A Riddle

According to the government the tax on pertrol is so high to ptotect the environment and lower pollution.

According to the scientists, petrol companies and even the government itself Super Unleaded petrol produces 10% less and gives better fuel consumption.

According to the car manufacturers Super Uleade can be used in any petrol engine, prolongs the life of the engine, gives better fuel consumption and allows the engine to run 10% cleaner.

So do you tax it at the same level as normal petrol and make it too expensive to use, as Gordon Brown does?

Or do you reduce the tax so it is 25p a litre cheaper than unleaded so everbody uses it and pollution from cars drops 10%?

I guess it depends on if you are trying to reduce pollution or just trying to raise as much tax as possible.
