So for those of you that carry an extra 5 gal jug of diesel, but never need to use it. How often do you dump it in the tank just to make sure it's "fresh"?
Off hand, I would think at least every 3 months to be sure it's the right winter/summer mix?
I rotate mine out a couple of times a year. The one I pay attention to is in the fall before it gets to cold. The stations here have already switched to winter blend at this point.
I've yet to actually need it in a pinch, but it's cheap insurance. I also carry extra spare tires for the trailer on longer trips.
