Sixty to one (60:1) is a ratio used by high performance 2 stroke motors. The ratio is not the easiest 2 stroke ratios to calculate.
To make it easier you can use the following old school reference chart.
| Fuel (L) | Oil (mL) |
|---|
| 1 | 17 |
| 2 | 33 |
| 3 | 50 |
| 4 | 67 |
| 5 | 83 |
| 7.5 | 125 |
| 10 | 167 |
| 15 | 250 |
| 20 | 333 |
| 25 | 417 |
