Losing 1gallon of oil per day

Recently my 97 7.3 had started using 1gallon of oil per day. It's not coming through the turbo andno visible leaks on the frame or ground. Fuel economy went up about 6-7 mpg at the same time so believe it's going back to my fuel tank.

I replaced all the injectors with rebuilt ones in October. I called company to get their opinion and the guy suggested it was probably either a clipped o ring on install or bad ipr sending to much.

Any thoughts on if these are more or less likely would be appreciated. Thanks

Take a look at your fuel filter, I am willing to bet that it is black.

I am almost will to bet on a bad injector O ring.
