Liqui MolyLIQUI MOLY Super Diesel Additive | 300 ml | Diesel additive | SKU: 2002

How does this stuff compare to diesel kleen +cetane boost by power service? better or worse?

Is it normal to see foam in the gas tank after adding this? I poured it in my tank then added fuel. When I removed the nozzle there was lots of foam.

How many gallons does it treat per can????

can this be used in a 2000 7.3 powerstroke
