With the gas price lingering around 2.70 dollars/gallon these days, I'm tempted to get off 93 octane and go with 90 or 89. My engine being bone stock, I don't think this will hurt my car but just wanted to ask you guys before. Anybody doing this?

 

thats a good question
i bet lots of people are thinking on doing the same thing with these gas prices and i bet some have already done so
but all i have to say is that Premium gas is recommended for our cars for a reason

 

i wouldn't recommend it. You're only saving what....$0.10 per gallen? So that in turn comes out to $1.50 per fill up on average? I'd just pay the extra $1.50 so you don't have to worry about anything.

BTW: I drove by a gas station today.... $2.80 at my local chevron. I knew i should have kept my beater car....

 

yeah, i had 0 gas today, and i'm sittin there at the pump thinkin, lol. i went with 93. i'm sure for the past 12 years, the guy used 89, but, i always use 93, lol. total came to 45 bucks.

 

^^ HAHAHA. True. Now that the story unfolds like this, this thread sounds like a repost.

Everytime I feel her up I feel like i've been jacked. 46 dollars? And I get only 14-15 mpg due to all the city driving

 

I was thinking of the same question today. When i passed by the gas station, it was $2.71 for 91 octane (highest one in socal) i was like WTF. I thought about using 89 octane but then again, I will just be saving up around .10 cents a gallon and thats just chump change that you can find on the ground. So I guess I will stick to 91 octane. But one thing to say.. Gas prices are Ridiculous!

Wow, I gotta stop whining about our $2.44 premium prices, that $2.70+ is crazy!! Oh yea, just run the good stuff, give your car a tune-up (especially the ignition system, and maybe the O2 sensors), keep your tire pressures in check, and go easy on the gas pedal

 

right exactly. i think it would have saved me just under 4 bucks to use 89 over 93. so i said hell, i'm already spending over 40 bucks, why not spend 44 instead of 41, lol.

on a better note, i heard that gas prices will be down to under 2 bucks a gallon by july 4th. at least around chicago where i am.

 

REALLY? What's your source?

 

Man i hope this will happen in SoCal. I just found out that this other 76 gas station right next to a freeway is $2.89. Now thats some BS.

 

someone with a portable scanner should run lower octane gas and plug in the scanner and watch the engine timing while driving(have an assistant watch) , and look for a diffrence, if i had one i would try it to see how much the ecu would retard the timing and such....

 

My mechanic has told me that these cars have a computer that modifies the timing a small amount to adjust for the differences in octane. I always fill up when my tank when it reaches half empty/full.
So, he has advised me to fill up with the 91 octane every other fill up, 93 octane the other times. (remember, I always fill up at half empty). This saves a little money and, so far, has had no ill effects.

 

it was either the news on TV or AOL news or something. they said average gas by memorial day would be 2.50, but by the 4th of july, average will be under 2 bucks. hope the news is right.

 

Trust me, it is going to keep on going up.


With summer rolling around the corner you can only expect for prices to rise.


The octane of fuel can be a difference, if you have used it since you bought the car. (assuming brand new) and have followed up with routine maintance. If you guys ever get the chance, pull the intake and take a look, if it is sparkling clean well then giddy-up. If there is carbon build up. CLEAN IT!!!!


That will save you at the pump.

And seriously, until we are paying around 7 dollars per gallon (England) then we shouldn't worry.

Thank God I still have my old 84 Corolla!!! (get's 36 mpg)

Cheers!

Damn ya'll got it bad, I just paid $2.37 per gallon for premuim today here in Northern Virginia, it cost me $38 to fill-er-up.
