Know your petrol types: why regular might be better than premium ULP
With petrol prices at record-highs, motorists are being tempted to opt for the cheapest fuel. But is it worth it in the long-run?
Standing in the petrol forecourt and looking at the big signage board advertising prices, the conclusion many are coming to to save a few pennies is to change the type of petrol put in the tank.
Car companies research and develop engines to run on a fuel with a specific octane rating.
The octane rating (technically known as Research Octane Number, or RON) is essentially how much heat and pressure the fuel can withstand before it ignites. That’s why performance cars using engines with a high compression ratio require fuels with high RON values.
In general, European-built cars typically require 95 RON fuel, while performance vehicles will probably be tuned to operate on premium 98 RON fuel.
Most Asian-built cars are designed to operate using the cheaper 91 RON fuel and E10, an ethanol-infused fuel, can be used in most cars (the owner’s manual will confirm this).
