The Ford 7.3 & 6.0 Powerstroke are the only engines that use a Hydraulic Electronic Unit Injector System (HEUI).
This is quite rare and unique in that is uses the crankcase engine oil to pressurize and "operate" the fuel injector.
Extreme heat helps in creating a varnish causing "injector stiction". It is also prone to erratic injector timing resulting in smoke, low power and poor overall performance.
The 6.0 & 7.3 Powerstroke series has a high occurrence of spool valve stiction, erratic injector timing and premature injector failure. This is an issue in 6.0 & 7.3 engines regardless of the synthetic or regular diesel oil rating or how often the oil is changed.
There are legitimate concerns regarding the hi-pressure oil side of the 6.0 & 7.3 HEUI fuel injection system. No other diesel engine uses its motor oil up to 4000 psi and forces it into a nearly microscopic orifice inside the fuel injector.
The 6.0 & 7.3 engine oil needs help beyond what is currently offered in diesel rated motor oils. ARCHOIL AR9100 is the help it needs to restore and maintain 6.0 & 7.3 HEUI injector systems. As an added benefit AR9100 will reduce friction, prolonging engine life and run quieter.
AR9100 Nanoborate Friction Modifier to lower fluid system coefficient of friction to 0.037, anti-corrosive and EP agent, maintains engine free of deposits and sludge, improves MPG, lowers operating temperatures, double oil drain cycle and increases HP.
AR9100 contains various esters which dissolves carbon and varnish, a solution for POWERSTROKE injector stiction which is the accumulation of carbon and varnish deposits in the injector spool valve resulting in a performance drop, hard starts, drop in fuel economy, injector failure, etc.
AR9100 restores the injectors to OEM performance.
