Purchasing the right petrol is sometimes very confusing. Each retailing company has its own brand names for the fuels they sell at their stations and the petrol itself is available in 4 diverse flavours which are generally known as 91,95,98 and E10 including E85 on the odd occasions. Please take note that it can be very confusing as to knowing which one to purchase.
WHAT IS THE RIGHT PETROL FOR MY CAR’S ENGINE
Please underline and understand that the numbers are what matters. Standard unleaded petrol is 91. Premium unleaded petrol is both 95 and 98. Also be informed that the ethanol-blended E10 (mixture of up to 10 percent ethanol in petrol) is a substitute of 91 in most cars 2005ish or newer.
The foregoing numbers – 91, 95 and 98 are the so-called octane rating of the fuel and they are all about the same in terms of the energy in the fuel. Be informed that what the octane really is, is an index of a fuel’s resistance to burning too early inside your car’s engine. The moment that occurs, it triggers pinking or pinging which is mechanically very devastative at high revs and colossal throttle openings.
Manufacturers of cars design for minimum octane rating. Now whenever you open up you’re the fuel flap of your car and it says ‘unleaded petrol only’ it means 91 octane fuel is OK. If your fuel flap tells you ‘premium unleaded only’ it is telling you that you need to purchase at least 95 for your engine. Again if the fuel flap of your car informs you to sue 98, that is exactly what you need to do.
It cannot hurt your engine if you use a higher octane fuel. For example, if you always purchase 95 or 98 for your car engine designed for 91, that is OK. But take note that it is highly not acceptable to put in a lower octane fuel than the minimum recommended by the manufacturer of the vehicle. Purchasing 91 for your engine which is designed for 95 or 98 is potentially destructive.
