Low on oil

I have a 2002 f350 w/ 7.3. The truck has been a beast and in 100,000+ miles has had literally no problems... which is quite remarkable given my aging fathers level of maintenance!

I jumped in 2 days ago and started it up normally and went two country blocks before it shut off and died completely. I towed home to assess and found low oil (not even registering on dipstick) so I changed all filters, oil etc. The oil pan had a great deal of oil still over 2 gallons) I cranked and was able to started it up but definitely a hard start. It is running rough with very little power. I am considering that low oil pressure (d/t the low engine oil levels) may have damaged or fouled an injector? What else can I check. What are your first thoughts on this scenario? Thanks ahead guys.

First thoughts. Low oil level leads to aeration of the oil. Since the injectors are oil driven, aerated oil will not allow them to work properly.

2 gallons of oil in the pan is only half full. There is a reason these trucks take so much oil. It is literally the lifeblood of a 7.3.

Drive it a bit. Its going to take some miles to work the air out of the HPO system.

Spot on. Thanks! Runs great. Still a bit longer start, but maybe that will work itself out too.
