I will need to put about another thousand miles to verify and track consumption further, but this is a good sign. I have approached the oil consumption problem, to date, only by taking steps to clean the engine (using PP 5W30 treated with a 10% MMO additive to act as a catalyst to aid this method of safe cleaning), lubricate the upper cylinder (both MMO and TC-W3 have been cycled independently), and adding mos2. The 5W30 is the grade recommended by the OEM, so no thicker oil or use of HDEO has been tried to date, nor an HM oil OC.
I consider the last methods viable approaches, but last resort ones. Going to give the approach I'm taking until Spring to trend consumption usage and give it time to work, before considering the latter methods.
This is still very preliminary, but its a good sign and it would be a nice byproduct of the chosen additives. Note that peak consumption since buying the car in May has been significant, at one quart over a 1,200 mile interval; but not past what I considered the point of no return, where consumption is so high that no approach will likely yield any results. High enough to be close to that point though, so I have been prepared all along for worse case scenario where my efforts lead only to halting further increases in consumption, but do little to reverse the process.
Edit: I should add that the very first step taken, before beginning the approach taken, was mechanical: my engine had sludged, and this may have had a negative effect on consumption, due to a gummed PCV valve that I replaced. Replacing the valve in and of itself did not reduce consumption, but that was a first and necessary step taken before the use of additives. Where possible, IMHO, its always better to address the cause than treat the symptoms or try and mask the problem.

My car runs smoother with Mos2. I need no other testing. This ocmpany is very higly rated by car guys everywhere.

Based on my experiece, I may try some of their other products. As needed of course
