Is winter fuel retreatment necessary?

[schmitts]

At the end of last season I topped off the tank in my Journey 40L and added Biobor JF. We didn't take the rig out this year, and it will be stored in Michigan over the Winter. Should I add another dose of the Biobor or should the tank be good?

Hi schmitts,
I believe it should be good without adding more, providing the bottle with which you treated the tank is less than two years old at this time. The rated shelf life for Biobor-JF is three years:

Because this is a long time to not use a tank of diesel, I would be ready to replace your filter(s) when you run it next spring.

Thanks for your advice, E5!

I tend to look at things from the risk/reward angle.
How much trouble/expense to add more and be sure versus what it costs me if I cut things to short and have to deal with the results of a mistake?

I remember it getting pretty cold most every winter in Michigan? Does it still do that?
I never wanted to take chances when I was up North!

I took a coat with me, even if I was going to be in the car!

Thanks for your reply, Morich. Not trying to save money, I have the Biobar. I'm just hesitant to add the Biobar when I'm not going to drive the rig to get it mixed through the tank of diesel. Also my understanding is that getting water and perhaps algae in the tank isn't a common problem in Michigan because it is so cold, so I suppose that's working in my favor.

Yes, see the question better if not going to drive a bit. Those small points can often make the difference, Sorry about what I assumed!
If not driven, it may just mean more than needed in the tank and none getting into the lines and all those little spots where we find it really needed most??
Any possibility of adding it and then even just running the Rv a short distance back and forth to mix it and then let the engine run for a bit to get it in the lines?

Hope you knew I was joking when asking if it still gets cold there. I spent some time in WAY cold country and it still effects my thinking 50 years later.
We had tunnels to use to go to eat because it was too cold to go outside!
Actually it may have cracked a few spots in my brain!

Yeah, to some extent I'm just being lazy. I suppose driving a bit around the park would do the trick. I just don't want to have to bring up the jacks and get it back in place if there isn't a real benefit. And taking it on the road means paying for a month of a license. That's why I liked Eagle5's reply. But your advice makes sense, too.

Michigan winters have actually gotten pretty mild. I'm near Detroit and last Winter I only used my snowblower once!

I agree.

I'm with Richard. You really can't overdose the Biobor.

I would run the rig up to operating temperature to circulate the fuel in the lines and tank, it also helps remove any moisture in the engine!

Cummins says 20 minutes minimum after reaching normal temperature is required to evaporate moisture in the crankcase; that's driving time not idling time.
