Type of gas?
 

I just got a 1992 Talon ESI and im wondering what kinda octane gas is used for these cars. My friend says Premium... but that is way too expensive...

Re: Type of gas?
 

You don't have to use premium in a ESI I would think. Regular unleaded should be just fine for your car especially since it isn't boosted. The higher the octane gas the slower it burns so you can compress it more. Thats why turbo cars need the higher octane gas.

If you need to run premium that is news to me.

Just for reference, I would suggest telling us a little more about you and your car. If it has any mods, future mods, ect. I would move this to a tech section but I will let this serve as your introduction thread as well.

Re: Type of gas?
 

I definitly agree with you buddy.

On another note. Why in the hell would you think youd need anything other than premium. In my 92 *turbo* it says premium right on the cluster.. Use regular ass 87 octane unless you feel the need to waste more money. Or put a T engine in and burn out some goo' ol c16, it smellllllllllllllls So good!... ::wink::

Ok Josh, your post limit is up for one day. Go to bed now.

Well first off I live in Vancouver, WA. I am 19 in may. I just got the talon like 4 days ago. Only mods on it, is that it has bigger wheels/tires, it is lowered, has an alarm, shitty CD player, and a nice muffler... and I need to fix.. the headlights... back latch.. and right blinker cover.. Which I am gonna need help fixing.

I plan on getting a new intake for it.. but i dunno what to get. And new brakes when i get the chance.

Re: Type of gas?
 

Craig is right (oh shit did I just say that!!!). Premium in your car will make it run better and you might see a little better mpg out of it. But IMHO, it isn't worth the extra money you would be spending on it right now. The engine that you have does not demand premium. We all have to run premium because of our turbos.

Although. it is good every now and again to run a tank of premium just to let your engine know you still love it.

Re: Type of gas?
 

haha yeah. I love it..

Re: Type of gas?
 

haha erik, I suppose it is still a 4g63.. deserves love every ONCE in awhile. I sure didnt like my 1.8 tho, Its lucky it didnt get rice in the tank.

Dont worry, I went to bed. It got a little late and I was a little hostile! I promise.. ( maybe ) I wont be like that tonight! i <3 you! haha

Assuming equal quality of gasoline, he will get better performance and mileage from 87-octane fuel since that is what his engine/ECU was designed for. The ECU will not add more timing as the gasoline octane increases; which is the only way he would get better mileage and power from his NT engine. Again, this is assuming equal quality is the grades of gasoline, which should stand true using a decent brand such as Chevron, Sunoco, BP/ Amoco, etc.

Re: Type of gas?
 

I disagree. If your car is designed to run 87 octane then thats what you should run. I think that running a higher octance gas would hurt performance if its not designed to run with it.

And that goes right with what Chris said, assuming the qualities are equal of course. I have always wondered why you see N/A cars putting 110 in their tanks at the tracks and thinking its helping them? Is it? Or does it just smell faster?

It’s a non turbo, get full coverage ins, and put sugar in the gas, than collect the money (Vandalism), then get a turbo and run 92 oct.

Re: Type of gas?
 

Sugar won't do anything but clog the filter...urban myth.

Re: Type of gas?
 

Owned! But if the filter becomes pluged while the car is running, as it should, it could still destroy the motor. Just think of a Talon doing a WOT pull and a gorilla pinching off the fuel line right in the middle.

Re: Type of gas?
 

No, no, no, put sugar in the exhaust and a banana in the gas tank...

Seriously though, there's really no reason on a stock non-boosted car to run anything higher than 87, unless it is specified by the manufacturer. Now, tear down the block, run 11.5:1 pistons, rev to 11k, cams, & whatnot, ...then you might want to think about higher octane, but only if the tune in place demands it.

Re: Type of gas?
 

How about 11:1 compression revving to 9k with a double shot of VTEC at 6k? :D

Re: Type of gas?
 

Someone poured a lot of sugar/syrup in my gas tank. Fucked up my car pretty good, so no it is not just an urban myth. My engine locked and wouldn't turn over as the needles were stuck open in the carb and fuel was pouring into the cylinders. Lucky I didn't bend any rods. Had to remove the gas tank and complete fuel system and wash it with hot water. The bowls of the carburator had an inch of syrup type mixture in them.

Sounds torqueless to me! ;)

Re: Type of gas?
 

mmm.... caramel.

Re: Type of gas?
 

yeah, when I first took the carburator apart I scooped some of the gooey gunk out with a screwdriver and lit it on fire. Smelled like we were roasting marshmellows. My entire intake manifold had a hard candy coating on the inside!

Re: Type of gas?
 

Exactly what I was getting at. That motor was designed for performance. When Honda was designing the S2000, it was originally intended to have 215-220hp and weigh xxxx lbs. When they got the road-version ready, it weighed about 150-200 lbs more than they thought it was going to. They had a target power-to-weight ration in mind, so they simply upped the anti and did whatever they could to get more out of the engine: i.e. less conservative tune, higher rev-limit, etc. Your average non-turbo car, (i.e. the ESI mentioned above) is not going to have such an aggressive tune on it from the factory, and will not care as much about higher octane gas.

On the flip side of this whole discussion, I have a friend that used to have a Volvo 850R (turbo). He always put 87 octane in the tank because it was cheaper & he claimed he didn't notice any difference--of course, the car was un-modified, and it was an automatic (but nice!).

Side note: Does the s2000 require premium (i.e. per manufacturer's spec)?

Re: Type of gas?
 

91+ octane.

Re: Type of gas?
 

Melts in your intake manifold, not in your hand...

Re: Type of gas?
 

That’s what I thought too, until I did a some work for the body shop, in witch someone put sugar / syrup mix in the fuel tank. The guy was luck though, I only had to replace the fuel pump, filter and injectors (V8), it ran ok, but it ran.
So I have your urban myth swinging. j/k

Re: Type of gas?
 

Hmmm, maybe it depends on what type of filter? I saw this on that Mythbusters show and they never had any problems except a clogged filter in their testing.

Re: Type of gas?
 

N/A cars put in higher octane due to high compression and nitrous, not because it smells good, dumbass. How the fuel burns and the amount of time it takes to burn are a FEW properties and advantages/disadvantages of running 'higher' octane gasoline.
That being said, if the car is designed to run on 87, please burn 87.. adding 'extra' don't do shit but burn a hole in your pocket. The urban myths of 'liking your car' so putting in 'mid grade' or a tank of 'premium' just decreases the power of the car, under most circumstances. However, not all grades of gasoline are equal, and just because it has a higher 'octane' rating, doesn't mean its better. Doing some research into motor octane versus research octane of the specific 'race gas' you are going to run, can help 10 fold when it comes to tuning.
Welcome to the board Jcline, your lucky to get 3 tech posts per help thread, but you will have a 2 page thread within a week..

Re: Type of gas?
 

I saw that one too I love that show. But sometimes they don’t always use the right process , like the time they shot a frozen chicken at a plane windshield , only later on come to find out that the plane didn’t have safety glass or what ever, like in a commercial air craft.

Re: Type of gas?
 

Really, god I have been misinformed all this time but thanks Swanny for correcting me:rolleyes:. But when did I ever say anything about high compression. You just said the exact same thing I said minus the ricer JOKE at the end. Dumbass.:rolleyes:

Re: Type of gas?
 

Are you telling me you haven't seen the honda boys running race gas? V-tach luv's it, yo! Dumbass ;)

Most people have a misconception about race gas, they think they will add a bunch of power by putting 110 in a regular car. That is BS. That is what Craig was talking about.
