The Stinger Fuel Thread

The engine is not more efficient on higher octane gas, it is just capable of producing the most power.

Not in the sense of making it more efficient than how it was created from the factory.

But yes, it is more efficient running Premium fuel compared to Regular fuel. Simply because it doesn’t have to work as hard to make the same amount of power. Less throttle(pedal input) to achieve the same amount of acceleration by definition is more efficient.

More power=less effort, RPM and fuel needed to achieve the same performance. That’s more efficient in any sense of the word and why similar high performance engines gained up to 15% better fuel economy in the AAA tests.

Just, damn..

It depends on the type of efficiency you are referring to. If one is referring to thermodynamic efficiency, running higher octane gasoline allows more aggressive ignition timing. More aggressive ignition timing increases cylinder pressure during the power stroke. Increases in cylinder pressure during the power stroke results directly into higher engine efficiency. In this arrangement, the amount of fuel injected into the engine remains the same, however the timing of the burn rate to maximum cylinder pressure is set to occur closer to TDC. This makes maximum power for a given amount of fuel. So the engine is more efficient and makes more power in this case.

On a side note, does anyone know if the Stinger uses any form of "lean cruise" where the fuel mixture is leaned out during low load cruising?

For me few cents is no deal at all so buy premium don't have the time to waste in thinking should I buy regular vs premium? I just put premium and just drive away.
