The average lifespan of diesel in a portable fuel tank is around 3-6 months, although this can vary depending on various . One of the most significant affecting the lifespan of diesel in a portable fuel tank is temperature. Diesel fuel is more stable at lower temperatures, so storing it in a cool, dry place can help extend its lifespan. How Long Does Diesel Fuel Last in Storage? As per BP data diesel fuel can be expected to stay in a useable condition for: 12 months or longer at an ambient of around 20ºC. Heating oil includes several grades of petroleum fuel oils: No. 1, No. 2, No. 4-light, No. 4-heavy, No. 5-light, No. 5-heavy, No. 6, Navy Special Fuel Oil, and Bunker C. No.2 diesel fuel and kerosene are not defined as heating oil, but are considered a substitute for heating oil when used for heating purposes only. Determining the storage life of diesel can be tricky, as it depends on various factors, such as the container, environmental conditions, and fuel quality. Under ideal conditions, with high-quality fuel and appropriate additives, diesel can be stored for up to 1-2 years. In average conditions, with moderate temperature fluctuations and fuel Both tanks were produced using a fire retardant resin system although we feel the base resins for each tank are of a different type. Both tanks have absorbed in the range of 4.2% fuel into their volume over time (tank bottoms). The top of the newer tank has also absorbed over 4% fuel. The top of the older tank has absorbed 2.2% fuel over time. The lifespan of each tank may vary slightly, however the anticipated lifespan for steel fuel tanks is between 20-30 years. As a tank ages past 30 years, it becomes only a question of time before that tank will begin to leak. In fact, it is not a matter of if the tank will leak, but simply a matter of when, as all steel tanks placed underground AIbQm. Heating oil includes several grades of petroleum fuel oils: No. 1, No. 2, No. 4-light, No. 4-heavy, No. 5-light, No. 5-heavy, No. 6, Navy Special Fuel Oil, and Bunker C. No.2 diesel fuel and kerosene are not defined as heating oil, but are considered a substitute for heating oil when used for heating purposes only. 12+ months: If the temperature is kept below 70 degrees F There are many anecdotal reports of diesel fuel lasting much longer than this. I’ve read in forums of diesel fuel lasting 10+ years and being okay. However, you’ll risk ruining your machines if you use expired diesel. What makes diesel go bad? brought to you by your friendly refiner (BP): LONG TERM STORAGE OF DIESEL Issued : February 7, 2002 ADF1402 Supersedes : February 14, 2000 Page 1 of 3 BP Australia Limited A.C.N. 004 085 616 Marketing Technical Services STORAGE LIFE Under normal storage conditions diesel fuel can be expected to stay in a usable condition for: • 12 months or longer at an ambient of 20ºC. • 6-12 months at The first five digits of the number indicate YYDDD, with YY indicating the last two digits of the year of production and DDD representing the number of the day of that year of production. For example, a production code of 12272 -73995-10:30 indicates the bottle was produced on September 28, 2012. September 28th was the 272nd day in the year 2012. Use Diesel Formula STA-BIL® whenever you put your diesel fuel engine or diesel equipment in storage, specifically 1 ounce for every 5 gallons of fuel. This will keep the fuel fresh for up to 1 year. If you need it to go for longer than the year, you can add a double or even a triple dosage, two add two to three years respectively.
