Don't waste any money on fuel. Best have a professional technician listen to your engine to determine how serious of problem you might have.

have a diag done by a mech and don't drive until then you can cause more damage

Most probability crank shaft damage due to lack of lubrication, May be a good time to decide to fix or replace Engine or vehicle . It will be a significant expense. Before you make that decision , have a shop check for loose bolts to the flywheel. Some times it sounds like a bad rod .
i juss got a 99 expedition 4 free wit 280000 i was driving it and started knocking wen i look it had no oil ...how much is it to fix it or how much is it to put a new engine... and is it too hard ...
Hear this all the time has me very concerned.
I noticed I hear a knock when the truck is at operating temp.. Knock is noticable when the truck is in gear stopped 117000 miles.
my engine makes a loud knocking noise when in park and when I shift to drive it stops but when driving my 4x4 sensor light flashes when driving and my radio goes in and out
