A few years ago, a former L7C member from Alberta ran a couple of tours for Caterham owners on the W Coast and invited members from the UK to join. I think about 6 cars were shipped and I think all was absolutely splendid and they all had a jolly time! One of the queries raised before they went was about the quality of fuel in the U.S. I didn't know, but apparently there is a difference in how the fuel is rated, the following may help, in any case I think your fuel is the same as ours. Europe vs the States In Europe, gas stations describe different types of gasoline based on their RON rating. It is typical to have 100, 99, 98, 97 or 95 RON with prices varying accordingly. In the States the descriptions look a lot like RON, but they are not. Pump gas In the United States gas stations describe the types of gasoline based on the Pump Octane Number (PON). That number is the average between RON and MON. This causes many problems. If a fuel is 98 RON then it will be 93 PON -> 93 PUMP If a fuel is 95 RON and 87 MON then it will be 91 PON -> 91 PUMP Brian
