Fuel Quality & Specs
The limits a fuel must meet to be sold, set by national standards and regulations, and the sampling that checks them along the supply chain.
What it does
Products share pipelines in batches that mix a little at the edges, so fuel is tested as it leaves the line, and product that fails spec goes back to a refinery. In Canada federal regulations limit sulphur in gasoline and diesel and benzene in gasoline.
Basics
| Gasoline sulphur | 10 mg/kg pool average (since 2017) |
| On road diesel sulphur | 15 mg/kg (since 2006) |
| Gasoline benzene | 1.0% by volume at supply, 1.5% at sale |
Common failures
- Cross contamination at a terminal or truck compartment, such as gasoline in diesel

- Symptom
- Wrong product found after a delivery
