the cold. If this is the first treatment then you should be fine but I would burn off about half of it each tank and add fresh fuel back. Too much of it could damage injection pump, injectors and pistons if the loads are high.

Thank you for your advice. I agree, despite what the Power Service rep said. He said it wouldn't be a problem, but I've definitely heard of folks having some of the very issues you mention. I don't believe the former owners used this stuff, so I should be ok burning some off of each tank and diluting it.
