Here I am sharing my more recent experience with MMO and hope it helps some who may experience a similar issue with their vehicle. Vehicle is a 2000 Honda CR-V, AWD and 5-speed manual. I became its owner at 201k miles, it currently has 210k miles. I started adding 4oz of MMO per 10 gallons of fuel on every tank, without adding anything to the oil. Wanted to see if it consumes any. Over the first few fill-ups I had to add 1qt of oil per every full tank of gas driven. That rate increased with longer highway drives, and high RPMs. Also on Higher RPMS (4500-6500) there was a mild visible blue smoke cloud out of the tail pipe. At 206k mies I added a quart of MMO to the oil instead of the now usual top-off at fuel fill-up. Since adding that one botttle of MMO to the crankcase I did not have to add any more oil as it stays at the full mark on the dipstick. Almost 210k as of this morning, still at full mark. And no more smoking out of the tail pipe when I have to rev it up on highway ramps. Driving style did not change, still same ratio of city vs highway driving. Just my experience, take it with a grain of salt. Not claiming it to be a fix-in-the-bottle for any engine problems, but it certainly does have it's place and works well, at least for me.
