I see someone else fell for the "Diesel Secret" Nonsense hook line & sinker.
There is NO secret other than the bank account improvement of the sellers.
You can run almost any Detroit 2-stroke on 100% veggie if you thin the fliud down with heat.
I run 70% SVO ( Filtered Used Veggie ) and 30% Pump diesel with no ( Not ANY ) modifications,
reformulations or "Secrets" and my 6V92TA actually runs better in our temperate climate.
A little anti-gunking stuff is added to keep the biologicals at bay but that's all.
I run an Isuzu Diesel NPR truck with the 4BD1T engine on 100% veggie ( no mods at all )
it starts, runs and still gets 17-20 mpg.
Thinning the mix with Kero and Gasoline is the "Only Secret" in that deal. Sorry I almost fell for their
nonsense until I looked at how the "Additive" supposedly works. It turned out that the additive is
not the magic part of the formula. My opinion so whatever...
