I have a 08 dodge charget R/T. It Now have 184k miles on it. I did a oil change back in March of this year when it was at 174kmiles. I used amsoil 5-20 signture series with there 25kmiles filter. Last week ive been noticing some jurking and somewhat small skipping around 65-80mph. Not nothing noticable, just something that I could tell. Just out of curiousity I checked the oil. Coulnt get a oil reading. So I checked and checked numorous of times, still nothing. I cranked the car and then checked it again, the dip stick gave me a reading of full. I thought nothing of it, because amsoil is suppose to be one of the best oils money can buy, im thinking that there no way that this oil could of burned that much within 10kmiles. I begin to think that there was problem with the dip stick. I even checked for leaks, no leaks. I continued to drive it, I then started to notice some knocking and clicking noise. I shut the car of and checked the dip stick, nothing. Crank the car up and checked again. it still read full when running. I grab a 5 quart containter of Mobile 1 that I had in my garage and added one quart while the car was off, checked the dip stick and I could see a reading on the dip stick. I added 4 more quarts and now the dipstick reads just a quart below the full level. How could this be? Why did I lose so much Oil within 10kmiles? What should I do? Thought about calling amsoil and getting a refund. SHould i change oil and filter even though I added new oil? Thought about trying out that new Pennzoil Ultra Platinum with a Fram Filter. Could someone please help!
