I needed some fuel for our shop heater at work so I pumped some out of our semi truck and I noticed how dark it was but didn't think much about it. So today I need to top off 2 other diesel cans so I pumped some more from another one of our semi truck and the fuel was normal color. Is their such a thing as blue fuel or is it an additive or what's the purpose? I live in Alaska and we have a fuel truck that comes by every other night to top off our 10 trucks and alot more refer trailers. Thanks guys.
