for an fc what grade gas is best

 

on my NA i use 87....on my t2 is use 91 or higher...

 

could you be any more vauge?

N/A, go with 87 octane

turbo, go with 93 octane if you can get it near you, some people only have 91 or 92 near them.

 

on my 88 Na I use 87 octane.

 

+1, simple as that. What a stupid thread.

 

oh dont forget unleaded gas

 

The $3.37 gas.

 

yup....how many people know of the search option??

 

lol...i dont think cali here has that low of a price on gas....91 octane is close to $4 a gallon...

 

Sunoco Oh noess I opened another can of worms!!! Yeah, stock car 87, modded then 91 or better. No difference in performance just helps lesson the chance of detonation with higher octane.

 

actually ive heard on NA cars IF you can find 85, it makes a little more power because it burns quicker/more throughly. but odds are, you wont see it.

 

My dad will only go to a Sunoco gas station, he feel that they dont cheap out on gas like others.(Some places use less octance gas saying its a higher octance,seen it in the news before)

 

mobil/exxon 93 and 100 octane at pump!

 

sunoco here has 93 and 94. The station down a was from my has 100. but ive heard that the 94 sunoco is questionable.

i use shell 93 normally unless i want to spend the money on the 100. or go to Chardon Oil and fill up with Cam2 or c16 at the pump

 

wow...100! wonder how much does it cost??

 

Wow, that sucks. Regular is 3.15 here today.....on the rise again. Must be prepping for the next hurricane.

 

I hear some people saying they run 87 in their TII, and that it makes more power. Is it worth the risk of detonation?

 

the owners manual does say to use 87 octane. but...eh...i wouldnt.

 

no, I dont even worry about the extra .20 it costs per gallon to get premium. I get 10 gallons at most at a time, so that means if I got regular I would only be saving $2, no way is that worth the risk of grenading the engine.

 

^+1

 

ive never even heard of 87 octane the lowest we have here is 91 but i usually use 98 or 100 or 105

 

Well aren't you special! j/p

We would be paying a fortune over here for 105 at the pump...anyways, I have heard running 87 in TII's too. That's what I currently run with no problems. Should I be putting 91 in it, or is it really up to the individual?

 

That's because your gas is rated differently from US gas. Your 91 is equivalent to our 87, etc.

 

How much is a gallon of gas in Australia?

 

Both the TII and non-turbo FC models are rated for a minimum of 87 (R+M)/2 with no more than 10% ethanol. If your engine is poorly tuned, very worn, or running a lot of boost, then use a higher octane rating as required to stop any knocking.

There is no risk of grenading the engine with 87 (R+M)/2 if the engine is in good shape, tuned properly, and not running a lot of boost.
