What Octane Gas Do You Pump In Yor V6?

[sal jc]

A physical change to my wallet is not a physical change to my car, so it has no bearing on my original comment.

that was a joke :smash:

Regardless, your math is way off.
I drive ~10,000 miles a year. At a combined city/highway of 24mpg, I'm using 417 gallons/year.
If premium fuel is 25 cents/gallon more, then .25 x 417 = an extra $104/year. That's an extra 28 cents/day for premium fuel. So if I keep my car for say 5 years, using premium fuel would cost me an extra $520.

A lot of people avg 15-20k mi/yr for a DD. and even if you compare a low estimate of $520,
a mild 87 tune far exceeds using 93 w/o a tune and it only cost $275
you could use it forever, then when you sell your car you remove it and sell it on ebay for $150..
that's only $125 for unlimited miles

93 octane is just more refined.......so it burns better...I wouldnt waste my money on 93 w/o A tune/cold air...Gee i thought people buy a 6cyl for economy?????

Maybe a 120hp V6, but a 305hp V6? I bought my Stang for decent economy and decent power.

Seeing how +10hp only costs me a quarter a day, I wouldn't spend my $$ any other way!

You're the exception, most ppl avg 15-20k mi/yr for a DD.

Most Gov't. sources indicate the average person drives 15k a year, not 20k. If you sell a car that has accrued 20k a year, KBB, Edmunds, etc. all make you take a hit on the vehicle's price.


As far as a tune is concerned, your comment that a mild 87 tune makes noticeable hp over what using Premium fuel nets you is incorrect. If you watched the vid, Bama got:

• 252whp on a stock vehicle with 87 fuel
• 257.8whp on a stock vehicle with 93 fuel
• 265.8whp with a 93 Octane Tune

They didn't test an 87 tune in that vid, but it's obvious an 87 tune is only going to net you less than 260whp. That's the same as what using Premium Fuel alone gets you. See?

But to get back to your original complaint, no, it doesn't cost anyone "thosuands of dollars" more to use Premium Gas. Even if someone drove beyond the nationally recognized average and went 20,000k/year, after 4 years that would only amount to an extra $800.

Eight hundred dollars. Not thousands ...

I was comparing 87 w tune to 93 w/o tune. No matter how you cut it it's a lot cheaper to run 87 with a tune as opposed to 93 w/o.
Again $275 for a tune (even less if you sell it for when you're done w it) blows away even a LOW estimate of $520 (which will go up the longer you drive/keep the car over 50k mi)
A tune will give you better performance. It's not just horsepower, the throttle response alone is worth it, beside the hp, shifting and other parameters it improves.
As far as thousands, 3 of my last 4 Mustangs had over 150k miles when I sold them.. so I would've spent almost $5,000 extra on premium fuel

edit:
also.. insane may not have been an appropriate word. didn’t mean anything by it, should’ve said something like wasteful or inefficient. if you're happy with the difference that's all that matters..

lol seems "don't think" are the operative words here...

In my original post, I was comparing not making any physical changes to my car and instead putting in an extra 25 cents a day to get +10hp. No matter how you cut it, that's an incredible deal for no mechanical mods. Again, I need to point out that the $520 was for 4 YEARS at 25 cents difference in gas. But guess what, I was at the pumps today and the diff between Reg and Prem is only 20 cents. So 4 years of Prem is only an extra $83 year/$333 for 4 years. An even better deal than I originally thought!

As far as better shifting from a tune, I had the Hypertech tuner but specifically left shift firmness/rpm limit/rpm shift points stock. I like my car to shift smoothly, not as if the trans was in need of repair.

As far as thousands, I've been lucky enough to have owned 4 new cars over the last 7 years. Every car had about 7-9k on it when I traded it in, so to me (and I'm sure to a lot of other people as well) "thousands" doesn't apply.

Finally, I appreciate your admitting that "insane" was much too strong a word to use for this discussion. It takes a man to admit as much. In return, I would like to admit to ... ahh ... umm ... NOTHING!

I'll let you get the last word in, as I've said all that I wanted to say.

PEACE BRO, AND STAY SAFE. :thumbup:

Nice! I didn't know they carried vortech for the V6. Any issues with head gaskets or the 7.5 rear?

87 no problems that what they say to use

haven't had any issues with the head gasket and i replaced the open 7.5 with a 7.5 limited slip diff and 4.10 gears.

Low octane fuels can pre-detonate under the the stress of heat and combustion, igniting without a spark. Higher octane fuels burn slower,not better or faster or cleaner. If you don't advance the timing when using higher octane fuels it is possible (not likely) to cause damage to the engine. More likely running low octane fuel in an engine rated for a higher octane will cause damage. The only sensors related to this issue that I am aware of are knock sensors which will send a signal to compensate timing when an inferior fuel is used to prevent knocking. I would recommend running what the owner's manual says. Unless you got a tune

that's cool I was under the impression any 7.5 rear end wouldn't be able to handle the power. I have the ford racing trak-loc on mine, I'm guessing that's what you put on yours.

I had been looking at the stage II procharger kit but had read that it caused problems even at 8lbs. Glad to hear no problems!

Chief Gilly, I agree with you 100% on that, never put lower than recommended and only put higher if you have a tune.

 

[Y HELLO]

X-charged, 93 everyday, 104 race tune with Torco fuel additive. If your car isn't tuned for the higher octane I feel it's a waste of money, But try telling my wife that!

 

[ColdCougar]

SMH ... what a load of misinformation ... read THIS

The reason for Higher octane is higher compression ratios ... if you arent tuned for higher octane (trying to force MORE GAS INTO THE SAME COMPRESSION AREA) or have higher compression (flat top pistons, Forced induction etc) it wont do anything but take money out of your pocket !!!

with the procharger you wont have any problems as long as you dont go over 12 lbs. if you want to better get stage 2+ heads from SSM. im going to get a 10 lbs pulley, intercooler and use my HO tune insteady of the standard and get roughly 50 more hp

 

[breatle62]

Now my 78 c-10 beater truck 350 4bbl runs better on 93...valves clatter if irun anything less...its gotta idelbrock carb..so she likes fuel..

12 is ok as long as you get the stage 2+ heads from super six right?
