Can diesel be stored in a new gas can?

Answer 1

You bet. Gas cans can hold any fluid.

Let's talk about the difference between gasoline and diesel. Diesel has a lower viscosity rating than gasoline, thus a higher flash point, because it's thicker and more difficult to ignite than gasoline.

Simply put, it's more oily than gasoline. Pour diesel on a log fire and strike a match to it, it ignites slowly and is easier to control. Pour gasoline on a pile of logs and strike a match to it, and after the bright light and loud wooof, you find youself without eyebrows and forearm hair. Store diesel in gas cans? Sure. But make sure and label it as diesel so you don't mistakenly think that it's gasoline and put it four cycle engines like a lawn mower or in your car. Regardless, treat it with the respect it deserves.
