I went to feed the pony today and AFTER I pre-paid, I noticed all three pumps had a sticker with 87 over the octane choices(Its 86, 88, 91 here..strange, I know). Many of the gas stations across the city have stopped carrying Premium fuel, and some even Plus! A while ago when gas was a good $4.25 a gallon for 91 octane, a particular gas station had their 91 on sale for $3.60. I filled up immediately, then sent a mass text to everyone I know who uses Premium, and even those who don't. Is this happening around the country, too? The only Regular gas that has ever been in the Mustang is the full tank it came with!

There's no real possibility ALL Premium will be gone, considering there are vehicles on the road which require it. Its just upsetting and annoying. What do you guys think? I'm sure there are plenty of you out there who use 91+ octane, even if your vehicle doesn't require it.

 

That station was either out of the others, who has decided to only sell 87 now. They will NOT get rid of the higher octane fuels so don't worry. You also don't need 91 or 93 with a stock tune on your car.

 

up here in Houston it is almost impossible to get gas since Ike came through. Looks like that your feeling the effects all the way up in el paso.

 

weird haven't seen anything like that around here. Gas is still 3.51-3.55 hasn't budged. I wouldn't put premium in your stang unless you have a specific tune for it. Doesn't have any benefits and could actually harm the engine after a real long time. Only benefit is a little quicker acceleration by the dent in the wallet.. or purse I suppose haha. Gotta change the saying up a bit

 

We still have 91 here.

 

hell theres a gas station up from my work I saw at lunch that is only selling premium and is out of everything else!

 

Thats sucky to think of all the money you've wasted. Give it 87 anyway, it's what the stock tune is designed for.

 

Stations around here have been getting rid of 88 and 91 octane for months now. The only places you can find it is at the larger chains such as Chevron.

How am I harming my motor? Manual specifically calls for 87 octane. It also calls for no higher than 100 octane because at that point most fuel sold is leaded and oxygenated, which will burn up your o2 sensors. Higher octane fuel also burns more efficiently, therefore making it cleaner for the system. I see the couple extra dollars I throw in my tank every week as an investment, not a loss. If I were worried about gas money I wouldn't be driving a V8 of ANY sort.

Its like asking, why use Mobil1 oil when you can just use Motorcraft for cheaper if your motor is stock?

 

It's not that simple.

 

but I thought Ford and Technology didn't work well with one another so therefore it should be simple.... or am i missing something?

 

There's nothing technologically advanced about an inefficient internal combustion engine

 

you mean...
1) suck
2) squeeze
3) bang
4)blow

 

That sounds naughty.

 

 

higher octane fuel is not more efficient and does not burn cleaner. All octane does is control detonation, that's it. Any difference you feel is in your head. Does it hurt the motor no it doesn't, but higher octane fuel actually burns slower then lower octane fuel. So save your money and use regular 87 until its tuned for higher octane with more timing etc..

Oils a difference ball game, if you start that up were gonna have people jumping in with crazy oil change intervals etc..

 

personally i like mustangs....or atleast how simple they are... for noobs like me it makes life easier!
