5 Common Diesel Storage Tank Problems (and How to Prevent Them)

Your diesel storage tank might look solid from the outside — but internally, many tanks are silent threats to your generator and business continuity.

At Wizcoasts Oil, we’ve worked with dozens of clients who came to us only after their equipment suffered damage from dirty or improperly stored diesel.

Let’s help you avoid that mistake with this guide.

⚠️ 1. Water Accumulation in Tanks

Tanks exposed to heat and rain often collect condensation inside. This water settles below the diesel and enters your system — leading to engine misfires and corrosion.

Solution:
Schedule regular tank sterilization and water detection tests. We use litmus paste and density tests to catch contamination before it spreads.

⚠️ 2. Sludge & Sediment Build-Up

Poorly maintained tanks lead to the build-up of sludge at the bottom — a mix of old diesel, water, rust, and microbial growth.

Solution:
Have your tank cleaned and sterilized every 3–6 months depending on usage. Our cleaning service ensures the tank interior is safe for long-term storage.

⚠️ 3. Tank Leakage or Cracks

Tiny cracks often go unnoticed until diesel begins to disappear. Besides environmental hazards, this can result in major financial loss and fire risk.

Solution:
Wizcoasts offers tank inspections and pressure testing to detect and seal leaks early.

⚠️ 4. Rust Contamination

When moisture enters your tank, it reacts with the metal and begins forming rust. That rust eventually contaminates the diesel and clogs injectors.

Solution:
If you store diesel for long periods, ensure your tank is stainless steel or properly coated — and request internal cleaning often.

⚠️ 5. Improper Tank Type for Your Location

Some businesses use tanks that aren’t rated for external or underground use — leading to collapse, burst lines, or temperature instability.

Solution:
Let a certified professional (like Wizcoasts Oil) recommend the best tank size, placement, and material based on your environment and usage.

✅ In Summary:

Your diesel is only as clean as the tank that holds it.
By investing in regular tank cleaning, sterilization, and monitoring, you protect your engines, reduce maintenance costs, and increase diesel efficiency.
