lead-free fuel

But if you have a tight budget and a conscience, running older cars on lead-free fuel becomes a much more complicated issue.

Although newer cars are built to run on lead-free fuel, leaded gasoline is still available and widely used.

The British petroleum industry has claimed that it is uneconomic to produce 97 octane lead-free fuel.

More advanced ignition timing, and the lead-free fuel required with the converter, prevented exhaust-valve failure.

The manufacturers want the burden of making the change to lead-free fuel put onto oil companies who could, at a price produce substitutes for lead in petrol.

Many classic cars' engines have needed modification to use lead-free fuels since leaded fuels became unavailable.

Lightweight, and with a powerful airstream, the BG 72 has a two-stroke engine which runs on lead-free fuel.

'A recent RAC survey showed that nearly six out of 10 car owners don't know if their car can run on lead-free fuel.

Compression ratio for the standard and optional engine is 8.0:1, as the engine was designed for low-lead and lead-free fuels.

Use all the Corrado's ample performance and the lead-free fuel flows through the intakes at the rate of around 22mpg, and this shows little sign of improvement even when driven more gently.

However by the late 1960s as wealth increased car sizes were rising despite heavy fuel taxes, although some of the more upmarket brands were building cars that could take lead-free fuel, and there were still a number of "economy" cars in production at this time.

The company told their US dealers that modifying their cars to meet new US federal safety and pollution requirements would be prohibitively expensive, while experience elsewhere suggests that the Rover four-cylinder engine was particularly hard to adapt for reduced octane lead-free fuels without an unacceptable reduction in the car's (already mediocre) performance.
