In reply to Craig. There are fuel test kits that are able to be found online. If the fuel has been stored for a couple years it is most likely bad by now though. It may still work but it will definitely be sub-optimal.

My dad had a diesel truck several years ago I have recently bought one in the last eight months and he my father brought me over 3, 5 gallon fuel cans for diesel he said he found in the shed so I don’t know how long it’s been stored in the cans but like I said it’s been a couple years since he owned a diesel should I put it in my truck or not is my question and if I pour into a clear gallon jar will I be able to see if there’s any problems like water or jellying? How could I know for sure whether it’s safe to run in my 7.3 powerstroke? And what if I only put a gallon into each full tank do use it up

My dad has been telling me how bad he needs a fuel refill for his tank, that’s why we’re currently looking for a service that may provide that. I never knew that a diesel fuel additives are needed, or else the diesel will go bad in 30 days. I’m glad you shared this; we’ll also make sure to keep the tank full, so water issues could be minimized.

In reply to easop. Odd comment. I stumbled on this web page and have found it very useful. I noticed Sta-Bil mentioned several times and highlighted with a link. So I figured there probably was some connection between goldeagle.com and Sta-Bil. For you easop, think of your favorite fuel preservation treatment and whenever Sta-Bil is mentioned, think about that other product. You've read a long way through this thread to determine there was no good info here for you. Full disclosure: I have a small bottle of Sta-Bil I bought about 10 years ago. Luckily it has Sta-Bil in it so it won't go bad.

When it comes to keeping diesel for a long time in storage it’s good to know that there is a potential chance of the entire payload going bad if it isn’t preserved for extended periods of time. When the need to store diesel fuel is undeniable it’s best to keep the thing stored in a clean, cool, and dry place. If I had the need to store fuel for that long a period of time I would have to find a place to keep it without deteriorating.

In reply to John Haskell. Hi, John. Typically, diesel fuel can last (under best conditions and quality of fuel) from 6-12 months. After that, it starts to oxidize, lose volatility, cetane, becomes stale, can develop microbial contamination and ultimately become solid (sludge). This can cause engine performance issues, jam fuel system parts (injectors, lines, filters etc.) and even cause overheating. If it has been that long, the best thing we could recommend is to drain and start fresh. At the very least you can have it tested.

Your advice about minimizing the water issue with diesel by keeping your tank full is really beneficial. Diesel fuel is super useful, and it may be a great idea to have it delivered to your location in order to avoid unnecessary trips. If I were to need such services, I would contact a fuel delivery company that works in a timely manner. http://www.fuelmanhawaii.net/services

I have had Diesel in storage for 20 years for an Emergency Generator. When needed the generator is not performing as it did but still gets the job done. Am I to worry since after this long it may have settled to where it’s going to be. The fuel truck added 1/2 gallon of stabilizer when filled but nothing has been done since then. I have the tank higher on one end for water issues & the pick up at the high end. Probably 750 gallons left. What would you suggest, changing the fuel or testing, replacing or leave it alone. (The vendor claimed then, it was good for 10 years. They are out of business).

In reply to Nicolas B.. Hi, Nicolas. In this particular situation, perhaps it would be helpful seeking a second opinion from a different professional technician.
