Survey of Engines and Engine Management Systems The octane numbers in bold face in the following table indicate the production recommended fuel for the engine in question. Footnotes and abbreviations for the following tables:
|
1) |
If premium unleaded fuel is not available, use of regular unleaded fuel with RON 91 is possible if high engine loads and driving at full load or in mountainous regions with trailer loads or high payloads are avoided. |
|
2) |
Stricter limits as of 1996 (EC 96) |
|
3) |
With catalytic converter, this engine also meets the particle limits of 0.08 g/km. |
|
4) |
If RON 87 is used or, for X 16 SZR engine RON 91, slight output and torque loss |
