aiya, just suck em up and pay the price for premium. I used to complain too but I cut down on other things i could live without ($20 dinner at a restaurant, weekly dvds, snacks, etc.) Plus it helps to have cynthia pay half of what I pay cuz I drive her around.

 

yup yup...i wouldn't try running something that "MAY" be bad for your car. even if it's not noticable...better safe than sorry

 

dont even try it, the higher the engine compression the higher octane gas u gotta buy. whats the gt-s, like 10-12 psi? since the extra additives helps keep the gas cool enough so that it can be properly ignited by the spark plug instead of exploding inside form the heat caused by high compression. the explosion is also this so called "knocking" sound that u hear about, it also damages the engine.

god i hate thermodynamics

 

I was curious if anyone else with a GT-S has ever tried to put in 89 octane(mid-grade) gas in their car. If you does it run ok? or was there engine knock?

Just curious since gas prices have been going NUTZ.

i did when i first got my car bc the stupid sales guy told me i could put in regular. so instead i put in the middle one and my engine did make clicking noises and rattling. sounded like there were rocks in my engine. better not do it.

 

What about a Gt with midgrade? i was wondering if this helps improve gas milege or gets me a little more umph for my money?

not really, they did a study and said that if u use 87, then switch to 89 or 91~92 wont make a noticeable difference, the fuel just burns cleaner so ur engine stays slightly cleaner

 

cool thanks for the info.

: im probably going to laugh at you forever about this... or atleast everytimg you bring it up...

 

it's not my fault! the stupid sales guy told me that. had to be chinese. at least clint told me.. imagine if no one even stopped to tell me that i was putting in the wrong gas. my car would be dead =(

If your compression is only 10-12 psi I wouldn't be worried about what grade of gas you put in it. The car would be broken. The compression ratio on the GT-S in 11.5-1. Anything less than 92 and the car isn't to happy. It'll run but not well because the ECU is compensating for the lower octane and retarding the timing.

It's a good thing you never did hit lift when you were running the lower octane. I'd hate to think what would have happened. :AF:
