In many cases, mileage plus will improve octane levels. However, gas usage will depend again on driving conditions, i.e., highway vs. street driving; stop-start traffic and of course short trip drives taken many times.
According to the owners manual, the Windstar is happy with plain 87 octane. Anything higher is not necessary, and doesn't improve performance or mileage.
That depends on what the car was designed to run on. If it was meant to run on 87 octane, using 89 octane can make the mileage worse.
High octane gasoline (petrol) only provides better fuel mileage in vehicles that require the high octane. In a normal engine running higher octane provides no benefit.
Yes, higher octane gas does give higher gas mileage for your car. However, the increase in gas mileage may not as great as the increase in the price of the higher octane gas.
A Chevy Avalanche uses standard 87 octane fuel. Higher grade fuel will not result in improve mileage or performance.
Not unless the engine using it was specifically designed for it. Gas mileage takes many things into consideration, and if a car is designed to use standard octane gas, the use of high octane gas will not increase the car's mileage - it is just a way of figuratively blowing dollar bills out of the tailpipe.
Yes. The higher the octane rating, the better the mileage you are likely to get.
Actually the higher the octane level the poorer the gas mileage. This is because the higher octane fuel burns slower and less efficiently for that particular engine. I agree 100%. The oil companies use the term Super or Premium to entice you to buy the higher octane fuel. It is a myth that it provides better mileage or more power. Use exactly what your engine was designed to run on.
Exactly the octane the engine was designed to run on. If your owners manual says, 87 octane, then use 87 octane. If it says 89 then use 89. The use of a higher octane than the engine was designed to use is a waste of money, and will provide no benefit whatsoever. No better mileage, no more power, nothing at all. It is a myth that running premium in an engine designed for regular will improve performance.

The gas octane that would be the best in a Honda CR-V from 2009 is 87 octane. Higher octane gas will improve its performance, but it is only necessary to have 87.
No. If your car runs well on a lower octane gasoline (i.e. no engine pinging or knocking), then putting a higher octane gas in your tank is just wasting money...
