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.

Does higher octane gasoline give you better gas mileage?
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...
What gives better gas mileage 89 or 87 octane?
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.

Should you run premium gas in a car that does not need it?
From what I understand, there is really no benefit from the higher octane fuels in a car that does not require it. Most manfs suggest the appropriate octane level. It is not recommended or better to use a higher rating. You may find, depending on your car, that you get slightly better mileage. Consider the length of the hose from the storage tank to your gas tank and wether you are getting all of the grade you have selected! Most manfs suggest the appropriate octane level.

Will 89 octane give you better gas mileage than 87?
it will only if your car requires 89. If your car is designed for 87, then 89 will provide no benefit.
Will mixing 87 octane gas with 91 octane gas affect your car?
not at all you're essentially making 89 octane. Using a higher octane than the engine was designed to burn is a total waste of money. It will provide no benefit whatsoever. No better mileage and no more power. It is a myth that is does. In fact on modern cars it may make it harder to start. Use what is recommended by the manufacture.
Does high octane gas increase mileage?
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.
Can use 89 octane gas in passat?

It is a myth that higher octane is better.
Do you really need to put the highest octane gas in your car?
If your car says it requires gasoline with a specific octane rating ... Well, it will probably operate with a lower octane rating, but it will be very bad for the engine and for your gas mileage. However, you don't need to use an octane rating any higher than your engine specifies, and there's likely no real benefit to doing so.
Does it help to use octane rated higher than your vehicle requires?
No. * Added - Unless you are prepared to modify the tuning of your engine, the recommended octane rating is the best. Higher octanes do not provide more power, they simply burn slower. The higher the octane, the harder it is to ignite, which in most cases, will have no effect, but can make make the car harder to start. If you have an older car and have the equipment to adjust your vehicles system, using a higher octane fuel can result in higher gas mileage and more power. It requires that the spark timing be advanced to begin burning slightly sooner - and if a lower octane is then used with the same set-up, it can destroy the engine.
