Octane Levels for 4age Ae92

[88corollaGTS]

This may be a stupid question but here goes anyways. :grin: I ran into a guy in town here with the identical GT-s to mine excet his was a 1990. He was telling my that I should only be running 91 or higher octane in my GT-s. He said that is what it says right from the owners manual?? Is this correct?? I have just been running 87-89, should I be running higher octane?? The car seemes to run fine off it but if it was designed to run on premium then I will start feeding her premium.

well your as been runing on 87-89 for 14 years!!!!is there a problem ?.....no!

it will be a little cleaner inside the motor
but nothing to rush to the nearest station to fill up with 91- 92 octane!!

my car was runing from the day 1 with high octane gas.

if i put 87 or 89 in it starts pigning like
hell. when i take of my key from the ignition it still runs !!!!

thats the reason wy i put high octane.

i dont know in ontario but here in quebec we can have 94 octane at petro canada.

put with that an octane booster and you can actualy notice a bit more response from the car.

sure if you dont mind the extra cost it wont hurt.

Yeah we can get 94 at Sunoco in Ontario. I don't know what the Petro canadas premium is. SO I guess there isn't a whole lot of use switching now except for maybe psychological reasoning. :grin:

I'm not talking about the 4AGE, mine is the 4AFE but I know that if your run higher octane gas your performance will slightly increase! But I've never heard of an older car that has to run on 91 or higher octane! When I first bought mine it was running on 87 octane and then after changing my engine I started putting 91 Octane and synthetic oil in it...

mid 1989 toyota changed the engine in the ae92 corolla gts to a high compression model that required high octane gasoline.

his is a 1990, hence after 1989.

yours is a 1988, before 1989

you can run 87 octane, he cannot.

hi comp = higher octane gas needed

so yes, you'd need the more pricey gas
