Engine 93 gas vs 89 gas

93 gas vs 89 gas

On a 00 rolla wit a vvti engine does anyone know if 93 gas actually is better then 89 for our cars?

All the pumps in PA or at least my area have 87,89,93 and sunoco's have 93 and 94 octane.

I put 93 in but idk if i should switch back to 93. I've been using shell's new V Power* 93 that supposedly cleans ur engine... Its also the cheapest 93 i can find. 2.03 per gallon.

So any comments

Yup, it built to use 89. Even tho you out in 93 for it, it still treats it as 89. So whats the point of wasting your money?? You should be happy you can use 89. I have to use 91 or higher, that means 93. I hate pumping gas.

I rock the 87 octane, and it's great.

:wstupid

lol, hey man, it's better than paying 20-30 cents more per gallon on stuff that won't make a bean of difference.

I wish I can find a place with 91. All the gas stations here only have 87, 89, and 93. I want to save some money.

You XRS guys HAVE to run high octane huh?

Yup. Has to be 91 or higher.

i would just stick w/ 87 or 89... imo 93 or 94 they burn up faster and use up faster than 87 or 89

Yea, you actually get lower gas mileage using higher octane gas.

Is that comparing your old corolla to your current one? Cuz I dunno if it'd be fair to say you burn more gas because of the octane level. Most high octane cars don't get good gas mileage anyways. They're overpowered sports or luxury cars.

lol i dunno how many times this question has been asked . but for any clear answer pm "killercocopuff"hehehehhee

Well, all i'm asking is if it's based on comparing stock figures for cars, one set for the low octane guys like corollas, then one for the high octane guys? Or if they just ran the two types at in the same car?

both my cars have to have high octane.... i'm not even sure the mr2 is getting high enough (91 is highest here)..... sucks especially since the mr2 only gets around 20mpg right now

i get shitty gas mileage right now. I get 210 on my tank i run it right b4 the light turns on or just as the light turns on i put more gas in. I put 93 gas. I guess i'll run 89 for a while

It applied to any cars. I wasnt comparing my current one and my old one. I read it somewhere that higher octane gas get less mileage than low octane gas.

I think you should get more than that. You shouldnt be too happy for what you are getting right now. 26 city and 30~31 highway is what I am getting right now in my XRS.

Of yea. That's right. It's pretty good then.

Actually 93 or 94 are HARDER to burn. With our not so high compression and not high rev engine, it's just a waste.

And probably faster, too.

I run 87 octane..works beautifully. If I plan on spraying, I run 93 to be extra-safe.

wow wat a waste of money i've been doin. I told my mom to put 93 in her new 05 rolla
guess i'll tell her to put 89 then
Its a non xrs btw

same here. probably cause my engine is getting old with over 208,000 miles on it. Well now I guess I'll just stay with regular cheapo gas now and save pennies also cause I put 93 once in a while thinking it makes my car perform better.

i run 87 in my gts.... ive never had an issue even up to 7800rpm..... i also get better gas mileage and more power with 87 than with 91

holy shit!!!
i only got 44,000!!!
I think my intake is screwing sometin up. But on the other hand in the summer time b4 my intake i only had 250 per tank wit easy drivin. City only, only up to about 45 mph i drove

well everytime I fill up I reset the trip meter. Everytime I get half empty I already drove around 150 miles. Most of the time its around 10 or so miles over. Then the lower half my mileage doesn't keep going for another 150. Everytime I drive it from full till the light is on and needle is on the empty line I don't even get close to 300. My most I can remember is like 260. Must be because of the minor bolt ons I installed, my leaking exhaust system and faulty O2 sensor.

I usually don't reset my trip, so I never know how much i'm getting, but when I first had my car I did do it...I usually got around 325-350 on one tank of gas.

93 for me.

yeh same for me, the first half of the tank goes great, i get like 150 miles on it or so, but the second half, the needle drops so fast!!!
