I've 2 gallons of diesel in a proper plastic container that I bought before a holiday 5 years or so ago. Never used it and I'd like to get rid of it. Any reason why I shouldn't use it in the car? Does diesel go 'off' in any way over time. I'd fill in via a funnel with a strainer in it.
Just seems the easier way to dispose of it. And before anyone suggests it, I don't have any sheds or fences that need weatherproofing!
