Using that much oil has clogged it again. Inframe doesn't change anything but get you back to normal consumption level.

I had the DPF filter cleaned at 270,000 miles
At 310,000 it began using oil. Approx 1 gal per 1300-1500 miles
Cummins replaced the head - it still used oil.
At 322,000 I had in-frame, DPF Filter re-cleaned and Dozier valves cleaned - so they said.

1.5 weeks later engine light on again, this time it shut me down in FLagstaff. Actuator was bad, and Trubo, and they replaced Dozier Valve.

Next day engine light on again



But since the in-frame I've only ran 20,000 miles and added 1 gallon of oil. My new interval to change oil will be 20,000 miles max. Next Speedco I pass I will change it.
