Contrary to popular belief, Diesel Fuel does NOT require ANY
Stabilizer... as long as it is Clean, in the first place, and
not sucking water into it, in the second place. Water will be taken out
of the fuel, by the Primary and Secondary Fuel Filters. So as long as it

I have to ask those who are. Like these:

Granted, many sources are biased toward their own products
but looking through multiple sources one can ferret out the
real information they all have in common.
