Or it could be that dogass motor that sits up front. The MRAP and LMTV/FMTVs run off JP8 and they will haul ass.It's a completely dry fuel. No lubricity.
Dunno how much that would affect a 6oh system. But I wouldn't run it in a 7.3, or 24V or 12V's.
An old truck told me once that I'd be fine if I dumped a quart of oil in for every 15 gallons...
IMHO though, there is a reason that army humvee's run like chit. And that reason is JP8.
I bet the injectors don't last long without the lubrication.I've worked on a 06 F550 that belongs to a fuel supply company at our local air port. The truck is not registered so they can't leave the airport to fill it with diesel so it runs on straight JP-8. This truck just idles around the air port all day and never sees over 2000 RPM. In just 7,000 miles the EGR was fully clogged with carbon, it was lighter in color and very dry. Also when enough fuel had leaked past the rings into the crankcase the gasket under the oil cooler and the front cover gasket started pouring oil. The gaskets where brittle and flat. Straight JP-8 would be a bad idea, but I would try it with a good amount of 2-cycle or AFT added to every tank. Also delete the EGR for good measure.
