If you have to hit the fuel with a biocide, be very ready to replace both fuel filters and learn how to bleed a dry fuel system.

Well, I guess I'll have to be prepared to pay someone to do the work that needs to be done. Obviously I'm a novice with diesel engines.

Diesel fuel isn't like gasoline.
No worries with gasoline. Just don't expect max performance until you burn it up and refill.

Actually, your NOSE is a very good guide to the state of the fuel.

If it still smells like diesel, you are good to go.

If it has "turned" have it drained-- someone may be able to use in an oil-based furnace. If turned, certainly not worth doing damage to an expensive injection system.

Tell us what your nose says.

Hard to know what to do when others are sayin 'just drive it'!

As it has been said, if it smells ok, just top it off and then drive it off, or at least as much as you can.

I would highly advise having spare filters.

I live in Florida with our heat and humidity. I left my diesel pickup sit for a bit over 2 years. When I went to start it, no problem. I drove it to the nearest station, topped off the tank and I was good to go. Never had any issues.
Now if you are still concerned, one option is to get a fuel polisher to come over and clear your fuel. Since you are in Michigan, there will probably be some fuel polishing companies on the lake that can come over and take care of it.
Here are some in Michigan from Google. Good Luck

I'm not sure I could tell you what good diesel smells like. Maybe I'll have someone more knowledgeable take a sniff. But you think I should get some fresh diesel in it right away?

Hey, thank you, Joe, that's a really helpful post. I'm going to look into this.

Yes, fuel polishing (common on diesel boats because of the same storage issue) is an alternative.

That will remove water, microbes, dirt etc.

It will not "cure" diesel that has "turned". Smell fresh diesel, then smell from your fuel fill. We are not talking about a subtle difference!

Yes, we FEEL you will be fine. But would sure hate for our long-distance opinion to lead you into an expensive repair.

Haven't found anyone locally who does this. I'm in St. Clair, MI. I have a Love's across the street from my campground and they don't do it, nor did they know anyone who does.
