Volkswagen Jetta vs. Toyota Corolla ??

[Big Frank]

I burn 91 in my turbo once in a while.  It is designed to make max HP of 248 on the grade and if I keep my foot out of and run at 65 for extended trips it gets better mileage!  My problem is like Franks!  It’s 40-50 cents a gallon more than 87 octane.

Now that you mention it, I think the price is about that much higher here too. A long time ago it used to be 10 cents difference between 87 and 89, and 10 cents between 89 and 91. Now it's probably around 20 cents extra for 89, plus another 25 cents for 91 octane. That puts it closer to $16 extra per tankful.

Yea, I normally fill at half tank, about 8 gallons.  Right now 87 is 2.60 and 91 is 3.10 up the street.  Funny thing though, I can drive five miles into CT and pay over 3 bucks for 87...and everything is 10% ethanol out here!

Just because it has a octane rating of x, does not mean you are getting that.  Remember you can up to 10% ethanol  in it, which only has 80% the btu  of gas.  I would never run any thing that "needs" 91/93 On the street as pump gas is very bad gas.   Even in my toys  that need  higher octane, I only buy it in cans or run 100ll.  Yes it cost more, but I know what I am getting, has is cheap compared to say a decent boat motor

The 2018 Toyota Camry has a 16 gallon fuel tank. My 2015 Jeep Grand Cherokee has a 26 gallon tank. And my 1991 Ford F-150 has 2 tanks. Each hold around 16.5 gallons. The most I ever put in it was 32.5 gallons.

So if I ran them all dry and filled them to the brim, I'm looking at right around 80 gallons total. 91 Octane Premium by me currently goes for $2.70 @ gallon. That would come to $216.00 to top off all 3 vehicles if they all had dry tanks.

True, the station where I pumped gas, like most, mixed high test with low octane fuel for their four grades of fuel.  The owner could set the mix ratio...

This was nearly thirty years ago but it still questionable.

More good reasons I'll stick with 91 Octane Premium in my new Toyota.... It probably is only 89 actual Octane. We can't get non Ethanol motor fuel in Phoenix. And racing fuel can sell for up to $10.00 @ gallon. When I lived in Lake Havasu City, a few stations in town had "Racing Fuel". The weekend boaters from California would fill their boats with it. I used it in my bikes. At the time it was $2.00 @ gallon when Premium sold for around a buck.

TAB’s too young to remember Sunoco’s 104 octane leaded from the seventies!  We ran it in everything at about 50 cents a gallon!  I could fill up my 65 Mustang with loose change found under the seats!

Ha!!!

[TAB]

No, but I remember the since 100 at the pump.  CARB finally killed that off.  Use to drive 13.2 miles each way too fill up the twin turbo  stang.  I needed 1.25 gallons too make it there.  Back 2hen every smog check the only thing that remained under the hood was the brake booster

We have several stations that still sell ethanol-free gas at around .30 per gallon higher across the board. One station calls it Marine gas and adds an extra .20 on top of that. I run that in my older truck that runs less and sits more and in my mowers. Non-ethanol helps prevent moisture in sitting fuel tanks.
We have one station that sells 100 octane fuel and the pump is locked and you have to get an attendant to unlock it.
My newer truck will run on the E85 (older one would too, but I never did it) but I stick to regular 87 with no issues unless towing our camper in the summer. Then I run 91 with no issues.
