I see some familiar people here, hello! I'm a fairly long time MMO user, a tradition passed down from decades of dad using it. I recently tried TC-W3 and for some reason like the MMO better in the gas. The engine seems to run well with either, but I have given up slight mpgs with the TC-W3. I also noticed that if you give too big a dose of TC-W3 the engine lacks some power, where as you would have to go hog wild with the MMO. Just my observations, YMMV.
Interesting observations. I'm a bit over a month into my syn TC-W3 experiment, so far using only the Penz ester-based full-syn version. My engine seems to love the stuff. I can feel it "seat of the pants" and I'm seeing a slight, but pleasing increase in mpgs (guessing it will stabilize at around 2 mpg, maybe very slightly less).
Regarding your comments about the TC-W3 -- remember that unlike MMO (and I have no problem with that product), TC-W3 oils have to meet prescribed industry standards. But more importantly, they MUST function as complete lubrication for the 2C engines for which they're really meant. Since this stuff has to carry a full burden as engine lube, I'd expect it to be a more "stout" oil, and one that if overdosed into a 4C engine, might very predictably cause things to bog down some. At the proper dose, however, I'm starting to believe that TC-W3 is the near-perfect answer to the hot, dry, barely lubricated top end of a modern 4C car engine.
