A month later, in January 1965, the final drive ratio reverted to the 3.88:1 value used in the prototype, from the 4.2:1 ratio applied at launch: this was described as a response to "oil-consumption problems". The same month also saw the indicator switch modified. [4]
The chatter marks, nicknamed "devil's fingernails", were caused by the tip-seal vibrating at its natural frequency. The oil consumption problem was addressed with heat-resistant rubber oil seals at the sides of the rotors. This early engine had a rotor radius of 90 mm (3.5 in), an offset of 14 mm (0.55 in), and a depth of 59 mm (2.3 in).
Notwithstanding the growing effects provided by the automobile on the economy of some countries, countries specialize, exporting some products and importing others. Several auto-dependent countries, lacking an automobile industry and oil wells, must import vehicles and fuel, affecting their commercial balance.
As for the global usefulness of the Hirsch conclusions, as of 2004, the US share of global oil consumption was about 26%, while its share of the world population was only 4.3%; Europe used 11% of global oil while having about 6.8% of the world population. An average car in Germany uses about 8.1 liters per
Oil may leak into the groundwater and the common practice to clean cars in the front yard causes surfactants and other products in the cleaning products to pollute the ground.

Following the 1950s and 1960s — the unregulated decades when the U.S. automotive industry could prioritize unrestrained horsepower, [2] size and styling — the Malaise Era arose after the Clean Air Act of 1963 began to codify a legislative response to serious national car-generated air quality concerns, and Ralph Nader's 1965 Unsafe at Any Speed galvanized attention on U.S. automotive ...
In the latest CPI report, fuel oil was up a whopping 3.0% for the month, even though it crashed 26.5% year over year. Similarly, utility gas was up 2.0% in July but down 13.7% from a year ago.
Fuel consumption monitor from a 2006 Honda Airwave.The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle.
