It's not surprising that we no longer add lead to gasoline ( TIME magazine called it one of the world's worst inventions back in 2010). (mentalfloss.com)
When was the last time you thought about your choice of fuel? (rislone.com)
As mentioned earlier, a fuel stabilizer will help your fuel hold up over time. (rislone.com)
Knocking is essentially combustion at the wrong time. (environmentalistsforeurope.org)
Compression ratios have increased over time going from a value of 4 in the Model T to 12 in modern engines. (petro-online.com)
The United States regained the lead in automobile manufacturing in 1994, since by that time Japanese producers have been building extra of their merchandise in factories of their major abroad markets, such as the United States, in response to financial and political pressures in those markets. (manu-militari.com)
Tetraethyl lead in gasoline was phased out during the 1970's and banned altogether in 1995, but soil beds found near roads built before this time are still dense in contaminants such as lead among others. (planetprotein.com)
By this time, the plant was producing three grades of gasoline as well as supplying the purple-dyed agricultural fuel that wartime rationing prohibited for use in private automobiles. (pcwestvillagepartners.ca)
Why should I use Esso and Mobil branded fuel every time I fill up? (esso.ca)
At the time, "regular" gasoline contained tetraethyl lead, which served as an octane booster in fuel. (esso.ca)
If you normally use this kind of unleaded gas, fill up with premium next time, since higher octane fuel can help fix your engine. (rockhate.com)
Ensures your ability to obtain High Octane Race Fuel all the time. (klmperformance.com)

The higher the octane rating, the greater the engine's resistance to knock. (esso.ca)
Improve your engine's power output level by running the required grade of fuel. (klmperformance.com)

Within the early Sixties Chrysler experimented with a fuel turbine engine for passenger automobiles, however it had too many technical problems for normal use. (mlogic3g.com)
Often called " plug-in hybrids ," these automobiles can offer much-improved environmental performance and elevated fuel savings by substituting grid electrical energy for gasoline. (mlogic3g.com)

They function by, as the name suggests, adding substances, such as system cleaners, lubricants and performance enhancers, to the fuel to achieve a specific goal. (rislone.com)
They could be performance enhancers or fuel stabilizers. (rislone.com)
Fuel performance enhancers improve the functioning of your fuel. (rislone.com)
Detergency is the performance characteristic of a gasoline that refers to its ability to clean and protect the fuel delivery system, including the carburetor or fuel injectors, and intake valves. (esso.ca)
The strategy used in this protocol is to create the conditions which induce knock and compare performance of rated fuels under those conditions. (alanroth.net)
