On August 25th, I had a routine oil change on my daily. Always at or near 3500, never over 4k. Mostly right before 3500. They had someone new do my oil change. Side note, I have 2 car and I also know everyone there and they know the look of my cars. The service writer rudie had his son working there, he was the one under the car doing my oil change. He didn't screw down the oil filter all the way down after filling the system with oil. The Saturday before the oil light clicked on. I was under the car with my uncle(the mechanic of the family) He noticed what looked like gear oil.(motor oil and gear oil has two different smells. So he said.) Didn't notice the leak in the oil filter at the time. But it was leaking out of the top of the filter at the base where you screw it into. And it was dripping on my front differential. Monday night my oil light popped on and off twice. I went home and after a few moments in park at idle. I heard it. knock knock. Cut the car off and restarted it. Still a soft knock. Popped the hood. Checked the dipstick, she was completely dry.( I have paper work stating the repairs I've done to this car. Completely rebuilt the front end from top to bottom. Minus the front differential and transfer case. Everything else has been replaced. I got under neither and then finally discovered the leak from the oil filter. Also I was able to twist it tighter to the right almost 1/4 of a circle. That night I put 4 quarts of oil in the system. Next day went to take 5, I was told the gm wasn't there to call corporate. Still the assistant manager also said there was a knock. He noticed it leaking and tightened it with there special clamp tool. So I decided to put a fresh oil change in the nitro. I'm religious when using certain oils. My nitro has always taken 10w-40 high mileage Castrol GTX. 5 quart system. This time, I used Lucas oil stablizer treatment. To try and quiet it down some. Went back to take five. Was talked to my the father of the son that did my oil changed. He was very concerned because I'm up there often. At least twice a month for my daily. After the oil change. I was told to hit the gas until 3000 rpm. Soon as I did I heard the ringing. Like a school bell. Or a fire alarm. High pitched ringing. The oil was at a safe level. But the damage was done due to not screwing on the oil filter all the way. I left and it wasn't 6 hours later. The engine was knocking so loud I had to pull off the interstate and get a tow home. Now they are jerking me around and my life is going down the drain because my daily can't move due to negligent service. It's been 3 weeks since the 25th. About 1 week since the gm and district manager came and talked to me about it. Also looked at the car. If you have kept reading this far. Thank you for your patience. But beware of these young kids they higher
