I want to continue running a synthetic oil any suggestions?
5W-40. It has all the right components neaded for a HEUI injector engine plus
their proprietary blend of liquid moly which helps keep the engine running cooler
and protects against wear.

I just read an article on fuel pressure in the 7.3. I didn't realize the PS's had a pressurized fuel bowl. I know on Cat and Cummins engines, the lift pumps can weaken resulting in poor fuel economy, but didn't think the Ford's had this problem.. Going to clean the sensors on the air delivery system and check the fuel pressure at the fuel bowl.. Maybe I just found my problem.. I'm getting a bit upset about my mileage after reading another forum where guys are saying they are getting 14-16 town and upwards of 20ish on the highway.. Any other suggestions? and, if anyone has any more info, good or bad, from the diesel techs, referencing AMSOIL, or any other synthetic.. send it my way.. I just don't want to spend the $$ for it then destroy an engine or cause other problems, if the oil is not up to standards for the 7.3. Thanks for everyone's help and ideas, greatly appreciated..

Cleaned two sensors (not sure what they are) with carb cleaner, then reinstalled. One is in the turbo tube and has a ceramic center wrapped with what looks like a spring. The other was at the bottom of the alum intake body, lookes like a small match-stick in a horse-shoe shroud. Sorry for know knowing what their proper names are... I also found the exhaust manifold pressure tube was clogged. It's now free flowing to the sensor... Any other suggestions?

what do they blend with diesel for the winter? is it just like diesel kleen or some other fuel?
