Doing away with 89 octane?

It makes sense. I don't know many cars that specify 89 octane. It's either 87 or 91/93. Our Costco only has 87 and 93. I'm guessing 89 is for cars that start pinging as they get older. If somebody really needs 89, they can make their own blend.
A few quick stops around here have also done away with 89 oct. I thought it odd, but perhaps it is due to it being the lowest selling grade. Honestly, I haven't a clue.
My car recommends 91 oct. min. During the warmer months when I'm likely to tow, I use 93 oct., and during the winter, I alternate fill-ups (only add 10 gal. to simplify mileage calc.) when l'm down to about 6 gallons in the tank (guage marker, also used for fuel mileage trip point), between 89 and 93. A slight cut in costs, and perhaps some gain in mileage potential since I'm light on the peddle. Again, it's more of a hunch and penny pinching measure. Us analytical types!
I too am interested in what others have to say.
BTW, my '95 volvo 850 wagon with non-t 2.4l averages around 21-23 mpg, mostly short city trips, occassional highway and joy rides. 92K on the clock, purchased used with 65K. Been using m1 5/10w-30, tried m1 0w-40, rotella t 5w-40...soon to try GC 0w-30.

Around Detroit they have 87, 89, and 93. Often the price increment is the same from 87 to 89 as from 89 to 93, so if you instead mix 50/50 87 with 93 you pay the same price and get about 90 octane. A lot of hassle, but maybe worth it.

I say good riddance! No use keeping a grade around that nothing specs.
Back in 2000, some of the newer Citgo stations in Northwest PA (Country Fair) had 87,88,89, and 93 Octane.
Anyone else remember the days of the Sunoco Dial pumps with 86,87,89,93, and 94 Octane?

Here in NY, about a year ago sunoco phased out the 94 octane.
We still have a couple places around here that carry 104 octane fuel, but its like 4 bucks a gallon, so its not worth it.

I use 89 in my jetski and lawn equipment.

My local Sunoco still blends in the pump, albeit push button style.
I think the evolution of the two grade gas station is one of practicality I still see stations have three tanks ..and tankers three compartments. I would imagine that the demand for regular is so high and mid grade so low in comparison, that the product just isn't worth the dwell time in the tank based on the $1/gallon costs involved and how many fewer wasted miles in deliveries if the two grade system is used.
You just don't turn the product over fast enough.
In our region, it's cheaper and yields higher octane to do a 50/50 mix. The spread here is about $0.14-$0.18 ..but the jump to 89 takes the brunt of the increase, typically $0.10-$0.12
If I gained anything from mid grade ..I guess I would just fill up at 1/2 tank and alternate. The octane would vary ..but the costs would be less.
