Why do we even have middle gas?



There are three types of gas on the pump that are likely to scratch your head: Midgrade, typically 89 octane. Very few cars in fact, almost certainly not demand your among the ten for 2018 specifying it as their diet.

Sales at the pump reflect that with 83% of gallons we come from the regular pump, 10% from Premium and only 7% from Midgrade Button

Why is there midgrade gas?

What Midway sales are likely to be mainly from ordinary customers who think they are doing their car a favor, doing a little more work or making it longer. Everything generally wrong. In fact, using a higher octane fuel than your car requires will not increase its performance or efficiency, although you will sacrifice some power and efficiency if you use a lower octane rating than you would expect for its long shelf life. 19659002] Recently, GM, Ford, and Fiat Chrysler have begun advertising US $ 95 Research Octane for a single higher-octane fuel, so they and other automakers can develop smaller, more efficient, high-horsepower engines that require such fuel save from self-destruction. Consumer groups complain that we get soaked for fuel that can consume 50 cents more per gallon than normal; Automakers say we will earn it again in higher fuel efficiency, suggesting that they can improve MPG by at least 20% to reach the cost delta.

Refineries could bring savings because they have a simpler range of grades to refine, truck and market (yes, right), but the number of older cars on the road seems to require several degrees for decades.

If you're confused about the concept of fuel octane in general, see this video that explains it and exposes myths that can cost you money.

When the prospect of mandatory premium gas boggles through, you know what your car really needs today: the manual will spell it and there's probably a sign on the fuel filler flap. A few cars offer two options: a "suggested" and a "required" class, in which case I recommend the higher level for optimal performance and MPG. In no case should you buy a higher mark than mentioned in the documentation of your car.
