Gull Regular 91 Octane petrol contains no ethanol and is less than 10 parts per million of sulphur. This means it is effectively the cleanest burning grade of petrol out there and compatible with all cars and boats in New Zealand which are designed to run on a minimum of 91 Octane.
The most popular fuel in Gull's inventory, Regular 91 is refined to meet the requirements of all spark ignition engines. As with all Gull fuels, Regular 91 is warranted to meet New Zealand fuel specifications, but we are proud to say that we often exceed them by quite a bit.
Gull Regular 91 is not a biofuel and contains no ethanol.
