i bought some amsoil diesel concentrate, and was just wondering since its a redish color..would it stain my tank at all? I've had it a while just dont want to add it and have it stain my tank all up. Thanks.

 

No it won't stain. I thought it looked more brown...never really looked that close. Once in the tank, it dilutes so much, you can't tell it's in there by color. I've changed fuel filters and the fuel in there didn't look any different.

 

ok good thats nice to know, just wanted to make sure before i start adding stuff in my fuel. Thanks!
