2001 Dodge Truck no oil added back in after oil change

Did the engine have oil in it when you left the oil change place? Did the engine stall because there was no oil in it? Did the oil light or check engine light ever come on? If so, what was the diagnostic code?

There has been severe damage done to your engine. Let me explain why. We think of oil as a lubricant and that's why we use it inside of our engines, right--WRONG--Water, graphite, even sand are lubricants, so why don't we use them?  Oil is of course a lubricant, but more importantly it has the ability to be forced into small spaces creating pressure, while maintaining it's molucular structure and lubricating abilitys. It also has the ability to carry away dirt and any containiments to the filter, where it is then removed. This is why it is important to change the filter and the oil on a regular basis. When oil is forced into the bearings it creates a wedge because oil cannot be compressed. The crank shaft, rod bearings, and cam bearings life depends on this oil wedge to always be there. When the wedge is taken away, all the bearings loose this wedge. This causes the heart of your engine ( which is the crank, rods, and cam ) to grind up against metal. In your case it grinded so bad that the engine seized up. It's like your heart running without blood, you will have a heart attack, and eventualy die. If a hospital drained your blood then sent you home without putting blood back in and somehow you lived; what would you do? I hope sue the crap out of the hospital. And how do you think your quality of life would be? Would you be the same?  Sorry to be so blunt but I am as upset about this as you are, or should be! The people who drained your oil should pay for this catistrofic mistake. I would demand a new engine to put into my truck. Do not settle for a quick fix or a rebuilding of the engine. A quick fix will get you going for a few hundred miles then you will have problems. In order to rebuild an engine that was seized from a no oil condition, it must be bored out and remachined to bigger than factory dementions. Normaly a rebuilding shop will just measure the tolerances and if they are close enough to get 10000 miles out of that's all they care about. Your engine should be replaced with a factory crate engine period. Settle for nothing less. Keep me posted
BTW who changed your oil?

It started because everything cooled down enough. When metal cools down it contracts. The knocking you hear is all the bearings inside the motor. It was caused by a no oil condition that they caused. I would call a lawyer or at least ask the police to accompany you when you swing by the oil change place. I also would not drive the truck there. They can say then that you are driving it around knowing that this damage is done. I would have it towed and let them start the motor! They are trying everything to get out of this. Call your insurance company and tell them what happened. They may fight the battle for you. DO NOT RUN THIS MOTOR. If they want to hear it, let them turn the key, make them come to you!
