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.

Do you get better gas mileage by car if you use higher octane gas?
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...
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.
What octane for a kawasaki kz900?
i found with mine, that if you used 91 octane you get worse gas mileage than with 87, you also have to remember the KZ models are old and when they were running the streets the most common gas was 87 octane 91 was pretty much race fuel. so if you want better mileage i would probably go with 87.

it will only if your car requires 89. If your car is designed for 87, then 89 will provide no benefit.
What are two ways to increase a fuel's octane rating?
Octane rating is simply a relative measure of how much octane (which is a chemical substance) is contained in gas. The only way to do it properly is to buy higher octane gas. But buying higher than what your manual recommends is completely pointless. Contrary to popular opinion, you will NOT get more power, you will NOT get better mileage, and it will not run your engine cleaner.
What gives more mileage diesel or petrol?
It obviously depends on the cars being compared but generally Diesel provides better gas mileage.
Do you get more miles with super unleaded gas?
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.
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.
