Hurricane Fuel Octane

ExxonMobil, Sonoco, BP, pretty much anywhere here in the Northern VA area. A dollar a gallon from perfectly fine 87 to overpriced 93. I have a 33 gallon tank, I don't know if the Hurricane truck will offer this.

Well, YeeeHa little doggie! We ain't all in oil country son! Some of us non-cowpoke fellas have to pay to have that distilled oil piped up to us! 😆

Well Mountain, that's a cousin, mother, sister, wife lovin shame, hooo-weee
 
Yeah this was the justifying and delusion i was talking about per usual here... Your trying way to hard and getting way to deep into it. 99% of folks on here use their trucks as intended or daily drives. None of us will use it as "best performance" meaning its max power, nearly ever. It will be slim to none, and "fuel efficiency" were talking nearly nothing or all in your head. (like most of the stigmas on this forum) I will speak from experience with the hemi like the rest of us have though.. as ive tested it and why i usually shut down this topic with people i talk to b.c welp... ive done it both ways. i drive my truck from my house to my parents house out of state, from the stop i fill up a full tank outside of my city, to the gas station down the street from my parents house, my gas light literally turns on as im rolling in and thats with 87. I did it with 91 as well, want to guess the result? bingo. gas light turned on as im rolling into the gas station. SAME exact scenario when towing my boat and all the other crap in the truck, from my house to the river i go to. i fill up at the gas station down the street from my house and land at the gas station i stop at when getting to the river with exactly a quarter tank left with 87. want to guess what the level indicator is at with 91? you guessed it again, quarter tank. Thats keeping the same fuel avg obviously AND driving the same way with both octanes... since then i have always ran 87. No point in wasting money. i am positive the Hurricanes will be the exact same thing like @Mountain Whiskey is stating.

again i do not disagree if its at MAX power, sure, but thats not a reality for most owners.

just say its what YOU do or will do. That would be better.
Did you document the temperature and wind speed on each trip? It probably will effect mpgs the most but retarding the spark to stop knock will effect efficiency. How much, I don't know. Maybe an actual engineer will speak up and help us out without telling all of us, that we're all stupid.

Oh Lord, don't let the engineers overcomplicate things with paper outcomes that are so miniscule the real world passes them by with no notice.

Kind of like air temperature affecting milage......

With it log files showing LTFT/STFT and knock retard it's all speculation
 
Not sure why the engineer would contradict what they print in the owners manual or why the Ram manual would end up being different than the Wagoneer manual. The Wagoneer manual does not say 89 is acceptable in the HO; it requires 91. For the SO, 87 is acceptable, but 91 is recommended for higher performance under certain conditions.

Given my experience with the 4 Hemi Ram's I have owned, I tend to doubt claims the manual makes about getting better fuel economy with higher octane. I've spent many months running nothing but higher octane fuel in my Rams and never got any better economy than I did running 87 octane.

In my area there is a $0.51 difference between 87 and 91 octane so it would take a 2 mpg difference in fuel economy just to break even in fuel costs.

So if the octane is > 100 what is the issue with e85 ?
 
I didn’t realize even the SO hurricane has a “like” for the higher octane fuel. There is a substantial difference in price near me between 87 and 91, often approaching a dollar a gallon, and so that essentially undoes any fuel economy achieved by the turbo six on a cost per mile basis if you live in an area that is hot or have any sort of load aboard. To be fair, the hemi will ping on 87 in those same conditions, but it resolves on 89. Seems like the turbo six needs 91 for any issues to resolve. Thank you EPA!
 
It is not all about octane and MPG. Higher octane fuels usually have a better additive package that contain friction modifiers that reduce engine wear. You also have more cleaning power in premium fuel.

Any top tier fuel regardless of octane will have good additive package. You don't need to run premium to get that if you choose the right brand.

I would be running 91 regardless, because I want the best performance. I'm not driving it for fuel mileage.
 
Costco's high test in my area is 93. It's either 93 or 87, so I do 2/3 87 and 1/3 93 on fill ups.

Nice!

In CA, it's 87 or 91 only. I will on occasion do 91, then wait half a tank and fill up again with 87 to create 89. I wouldn't dare do it at a single go, the people in line would probably try to purge me. They already freak out if you have to swipe your card twice because the reader didn't read it the first time lol.

IN NJ you are not supposed to pump your own gas, one Costco in south Jersey won't allow you at others I can. I pump faster then if I sat and waited for the attendants.

I remember running into that when I travelled to Oregon and started to grab for a pump handle, lol.
