OCTANE RATING

NOTES

Federal law requires that gasoline octane ratings be posted on the pumps.

Jaguar Land Rover Limited recommends the use of premium unleaded gasoline with a minimum octane rating of 91 AKI (Anti-Knock Index) to contribute to peak performance, fuel economy and driveability.

If premium unleaded fuel is not available, you may use unleaded fuel with a lower octane rating, down to a minimum of 87 AKIĀ , but this may reduce engine performance, increase fuel consumption, cause audible engine 'knock' and other driveability problems.

CAUTION

Do not use fuels with an octane rating lower than 87 AKI as severe engine damage may occur.

If a heavy persistent engine knock is detected, even when using fuel to the recommended octane rating, or if you hear engine knock while holding a steady speed on level roads, consult your Retailer/Authorized Repairer to have the problem corrected. Failure to do so is misuse of the vehicle, for which Jaguar Land Rover is not responsible.

NOTES

Occasional, light, engine knock experienced while accelerating or climbing hills, is acceptable.

CAUTION

Use high quality fuel that meets the specification defined by EN228 (or the national equivalent).

CAUTION

Do not use leaded fuels, fuels with lead substitutes (e.g., manganese-based), or fuel additives, as these may adversely affect the emissions control systems, and may affect warranty coverage.

Using unleaded fuel with a lower than recommended octane rating, can cause a persistent, heavy engine knock (a metallic rapping noise). If severe, this can lead to engine damage.
