Diesel Fuel

jeebuz, I cant believe the "facts" that some are pulling out of their hats here.

Just stop, seriously, I have never seen the internet provide so much bad advice as I have in this thread.

even if the odds are 50/50, a few minutes to fill a fuel tank and add 15 dollars worth of additives could save the OP thousands of dollars.

This is what I would do (or actually do). I rarely drive my truck from November - March. I fill the tank, add winter fuel treatment so it does not gel should I need to drive it, and let it sleep in the garage until it is time to use again.

Totally agree. If something is going to grow in the tank, it did come from an external source.

But, not that hard to imagine that at least ONE station you fueled up over the last year or two DID have a contamination issue.

Algae in todays diesel fuel is extremely rare. If you are fueling from pumps that have no filtration, in my humble opinion you probably deserve what you get.

The black yuckey stuff we see in fuel filters is often mistaken as algae but in reality is tar. caused by fuel separation from long term storage.

But as mentioned by the OP his fuel isn't going to be stored that long.

I run diesel fuel that suppose was 7 years old, while 4 years diesel in my tractor never was a problem.
Living in dry climate I never found a drop of water in the fuel, but don't know how it works in different weather.
In last years all states add 7-20% of biodiesel, that is having cleaning characteristics.
No clue if that helps in long storage, but other effect is that bio can be less steady fuel than diesel.

I'd fill the tank.

Are you planning on running the generator while you're stationary? Does is run off the diesel tank?

I consider a biocide as "Preventive Medicine". Really no big deal. With the Biobor JF we use, less than 1.5 ounces per 100 gallons.

But your coach, your decision.

Also agree with MudChucker. If storing summer grade fuel (#2 diesel) into below freezing temperatures, add an anti-gel.

So much misinformation here.

If you must do some thing, this is the easiest and most productive.
