I've done 3 treatments in my truck so far for oil burning. ARX managed to cut down on the amount of blue smoke, but could not stop it - reason being its a mechanical issue, my valve guides are shot. ARX cannot fix a mechanical problem that's already there.
That said, the improved fuel economy and performance alone were worth the treatments and I'm going to be running half a bottle once I sort out the problem in June. The new seals and gaskets would have a great start to their service life that way.
