Okay so I'm picking up a 95 civ coupe thats turboed at 6 psi, the guy has it running on 91 but i'm a student so i was wondering if i could run it on 87. Thanks .

 

Run premium if you want it to last. If you go with **** water it "might" run fine as long as you drive normally, but is it really worth it to take that risk?

 

Thanks for the reply, I guess its definitely worth the 5 dollars extra every fill to save your engine.

 

93, all the time everytime

 

how does it matter? I don't see...the 95 engine was designed to run on 87, how does the turbo affect it?

 

is the engine itself stock or modified? if internals are stock, higher octane = knock reduction, b/c of high performance i say you just be smart about it and employ the high octane. if you wanna play with the big boys, make sure you fit in all around :-D

higher octane less chance of detonation
detonation is expensive on a boosted car

ditto....im runnin 93 all the time.....im running 6-8lbs of boost and wouldnt dare runnin anything less...

 

Wow, that blows...and w/ gas prices the way they are, to think I was thinking of going turbo, what a bad idea :-\

 

It's an extra $3 max @ each fill up. Stay out of boost and it'll last longer.

 

you guys are lucky at the most your paying a little over 3 dollars for a gallon up here in saskatchewan i'm paying 118 a litre!

 

about gas...how much are you guys paying per gallon now? since the price is goin up again. where i live, its about $3.49 per gallon for the lowest one.

 

Depends what the car was tuned to. Most likely it's tuned for 91 octane since that's what he's running. I wouldn't go less unless you want it retuned...

 

mid grade is running 3.31 - 3.45 right now.

When I can I just take my mom's costco card and get the 91 octane for a couple cents cheaper than chevron 89

 

stick with 91 octane, or your motor will feel the wrath of low octane.

 

Sorry to thread jack...

But if I have a car tuned on 91, is it safe to go up? I figure tune 91, and then I can use 91 or 93 depending on what the gas station has.

 

Perfectly safe.

 

don't cheap out, get good gas

 

$2.98 for 93 in bama

 

i dont have turbo in my B16, but I always use 91 (the highest here in Quebec). Im a student too, but 3 bucks more per fill wont kill you.

Thats half the price of a pint of beer anyways.

 

gas here in NC is $2.98 for premium and I am going boost soon on my Z6. I fill up every 200 miles though and it costs me $23 on mid grade (10.7:1 CR on my donor motor) so its so-so but once i go boost i know i will be racing my own shadow all the time. lol

 

here's the deal....

As it is, run 91 because it is safer

When you tune it CORRECTLY then you can run 89 if you set it up that way
but the cost of tuning probably equals the extra money you'll be paying for 91 for a year

 

If you have enough money to get a turbo car then you have enough money to get premium.
