87 all the way. I get angry with 89 .

 

Lowest stuff I can find, in any of my RX-7s

 

did you ever use race gas???? if so you would no it smells like candy yes or no???it is the same thing for 86 race gas!!!!!!!!that is what i was saying

 

i use 93 in my 88 n/a. i get good power and it does feel smoother on all gears than putting 87 or 89. i still need to lean the a/f mixture though but i do get about 17-19 mpg city.

 

i wish i could find anything below 87 cuz i would run that but since thats all i can find thats what i use.

 

Only time I ever drank octane was when I was siphoning gas...

 

where can you find 85 octane?

 

In high elevation states. I live at 6800 feet above sea level. Typical rule of thing I have read about is you can reduce octane by 1 pt for every 1,000 foot gain in altitude. This rule of course only applies to normally aspirated unmodded engines.

 

I use 87 in my TII....every once in a while I like to go 91 but that's rare...

 

^ same...87 TII running 87 octane...it told me in the manual that it was designed to use 87...that was enough proof for me that its ok to use 87.

 

That only works if its stock, though.

 

87, the cars are so low compression higher octane doesnt really do much

 

The only way I can figure out this one is that your car's timing is advanced of the stock setting. But if that were the case, then you'd be detonating on 87 octane.

Consequently, I have to call baloney on your statement.

Another quick comment, its amazing how many people have accelerometers and dynamometers in stalled in their asses. The only valid way to test a power improving theory is to put it on a dyno and take a reading or take to to a 1/4 mile track.

There was another poster in another thread who stated he felt a 1 HP increase by doing something different with his car. I almost died of laughter.

 

Wow, thats pretty f'ing funny.

 

I've been using 93, but recently put in 89 and it hasn't exploded, so I think I'll stick with 89.

 

Yo where is teh gas station? I looked all over for it and I can't find it, and it's not in teh phone book.

 

I've never put anything less than 91 in my Turbo II. I would like a higher octane level, but it's the highest I can find around here. I've heard rumors of 94 somewhere, but I haven't found it yet.

 

i'd be using 110 octane at the pump here since its 3.75 a gallon, but i dont wanna hurt my AEM wideband o2 sensor

 

94 octane , but with new rebuild I will go with 91 for the first 1500 km of break in. Then ill decided if i want 94 or 91 .

 

91 or when i can afford it again 110 in my GTUsT
87 in fiancee's GTUs

 

Lucky bastards with 110.

 

why so much octane in a stock turbo?

mine didnt ping at a bar with 91 and thats prob more than what you boost?

 

87

 

98 in my '86 TII. That's the highest pump fuel available in Australia. We don't have 87 octane, the lowest is 91 I think.

 

^ i hate you!!! the highest we have here is 90 at the pump

...unless they are reated differently....
