Oil Consumption and poor MPG and power
99.5 crew cab 4x4 long bed. Stock turbo, and injectors except for #8 was replaced a year ago. 4" exhaust from the turbo, tymar intake. Twice in the last 6 months the truck has died going down the road. Both times the stick didn't show any oil. The last time, I added 2 gallons of oil after 3,000 miles since the last oil change. Rotella 15w40, and it was full. Drained some fuel this morning, it was clear, no oil in it. Valley is not full of oil, there is a very little bit in one of the voids. No oil leaks under the truck. Exhaust is just dry soot, no oily mess. The compressor wheel is dry and does not have any play. Pulled the intercooler hose off of the left side of the turbo, it was dry, no oil at all.
Also, my power just does not seem to be there anymore. I do run a DP tuner at the 80 hp econ, and the 60hp tow when I pull my 5th wheel. Camper is 10k unloaded. Used to pull it with no problem, no she has a hard time staying at 65mph. Florida driving, no hills, no winter blend fuel. Also, my mileage has gone down, I used to get around 16 mpg, not I'm lucky to get 13.
Thanks for any help you can provide, and sorry for the long writing.
