Gull Regular 91

The most popular fuel in Gull's inventory, Regular 91 is refined to meet the requirements of all spark ignition engines.

Gull Regular 91 octane petrol contains no ethanol, and is less than 50 parts per million of sulphur. This means it is effectively the cleanest burning grade of petrol out there, makingour most popular grade compatible with all cars and boats in New Zealand.

It delivers the same economy as any other 91 octane petrol out there on the New Zealand market but has one key difference: we charge less for it, end of story.

And as with all Gull fuels, Regular 91 is warranted to meet New Zealand Fuel specifications but are proud to say that we often exceed them by quite a bit.

Gull Force 10

Powering the BNT V8 SuperTourers and New Zealand’s top rally drivers, Gull Force 10 is a high performance 98 Octane fuel that is designed to start working the instant it enters your engine to help remove performance-robbing deposits.


Gull Force 10 is a high performance 98 octane petrol, used by the BNT V8 SuperTourers and every day motor enthusiasts alike.

Gull Force 10 contains 10 per cent ethanol. This is locally made
by our dairy industry, reducing our dependency on imported fuel and supporting the rural New Zealand economy.

Gull Force 10 emits up to 8 per cent less carbon dioxide than
other high octane petrols, and has been endorsed by EECA as an environmentally friendly fuel. It’s a fuel that creates up to 8% less carbon dioxide and because it burns more efficiently, provides extra power you can ‘feel’, and cleaner air for all of us. Over the last few years, we’ve pumped enough ethanol to fill more than eight Olympic swimming pools and saved our Kiwi air from more than 3 million tons of carbon dioxide. 

The ethanol in Gull Force 10 is a renewable bio-fuel that’s more sustainable – so you can enjoy more power and do your bit for the environment, it’s as simple as that.

Gull Force 10 will naturally remove water from your fuel system and contains anti-corrosive additives to protect your entire engine system. All fuel tanks generally contain some
water generated by condensation, with older vehicles more likely to have water in the tank. Gull Force 10 will actually clean the water from your system. Combine this with the anti-corrosive additives we use and you have a fuel that not only performs well, but looks after your engine too. The end result is that it is firing on all cylinders, all the time. Don’t you love that?

Gull Diesel

One of Gull’s flagship products. Gull went “low sulphur” well before legislation required it or the oil giants thought it was a good idea. Still with low sulphur content of 50ppm Gull has reduced this down to a tiny 10 parts per million at the end of 2008.

Applicable for: heavy transport, industrial, heating, light commercial, diesel passenger vehicles and marine use; Gull Ultra Low Sulphur Diesel remains a star performer across many categories.
