What grade of gas do you put in your Coupe?

[elderboy02]

Do you use 87, 89, or 92. I have been using 89.

If you have a 3.5 you are supposed to use 92 octane I beleive.I have a 2.5 and use 87 octane, I think that 89 is a waste of money for the 2.5, unless you live in a high altitude location, it's really not necessary

[Chiefster]

This would of probabaly been a good poll question.

89

[phobs]

If you have a 3.5 use premium, if you have a 2.5 use regular. /thread

[boystar22]

I've only put 87 in my 2.5 and I smile every time I do (which is far less often). The Audi I use to have had to get 93 every 4 days, thankfully now I'm running $.30 cheaper a gallon and before I was laid off I still got a week and a half out of a tank. Being jobless has put me at a month or more on a tank, which is sweet in a good/bad way lol.

I don't have enough fingers or toes to count how many times we have had a thread for this.

Use what is recommended.

RTFM < bottom line

You got it

Now for all the lets discuss why we use what grade of gas that we use in our cars.

[Mr.Coupe]

I have to use Premium gas on my car because it's FI . Other then that I have always used Premium on all my cars.

94 octane or V , i get better gas mileage and it contains no ethanol

Apparently, reading the owner's manual is optional.

[Desire1314]

where the hell you get 94 octane? most gas stations here offer 91 as highest. shell and sinclair are the only ones who offer 93.

Sunoco

[LinkNuc]

93 when filling at Sheetz or 94 if I go to Sunoco.

[2008AltiCoupeDan]

sunocos by me r absolute crap w/ "contains 10% ethanol"

after my intake and using 87 my car sorta bogged starting into first- i use 89 all the way now. cleaner in the long run, and a little better mileage 1-2 miles per gallon than 87- but its noticable- i watch my gauge like its a religion lol

[marlin29311]

Blah blah blah...I hate this thread and every one before it.

87 for the 2.5

91+ for the 3.5

/thread. No more discussion. Anything over 87 for the 2.5 is a waste of money, and the 3.5 can run on 87 at a lower performance level. That's it, that's the science, and the truth. No disputes.

[Ferguson]

Amen.

[JIBRIL4life]

a better questin would be how much did you pay for gas today!!!!

93.8 cents/L

and 87 octane at Petro Canada.

useless for the americans but useful for the canucks!!!!

[Ferguson]

106.9 per litre for 91 at Petro Can. 40 bucks and I got a little over half a tank.

[Ranga14]

To prevent new threads like this popping up, maybe making it a sticky???

And I use 93 Supreme from Exxon.

[DaCoupe]

petro canada used to be FTW, until i found out they have more than 10% ethanol in all their fuel. Ive been using shell ever since i read that report about the best and worst places to fill up. Shell was number 1 especially now that theyre using nitrogen in their gases that clean out engine gunk and of course 0 ethanol, after that was Sunco because they have 94 octance, then Esso, then petro last. I was surprised to see petro was worse than esso. Ever since i switched from petro 91 to shell 91, ive noticed a 3 -L/100km difference and a better range.

[LinkNuc]

Damn 2.89 Gallon out here or 76 c per liter...

[maxentropy]

I only use 87 in my 3.5 (lower performance suppossedly) Although somehow I managed to get 1:06 (first and only run) on the autocross at Carlisle this past year.

I live in PA and it's way too damn expensive to fill up with 93 all the time. It's always approx. 20-30 cents more than 87.

$2.69 for 87$3.02 for 93

[DAAN.]

Sticky this up

87 / we love our altimas, but this is not a high performance car, so you can live with 87

Daan, you have a 3.5, right? At 275 HP, it IS a high-performance engine. Nissan does not (last time I checked) own any fuel companies and they recommend 91 octane. Not only does the higher octane fuel give the engine its best performance but it also keeps the engine cleaner of deposits. In the long term, 91 will maintain proper engine performance and reduce potential, and costly, repair bills as the car ages.

It's a fact that performance suffers on 87. A fact I have even proved myself.

Why do you keep insisting that 87 is acceptable? Just because a relatively new car runs on it?
