Maybe another poll option could have been 'Yes, to help maintain my engine'?

Not at all. It turns out that you are also pumping your car full of chemicals that sound as if they belong in your washing machine instead, going by names like detergent, lubricity agent (in diesel), corrosion inhibitor, demulsifier, antioxidant, anti-foamer (in diesel) and cetane improver.

What are they all for? Quite simply, to clean out the rubbish that otherwise accretes on the important parts of your engine, and to keep out other rubbish that might mess up its performance.

These days, additives are a potentially powerful marketing point. "Basic petrol is produced to a British standard" said a spokesman for BP (which is presently advertising its "Ultimate" fuel). "All the fuel tankers fill up from the same stuff at the depots." Often, BP tankers will go and fill up the tanks of supermarket petrol stations. "But they don't have the additives," said the BP spokesman. "The ones which are going to our garages will get a squirt of the special juice." There's not much -- less than half a gram per litre -- but it can make all the difference.
