Celica Forums General Discussion General 1989 Gas In a GTS

I hate Spending money on gas (we all do), and the way gas prices are today.. im really tempted to just press the 89 button instead of the 91. I was just curious on how bad this is for your car, and if anyone on this site actually does this. I doubt im going to do it, but i just wanted to hear your guy's input.

I punch that 89 button all the time!...Get ur self one of those gas credit cards!...

91 everytime, cept for the first time I filled it I tossed regular in by accident not knowing our compression ratio is through the roof.

Don't do it to your car.

It's bad on the sensors, injectors, and if you rev it up, it'll knock and ping like crazy.

Damn...I always use 87 gas...Shoudl i be using higher? I dont race or anyting but i red line first and second now and then...i thought using 87 was fine...

always use 91 on the gts..don't use n e thing lower. it's bad for your engine.

are you serious...

you're a stupid shit if you put shitty 89 octane in a GTS, read you manual fool, hope your engine runs itself into the ground.

i use 93, used to use 94 all the time untill sunoco stopped having it

dude it says on the little gasoline door, Premium Fuel only! Dont be a cheapskate and a fool and put 89 octane in the celica! My dealer told me that your motor will knock and ping like crazy! And it ruins the total life of your engine. Anyways putting 91 octane is a good thing, knowing that your putting premium in your celi is just sexy Also from what the dealer told is that our motors require 91 gas is because our GTS engines are high Performance engines. Anyways I would not want my GTS to have cheap gas and have my engine knock! no way! jose!! Stick with 91 octane man! I know its expensive but worth it in the long run of the life of your car

damn man thats a mean thing to say... maybe he didnt know lol.. heh

91 octane since day one

yuuuuuuuuuuuuuuuuuuup fa sho!!!

93 from day one

or 94 when I'm around a sunoco

Dont flame people... but what about a GT?

^^ it says on there

just regular

Does anybody actually have the manual out? I bet 89 is just fine for the GTS 11.5 to 1 aint that high.

I just give what my baby asks...for all I see is "Premium Unleaded Only", inside her fuel lid be.

i have a GT i give it middle grade

...is 89 premium for you from where you from!?!?!

if not, 91 (US/CANADA) is the lowest you can go on GTS...

EDIT: and 11.5:1 is very high already...

I only use premium.

Well Technically 89 is considered Premium Fuel

I have a GT shoudl i be puttin higher than 87 in it or does it matter?

No 87 is fine in a GT from what i heard

Premium would be 91 and above...has anybody try the 98, 99, or even the 100 octane yet???

Well in PA 89 is premium and 92, 93, 94 is SUPER

wow, you guys are in the woods...

A friend of mine have a GTS, He blow his motor at 130 000KM (i think in miles it's ~ 81 000)

I was putting regulard fuel in it and some day the motor started to ping more and more and bang

I think 89 is considered a "midgrade" fuel. The real reason its available is for people supposed to be using 87 and finding they're getting some ping. I'd never step down to something below the recommended octane. You could use something with a little higher octane, maybe 93-94, but too high can be dangerous for the engine too.

The octane level is determined by Toyota & it will be in the manual. Nothing higher that what they state is required. DOES NO ONE HAVE A MANUAL?

^^^^ 91 octane is REQUIRED

89 won't work in an engine with such high compression, just like shifting without the clutch won't work in a car with such weak cables.

It says 91 in the manual i think

i use 89 in my GT all the time

87 for the GT, though IMO i feel a difference with 91.

if only gas weren't so expensive...

just use 91 man its bad for ur engine, and if you think its pricy you should of never got a GTS. you should of known the expenses you were getting into, good luck homie and if you use something low and ur engine blows let me know so i can say "I TOLD YOU SO!!!!"

ok, i dont really understand. for a regular driver, if you put 91 octane instead of putting 87, ur gonna spend around $100 more on gas every year. 100$ aint nothing nowadays, its better to spend 100 extra for gas then repairing few thousands dollar parts on ur car. plus the gts recommends 91, if you put lower one, it will either knock or damage in other way. it will perform normal at 91, but if you put better octane than 91, it will even perform better. so use 91 minimum and stay out of trouble that will come later on if you put 87

What does the manual say?

Does anybody have a manual?

The octane required by the engine is NOT a matter of opinion. It is predetermined by the manufacturer.

^^^ Are you BLIND?

91 octane is REQUIRED, I already said that

Toyota says: "I think it takes 91" ...

I already posted that PREMIUM FUEL IS REQUIRED.

Do I have to post a bunch of websites for you to listem to me?

I am telling you the manual say 91

Is that what the manual says or is that what you are saying?

Too many people have "FACTS".

THE MANUAL SAYS 91 OCTANE

That's what the manual, fuel door, toyota, Car and Driver, etc, etc, etc, etc, etc says.

Premium fuel is REQUIRED.

If your referring to my previous post, I own a GT. Minimum octane is 87.

All I was saying is that when I put 91 in, I notice a little better Performance (less lag from a start with the a/c on). Obviously, if you own a GTS and you're putting in anything less than 91, you're asking for trouble.

If you weren't referring to my post, ignore this.

You think ...
