Every gas station in the US I’ve ever been to has a tamper-proof seal from a regulatory body sealing the measurement mechanism for a fuel pump and noting the date it was last inspected. However, I have never seen an equivalent here in the Cayman Islands. How can customers be certain that the volume of fuel they pay for is what they receive? I would think it would be very tempting for an unscrupulous station owner to put a “thumb on the scale” or at the very least fail to recalibrate pumps which underdeliver fuel. Is there a process in place to protect consumers at the pump?


Advance ChevroletAuntie’s answer: I checked with the fuels inspectorate at the Utilities Regulation and Competition Office (OfReg) and a system is indeed in place to prevent any funny business when it comes to measuring fuel in Cayman.

All gas stations in the Cayman Islands are required to have their pumps calibrated. An OfReg fuels inspector explained that calibrations are conducted at least once a year as required under the Dangerous Substances Regulations, 2017. Before that came into effect, calibrations were still conducted to satisfy the public interest.

In case you were curious about the specifics of calibration, the inspector explained that it is done by a third party, meaning not a representative of the gas brand being checked, and witnessed by OfReg inspectors. Importantly for your concerns, he added, “Once calibration is completed, OfReg inspectors place tamper-proof seals on the inside of the dispensers so that calibration cannot be changed.”

In addition, the margin of error allowed for fuel station dispensing meters is only plus or minus 0.22%, as determined from guidelines provided by the US-based National Institute of Standards and Technology.

After the calibration is completed, a sticker is placed on the outside of the dispenser, stating the date it was done. The stickers are orange, carry the OfReg logo and are placed in the same spot on all pumps. Below is a photo of a sticker in place so you will know where to look.

However, if you cannot find a sticker, you can contact OfReg by emailing the fuels inspectorate at fuels@ofreg.ky. But the OfReg official also pointed out that the lack of a sticker does not mean the meter was not calibrated. “If the sticker is not in place, it will require some probing by OfReg as these are designed to remain in place once affixed. Regardless, the tamper-proof seal on the inside of the dispenser is the important component.”
