JeepCares, this is all good "guideline" info., and keep up the good work posting this type info. IMO, excessive oil consumption, in many cases (in addition to your service bulletin) can be traced back to the initial break-in of the engine. If it's driven like "granny" during the break-in period, you're more likely to have an increase in oil consumption later on. Today's engine assembly tolerances are much tighter than in the "old days", but a good varied RPM break-in will still, in most cases, result in less oil consumption over the long run. I bought my Hemi Magnum new and broke it in as indicated above and it doesn't burn a drop between 6000 mile changes. I don't know how my Hemi WK was broken in, but it uses a little (maybe 1/2 qt) between 6000 mile changes.I do get some through the PCV Valves and into the catch cans in both though, but it is minimal. I'll be doing an experiment soon, by adding a second in-line PCV valve to see if it will, (1) work properly and (2) reduce valve oil bypass. This will be an effort to correct the lousy stock PCV system in the Hemi's.
