Hi Norm and Tyler
Yes I've also had mowers people filled with Diesel. Yep the lighting of a small amount as Tyler suggested is a good test.
I can tell from the smell , the easiest way to tell is to put a small amount on the ground and try and light
the fuel with a match.
As we know.
If you toss a lit match into a puddle of diesel fuel, it’ll go out.
You aren't supposed to light fuel at Home for safety reasons but if you're careful to light a very small amount then it should be safe.
Diesel is much less flammable than gasoline. In a car, it takes intense pressure or sustained flame to ignite diesel. On the other hand, if you toss a match into a pool of gasoline, it won’t even touch the surface — it ignites the vapors above the surface. (Please don’t do this at home!)
Cheers
Max.
