The Utility Regulation and Competition Office (‘OfReg’) of the Cayman Islands confirms that there are 11 Rubis and 11 Esso (SOL) petrol stations in the Cayman Islands, all with attached convenience stores.
There is only one independent retail station, Refuel, located on Grand Cayman, which markets ethanol-blended gasoline and biodiesel blended fuels. There are also 5 marina retail stations located across Grand Cayman.
As of 4th July 2023, the average full-service price for premium, regular and diesel fuel was CI$5.92, CI$5.75 and CI$5.38 per imperial gallon (IG), respectively, although prices vary from one station to another. The fuel prices in the Cayman Islands are influenced by the price of fuel on the international market. Self-service petrol prices are typically 5¢ per IG less than full-serve prices. Weekly prices for retail fuel across the Islands are posted on OfReg’s website: www.ofreg.ky. The (import) duty component of gasoline is 75¢ per IG and 85¢ per IG for diesel.
The quality of gasoline sold in Cayman is equivalent to a mid-grade unleaded (octane level 89) and a super-premium unleaded (octane level 93) often sold in the US. Some high-performance cars will experience problems if they are not run on the highest octane fuel available.
Scotts Landing, at the Barcadere Marina sells only premium Valvtect Marine fuel. Valvtect ultra-low sulphur diesel and premium 93 octane ethanol-free gasoline is specifically formulated for marine engines but will also help to increase fuel mileage and protect the engine in your vehicle, generator or other equipment as well. Cayman Islands Law states that all fuel stations must display their fuel prices in CI dollars per imperial gallon, except at marinas, where prices must still be displayed in CI dollars per imperial gallon for comparison purposes but may be dispensed and charged in US gallons (which is approximately 20% less per volume than imperial gallons).
