We were coming back from Half Moon Bay and were out of gas, so we went to the gas station just near Alok’s house. While Alok was filling up the tank, I just happened to see these three types of gasolines written and I was just shocked ! Till now I hadn’t seen this !

What was the purpose of introducing unleaded petrol. It was encouraged to reduce environmental pollution caused because of lead compounds. Hydrocarbons and alkenes are added to unleaded petrol instead of lead compounds to increase the octane rating. So the whole purpose is to reduce the harmful lead compounds. No doubt the latest cars require high octane petrol, still nobody likes to pay more for gas.

Then why make three levels of octane content in the unleaded petrol. When the purpose is reducing environmental pollution, then why make three and sell them at different higher rates. Government should bare the extra expenses in making it octane rich, so that we customers need not bare the extra price for the higher octane rating gasoline.

Unleaded is at normal gas price, unleaded plus is 10 cents more than normal and super unleaded is 20 cents more.

We should understand that its not a single person’s contribution to reduce pollution, everybody should contribute equally. If they keep three types of gasoline’s and the highest octane gas is the costliest , then nobody would like to fill their tank with that gas. Yes, I don’t say no to the advantages of the “Super Unleaded” to the engine. But when there is huge difference between the three different gas prices.

Government tries to give gas at reduced price, still they should also take initiative of bearing the extra cost of making it octane rich(super unleaded) and sell the gas at normal gas price.
