Another supposedly independent video with great results. 10qt capacity Toyota engine burning 1qt oil every 1500 miles since 120k miles. At 190k miles they started using the Valvoline oil an did two oil changes in10k miles, Stopped burning oil.
I have 3ea 5qt 5x20 Valvoline Protect and Restore on the way for $80 from Amazon (-3 x $5 Valvoline factory digital rebate). Already bought two MANN oil filters so ready for doing the first oil change (myself). I do not have any measurable oil consumption after 111k miles, but at the same costs as BMW spec oil change I am willing to go out of specs (with normal driving) for 2-3 oil changes. Will cut the oil filters open, just for curiosity.
Question:
how long should I use it? In the comments below the video he responds to someone who commented on how clean his oil is now at 2k miles into the third oil change: "We are on the third oil change since switching to this oil. The first two oil changes were black, so it seems the cleaning is done". Which had me a light go off in my head, because all my 5k-7.5k oil changes are black when using the BMW spec oil. So, it seems that BMW spec oils also do a good job at cleaning the engine. May be that's why I am not burning oil yet at 111k miles.
