I added seafoam to gas in my motorcycle 2 weeks back. I then bought B12 7516. My tank is almost empty now. Can I add B12 7516 during my fill up? Is it ok if B12 mixes with seafoam?
The two products are chemically compatible, but SeaFoam has an base oil component that doesn’t burn especially cleanly and can build up in the combustion chambers over time. 7516 will help combat any such deposits, so the less SeaFoam you have in the tank, the better performance you’ll get from 7516.
