It is an indicator to tell the driver that he is driving in such a way that he is getting good fuel economy.
No way ! Do not mix petrol with diesel it will ruin your diesel engine and be a very costly repair job.
the 2nd generation is nearly identical to the Porsche 944 in every way except fuel economy (rotaries get very bad fuel economy)
Most cars sold today state their fuel economy on their website. So the best way to do this would be to get out a pen and paper and write down several cars fuel economies.
You could try a fuel catalyst. They're different than fuel additives because they actually help your engine burn fuel more efficiently. The one I use is Fuel Infusion - www.fuelinfusion.com and I see about a 10-15% increase in MPG. Others have reported larger gains. Anyway, besides good car maintenance, a fuel catalyst is a cheap way to increase your gas mileage. Good Luck!
No Peru had good economy all the the way up to 2008. For 7 years they had good economy but then the economy went bad in 2008. I don't know that economy rate is right now. But it is not there best.
Yes. But in doing so, you will not notice a difference in the way the car runs. The higher octane rating is simply its resistance to pre-ignition. It doesn't increase your fuel economy. All octanes have the same amount of energy in the fuel.
Depending on how good the fuel economy of your car is, and how much does the gas cost, the average price for a one-way trip would be about $20.
No, the opposite is true.
cut taxes to increase investments

The U.S. economy was rapidly pulling its way out of the Depression because new jobs were being created to help fuel the need for military supplies around the world.
