What MDG 2024 lists for petrol
MDG's petrol table covers the BS VI grades MG, E5, E10, E12, E15 and E20 MDG 7.6. Its two columns give the same density. The lines for MG 91, MG 95 and MG 98 are about colour MDG 7.6 and octane MDG Annexure 5, not density. The petrol mobile lab report also carries a single 720–775 MDG Annexure 12a.
| Line in MDG's petrol tables | MG, E5, E10, E12, E15 | E20 |
|---|---|---|
| Density at 15°C, kg/m³ MDG 7.6 | 720–775 | 720–775 |
| Minimum octane number (RON), by grade MDG Annexure 5 | MG 91: 91, MG 95: 95 | MG 95: 95, MG 98: 98 |
MDG never uses the word "premium" and does not say which grade is which brand.
Power, XP95 and Speed
MDG names none of them MDG 7.6. General knowledge, not MDG text: oil companies sell their premium petrol under brand names such as these. Octane describes how well petrol resists knocking in an engine. It is a different test from density. Which MDG grade a brand matches, ask your oil company.
A pump that sells both
Each lot is checked against its own invoice, whichever petrol it is:
- Note the 15°C density the supply location wrote on the invoice MDG 2.2.1(iv).
- Read density and temperature on each compartment's sample, convert to 15°C and compare. The gap must be within ±3.0 kg/m³ MDG 1.2(iv) MDG 1.2(viii). See the invoice check and the 15°C calculator.
- After decanting, the reference for that tank is its own mixed reading, taken after at least 50 litres have run through the pump MDG 1.2(xiv) MDG 2.10.
For example (made-up figures): one lot is invoiced at 746.0 and reads 747.5 after conversion, a gap of +1.5, inside the limit. Against another lot's invoice of 752.0 the same reading shows -4.5 and looks wrong. Compare only with the lot's own invoice.
Normal petrol sold as branded
Selling normal petrol as branded fuel on purpose is a major irregularity MDG 5.1.10 MDG 8.3; the penalty is on the branded fuel page. A branded sample must still meet at least the IS minimum for petrol MDG Annexure 5.
Questions dealers ask
01Power petrol vs normal petrol density: is there a difference?
Not in MDG's ranges. It prints one petrol range, 720–775 kg/m³ at 15°C, and no separate premium row MDG 7.6. The density of your own lot is on its invoice MDG 2.2.1(iv).
02Power petrol ki density kitni honi chahiye?
MDG sets no figure for Power or any brand. Petrol is 720 to 775 kg/m³ at 15°C MDG 7.6, and your reading must be within ±3.0 of the invoice MDG 1.2(iv).
03What is the density of HP Power petrol?
MDG does not name HP Power or give it a range of its own. The petrol range is 720–775 kg/m³ MDG 7.6. Your lot's exact figure is on the invoice MDG 2.2.1(iv).
04XP95 density and Speed petrol density: which range applies?
MDG names neither. The one petrol range it prints is 720–775 kg/m³ at 15°C MDG 7.6. Ask your oil company which MDG grade a brand matches.
05What is the premium petrol density range?
MDG has no premium range. Its petrol table has lines for MG 91, MG 95 and MG 98, but density is one figure, 720–775 kg/m³ at 15°C MDG 7.6.
