Differences between fuel types
|E10||Ethanol 94||Fuel is 10% ethanol and 90% unleaded petrol, octane rating 94. Ethanol is made from fermenting plants, such as wheat and sugar cane.|
|U91||Unleaded 91||Standard unleaded petrol, octane rating 91.|
Fuel is 70-85% ethanol and 15-30% unleaded petrol, octane rating 105. Only for cars built or modified for it.
|P95||Premium 95||Premium unleaded petrol, octane rating 95.|
|P98||Premium 98||Premium unleaded petrol, octane rating 98.|
|DL||Diesel||For diesel engines only.|
|PDL||Premium Diesel||Diesel plus additives for cleaning and efficiency.|
|B20||Biodiesel 20||Fuel is 20% “bio” (often vegetable oil) and 80% diesel.|
|LPG||LPG||Liquid petroleum gas or autogas. Only for cars modified for it.|
|CNG||CNG/NGV||Compressed natural gas. Only for cars modified for it.|
|EV||EV charge||Electric vehicle charging station. Only for electric vehicles.|
What is octane?
Octane is an index of fuel’s resistance to burning too early inside the engine. If that happens, it causes destructive ‘pinging’. Higher numbers have more burning resistance than lower numbers. For example, P98 has more burning resistance than U91.
