i saw in diesel power magazine an add for something called the Premier fuel cell. It claims to give you a minimum of 10% better fuel economy by helping the fuel to burn more complete. I have a diesel truck and no so hot fuel mileage. With the price of this low sulfur crap i am having trouble affoding it. would this thing work?

 

I'm not too sure it will provide a 10% increase though I do believe it will provide some benefits.

 

It sounds like a bunch of bologna to me. I'd stay away from it. Use synth oil or xmn fluids in all your gearboxes. Keep you tire pressure correct. Use better air filters.
