I got my 2000 Honda CR-V, (AWD and 5-speed manual), at 201k miles. Put Pennzoil SRT 0w40 as first oil change, and between 201k and 206k I ended up adding another 17 quarts of oil, due to oil consumption. Then added 1qt of Marvel Mystery Oil, and did not have to add any oil since then. 212Kmiles now, oil stays at the level that I fill it up to throughout the full oil change interval. Worth a shot at less than $4 per quart from Wal-Mart. And if it does not help - your engine is at least a little cleaner inside. But I guess since you took a pass on that Acura - this trick can wait for another oil burner.
