Prem is $.60 more than Reg here. Used to be $.40 a couple of years ago. Now that more and more cars need it, it will probably go up to whatever the market will bear. $1.00 more than Reg is highway robbery, but if people will pay it, it wont go down and might even go up. Remember the price of diesel during the pandemic? Two out of three of our cars require Prem.
Premium Fuel $1.00 (or more) Higher

The cheap station is $3.85. higher priçed is $4.60ish. goffs and ludlow are still $8+
My local area has drifted every 2 weeks like clockwork between 2.49-$3.00. It slowly drifts down but then Sunday around 5pm everyone cranks it back up in price. Ask the local oil mafia why they do that in lock step, I'm interested to know myself.
Central Pennsylvania, we have 93, usually always about $1.00 more. Lately prices for 87 have gone up 40 or 50 cents, now are slowing dropping into the $3.159 range. Our gas tax is about. .58/gal
Yeah, I hate that, and my car doesn't even use premium! 
Depending on the size of your tank, it's actually cheaper to use octane boost with 87 than it is to buy premium. $11 for a can at Walmart that claims to boost by 5 full numbers (50 points).

We have an ExxonMobil station in my area that charges as follows
87 regular 2,999
89 midgrade 3.199
93 premium 3.299
on road diesel 3.399
The only gasoline is use is 93 for the Corvette. The price is 35 to 70 cents cheaper than other station"s 93-94
And the diesel, for the BMW, is also at least 40 cents cheaper.

It’s a bummer too because using higher octane will also lead to lower fuel dilution usually, since less fuel is being used.
'Back in the day' the industry used the Research-method octane number to advertise their gasolines; that number is, generally, about 10 points higher than the number produced by the Motor Octane method.. For decades, the Feds have required the 'Antiknock Index' be used to label gasoline; that's the '(M + R)/2' label now posted on your gas-filler door.. Different times and systems, different numbers for the same stuff.
This situation is similar to horsepower ratings; we used to use SAE Gross horsepower, but now we use SAE Net horsepower.. The SAE Net number is usually about three-quarters of the Gross number.
Kwik Trip around my parts charges exactly $1.10 more for E0 91 octane premium than it does for 87 octane E10. I use the good stuff exclusively in my Seville, although it would probably be fine running 89 with a 10.3:1 CR. I just don't care to have ethanol running through 30 year old fuel system components.

See post #1. 89 will often get a turbo engine to its max output. On my CX-5, I get the best balance of power and fuel efficiency on 89. I’ll use 91 or higher when I want to really get into it, I.E. large, long hills on a trip or towing.
My 6.2 Silverado is 91 recommended. I alternate between 93 and 89 every other fill up. I usually top off at half tank. Plus I never know when I'm going to have to tow something.
$3.32 for regular here in the NY ADK's without member discounts. $3.63 for 89 and $4.02 for 93.

Interesting about the 6.2. I also recall some model years asking for 93.
It's usually around a $1.00 higher in my area, both PA and MD (I'm right on the line). The WRX requires premium and the '24 Tacoma seems to run better on it, so I use it in both. I don't drive a whole lot so the extra cost is negligible.
My previous turbo car ran terrible on 87. Had to use 89 to straighten it out. No choice here.
I didn’t think about that.
My Elantra N has an “octane learning” system in which the ECU resets boost and mapping/timing to lowest levels on every fillup. Then, if no knock is detected, timing & boost are “unlocked”, allowing a few more PSI of boost, and more aggressive ignition timing, which supplies about 20-25 more HP.
I should try 89 and see if it’ll get octane learned on that.
It's hit or miss here. I suspect the reason for the high premium prices maybe be do to less vehicles then ever use premium? Those limited ones that do use it, the station itself isnt concerned with drawing you in to fill up.
Lowes Food Store is a winner around here but since Shell is cheap I use that when I can. Our only use is regular gas. Im posting this for others to compare. Current as of 9/2/2025
