As neglected as that Bentley-wanna-be-pos-mobile in the video was, it barely saw oil, and I mean, *any* oil.
Look
@TiGeo, obviously I don't know much about Liqui Moly or the Lubetech stuff, so I won't pretend that I do. I just don't use additives as a general principle. If it does something for your vehicles, than that's great. Somehow I doubt that this stuff can do anything for a WWII-era basic low-tech push rod engine design. Fifty years ago engine lubricants weren't what they are today, yet those engines somehow survived and performed. Now, all of a sudden, special lubes and additives are needed for them. Logically, this is indicative of a quality control issue that no goop, no matter how fancy, can fix. Maybe it's something that doesn't happen that often, and maybe it was already addressed during manufacturing. So there is no point in using something that might do more harm than good just out of fear.
