The Motor Oil Geek posted a video this week saying he thinks fuel additives do protect against piston wear, and are just as important as quality oil. It's lengthy and technical but that's his conclusion. I always add a bottle of Regane plus a dose of UCL with every tank. Definitely happy to see an industry professional like Motor Oil Geek come out supporting extra additives.
Please search diligently before starting yet another thread, especially on LSJr videos ...
Further, PCMO is not a place to discuss fuel and wear; that would be the "fuels and fuel additives" part of our site.
