89 safe compare to 91 Octane?

[GullyBoy21]

I just found out that i should be pumping 91 octane on this car(boom01). i've been putting 87 (regular) for the past year(braindead. But all i see in gas stations in Long Island NY is 87 89 93. If i pump 89 instead of 91 would i still get the same positive results i want? what effing stations have 91 octane?

What? How did you own this car for a year not knowing that? It says it in the manual, the quick guide, and right on the fuel door! Your car actually ran decent for a year with 87? Use the 93.

The car ran perfect... seriously... For some reason i got it stuck in my head that 87 was fine, and since my car felt fine i didn't give it a second thought. so what should i do?

NJ has 91

No offense but wow!

 

[lestat13]

Use the 93. If nothing else, think of it as an investment. The higher the octane, the better high performance vehicles run anyway.

 

[GullyBoy21]

Ooh Its okay... since you said no offense i wont take it as an insult...
The can ran great. I was getting 300 miles with a full tank.(city/highway).

 

[Sveivo]

Well, at least you weren't trying to save money like some of the CX-7 guys

O0H MAN... this is going to suck with these gas prices now... lol i can't wait too see if theres a difference in power.

I guess the ECU is smart enough to adjust, but I would use 91 or better.

Well, it's only like a 5% difference in price on average between Premium and the other grades.

hahhahaha i useto have that game! i beat it... lol that sounds a litle perverted. wow Sega Genesis... memories.

 

[GullyBoy21]

yeah i love this car...(burnout)

I think that Mazda meant to say 91 octane or higher. Lots of places only have 93.

The higher the octane, the moar resistant to pre-ignition caused by high compression (higher temp). Remember, the moar you compress a gas, the higher the temperature of that gas gets. This is how diesels run, from compression induced ignition.

 

[hilmar2k]

The manual say use a minimum of 91 octane. The reason it says "minimum" is because you cannot get 93 everywhere in the country. Here in NY, 93 is ubiquitous, so that is what I use and recommend you use.

 

[m5rMS3]

I make it a point to go to gas stations that sell 93 instead of 91. It is usually the same price.

 

[neox.286]

yea out here in cali you cant find 93 really, theres a few spots but not that many

use 93, I wish I could =(


I dont see why they dont either....Cali is all about 'emissions regulation', isnt 93 is supposed to burn cleaner than 87?

 

[FrequentFlyer]

No. Octane rating has nothing to do with burning cleaner. In fact, running high octane gas in a car that wasn't tuned for it will burn slower and be less efficient. More octane just resists predetonation in higher performance engines that have high compression, forced induction and/or are tuned with aggressive fuel/timing maps.
