Checked against the Marketing Discipline Guidelines 2024 (Ver. 1, effective 24.10.2024) on 15 October 2026. Published by MDG Services on 28 October 2026.
What goes in the register
As laid out, one form covers one tank of one product for one month MDG Annexure 1. The entries, by the moment they are made:
| Moment | What goes in | Clause |
|---|---|---|
| Every morning | The opening density at 15°C from a pump nozzle sample, against that day's date. Before the first sale, by 10 AM | MDG 1.4.1(c) MDG 5.1.9 |
| A tanker arrives | The reading of each compartment's sample, and the 15°C density printed on the invoice. Before decanting | MDG 1.2(viii) MDG 1.1(v) MDG 2.2.1(iv) |
| The load has gone into the tank | The 15°C density of the mixed product, from a nozzle sample drawn after at least 50 litres went through the pump | MDG 1.2(xiv) |
What MDG leaves open
Ask your oil company about these two points:
- Temperature on the compartment readings. MDG says each compartment's density and temperature are recorded MDG 1.2(viii). The form states the invoice and after-decanting entries at 15°C, not the compartment entry MDG Annexure 1. The ±3.0 check is made on the 15°C figure MDG 1.2(iv).
- Several compartments or several loads in a month. The form does not say how its entries are meant to be used then MDG Annexure 1.
An example
An illustration with a made-up outlet and figures: Tank No. 2, petrol (MS), kg/m³ at 15°C.
| Day | What was recorded | Figures |
|---|---|---|
| 1 | Morning reading | 743.5 |
| 2 | Morning reading | 743.5 |
| 3 | Morning reading, then a tanker | Morning 743.0. Compartments 744.5 and 745.0 against an invoice density of 743.0. After decanting and 50 litres through the pump: 744.0 |
| 4 | Morning reading | 744.0 |
On day 3 the compartments read 1.5 and 2.0 above the invoice figure, both within ±3.0 kg/m³ MDG 1.2(iv). Which of these figures an inspector asks for depends on the time of the visit: see the reference density rule.
Corrections and other records
MDG has no correction rule for the dealer's register. The only one covers the mobile lab's Record Book and test reports: strike through the old value and write the new one beside it, with name, designation and signature MDG 7.6.2. General practice, not an MDG rule: do the same, and never overwrite.
For the other records MDG lists, and the amounts for missing ones, see the records to keep.
Questions dealers ask
01What is the petrol pump density register format?
Annexure 1: a form headed by a tank number, a product and a month. It holds the date, the morning reading, each tanker compartment's reading, the invoice density at 15°C and the 15°C density after decanting MDG 1.2(xiv) MDG Annexure 1.
02How long must the density register be kept?
For the present financial year and the one before it MDG 5.1.12. The usual Indian financial year runs from April to March; MDG does not define it.
03What happens if the density register is not available at an inspection?
It is an irregularity: major if the records since the last inspection are missing, minor if only older ones are MDG 5.1.12 MDG 8.3 MDG 8.4. A missing morning or after-decanting figure also counts as missing reference density MDG 5.1.9.
04Does the oil company supply the density register?
MDG says the company provides the daily stock register MDG 1.3(ii), but for the density register it names only the format MDG 1.2(xiv). Ask your oil company.
