The Hidden Cost of Short-Filled Gas Cylinders — And How to Protect Yourself

Ask any household in Lagos, Abuja, or Port Harcourt about their worst experience with a gas vendor and the story is usually the same: you ordered a full 12.5 kg refill, paid for a full 12.5 kg, and finished your gas in two weeks instead of the usual month. Short-filling is one of the most pervasive frauds in Nigeria’s informal LPG supply chain.

How short-filling works

A standard 12.5 kg LPG cylinder has an empty weight (tare weight) stamped on the collar — typically between 7.5 and 9 kg depending on the cylinder’s age and manufacturer. When full, the cylinder plus contents should weigh tare weight + 12.5 kg.

Short-filling works by filling the cylinder to less than its rated capacity — say, 10 or 11 kg — and charging for 12.5 kg. Without a scale, there is no way to know. The weight difference is not visible, not detectable by shaking, and not obvious from the pressure of the gas coming out.

If you are short-filled by 1.5 kg on every 12.5 kg refill, you are paying approximately 12% more per kilogram than the listed price — and you have no way to prove it without a scale at the point of filling or delivery.

The financial cost

At a selling price of ₦1,500 per kg, a 12.5 kg refill costs ₦18,750. If you receive only 11 kg, the implied per-kilogram price you actually paid is ₦1,704 — a 13.6% premium you did not agree to and cannot see without a scale.

A household that refills monthly and is consistently short-filled by 1.5 kg is losing approximately ₦27,000 per year. Over five years, that is ₦135,000 — enough to buy two cylinder sets outright.

Why it is so hard to prove

Three factors make short-filling almost impossible to challenge without a scale:

• You pay before you can check. Most vendors collect payment on ordering, not on delivery. By the time you notice the gas running out early, the transaction is long closed.
• No receipt, no reference. Most informal gas deliveries in Nigeria produce no written record. You have no documented claim to a specific quantity.
• Plausible alternative explanations. Vendors can always claim your appliance has a leak, your usage changed, or the cylinder is old and naturally depletes faster. Without an initial weight reading, there is nothing to argue against.

How digital weighing at delivery eliminates the problem

The solution is simple but requires the vendor to agree to it: weigh the full cylinder at the point of delivery, in front of the customer, before payment is confirmed.

This is precisely what Sureflame does. Our delivery technician carries a 150 kg Camry industrial scale — the same type used in commercial produce markets — on every delivery. The cylinder is placed on the scale at your doorstep. You read the display. The combined weight (cylinder + gas) is checked against the expected total (tare weight + 12.5 kg or whatever size you ordered). If it does not match, the delivery does not proceed.

Every transaction is also recorded digitally with a timestamp, location, quantity confirmed, and payment reference. There is a complete audit trail for every kilogram we have ever delivered.

What to look for in any gas vendor you use

If you are not using Sureflame, here is how to protect yourself from short-filling regardless of which vendor you use:

1. Ask for the cylinder to be weighed at delivery. Any reputable vendor should accommodate this. Refusal is a red flag.
2. Know your cylinder’s tare weight. It is stamped on the collar. Write it down. Full 12.5 kg + tare = what the scale should show.
3. Pay on delivery, not in advance. Advance payment removes your only leverage.
4. Keep records. Note the date, quantity, and price each time. Patterns of early depletion are your evidence.
