whats up guys..i was just wondering what gas everyone is useing and what i should be useing. i mean it says to use premium in the honda si brochure.. let me know what you guys think

 

I put premium gas in. If it says to fill up with premium in the drivers manual, why would you do otherwise?

 

Definantly use premium.

 

High compression engines require premium fuel to prevent pre-ignition (aka "pinging" or "knocking"). The Si can run on regular unleaded, since the ECM can adjust the spark timing and whatnot to compensate for 87-89 octane, but you won't get the same performance.

Basically, if you're going to buy a car like the Civic Si, then accept the fact that you need premium. It costs a whopping 20 cents more per gallon. If you buy 15 gallons of gas, that's $3. So, on days when you have to fill up, just skip the latte at Starbucks, and your expenses will balance out nicely.

 

premium like the owners manual says like everyone else says if you wanted something to run on cheap gas buy a ex or hybrid

 

no i am most definite about useing premium i was just wodnering if any1 else was useing anything else and what was going on with it.........my freinds granpa has been putting regular in his caddillacs his whole life hes says its a sceme lol

haha

 

i use super 93+

 

If you don't plan on tracking it and are only using the car as a daily driver to work and back regular gas is okay while the weather is cold.

I have noticed that there is a slight drop in fuel economy (but still it's still worth it in terms of miles/dollar) and a very small increase in idle roughness.

I will switch to middle and then premium as the weather becomes warmer.

 

if you use anything below 91 ur dumb

Its not consider dumb to not use 91. It is only smarter to use 91 octane. When you have higher octane the combustion is more accurate. If your vehicle compression is is say..... 8:2:1 91 octane isn't necessary. But if your compression reads 10:0:1 then 91 is a smarter way to go.

 

Like other people said.. run premium. Yes you can probably get away with running regular, but I wouldn't count on the cpu to detect the ping all the time. Knock sensors are not perfect. I would bare minimum run mid-grade.

 

i'm running 101 all da time now............

I hope you're kidding. On a stock Si?

 

101 is plentiful here in Sothern Indiana, and its only like $.20 more per gallon......so why not?

This is the equivalent to people putting premium in their cars when they're designed to take regular. The "advantage" to putting in 101 is your wallet gets lighter fatser, and that's about it. The disadvantage being your car could actually lose a little power.

Mobil 93 here, always

 

like its freaking epensive to put premium in your car

premium is usually .20 cents more x 12 gallons and its a 2.40

you can afford an Si but not 2.40 extra per fill up?

bleh

Thats one of my hang ups about looking into getting an SI. Do I want to pay that much for gas? Gas is bound to become even more expensive, the SI doesnt get the greatest gasmilage of the civic lineup and I do alot of driving. But then again If I modify the car I have now, id be in the same boat probably.

 

lol try driving around in a prelude that used to get 18 mpg

and you have to put in premium (min 91 but we only have 93 in tx)

now at least i get 25 after a big tune up and some parts

gas is just one of those things where you can't neglect. i'm sure the SI can get good gas mileage (~28) its just usually the driver who needs to control himself and not ever use vtec, but then whats the point?

 

Si 93
All others 87

I get between 28-30 mpg in my 92 Prelude Si. I guess that's pretty good overall, but ya it kind of sucks having to put in premium. I'm quite content w/ the mileage and I'm not too heavy w/ my foot so I'm sure that helps. If I do mostly highway driving I can get close to an average of 30mpg for the tank.. If I do alot of city driving then I usually get an avg of 28mpg for the tank... not bad..

lol we are going OT and not even in the right forum but yeah

i used to have the h23, used to get around 27-28 mpg

but jdm h22's with 345cc injectors instead of 240 cc on the h23, yeah i can't help but use more gas even though i don't drive her that hard

 

car dyno'ed at the same levels with 93 and with 101......now if i wanted to spend money i could get the hook up on some 110low lead.........god i love having a supra owner as a friend that sells race fuel.....

my dad owns a hanger

i can get jet fuel all day even drive on the taxi at high speeds

annually they plane owners have a plane/car show. one guy brought his drag c5 which hit 200 mph on the runway and then crashed at the end cause he didn't have enough room to stop
