What rating system do they use for gasoline/petrol in Thailand? RON (Research Octane Number), MON (Motor Octane Number), or PON (Pump Octane Number)?
Pretty sure it isn't RON. Think it might be PON, they average of RON and MON, the same as they use in the US. I am interested to know because 91 and 95 are just numbers and are not indicative of the fuels qualities without a standard.
