HELP!!! Gas choices

[xXxMattxXx]

well im getting yelled at by my stepdad for "wasting money on gas" i got mad because he filled my tank up with race-trac regular gas and i said that my GSR needs premium and he got mad at me because he pays my gas and he said it doesnt make a diff. I've read that it does can someone tell me if using premium is better or if its not

[Tenacious G]

pay for your own gas, fill up with premium like your car requires.

problem solved.

Depending on the car, yes they do make a difference... If your car says it needs it, then I'd do it to be on the safe side. Tell your idiot step dad to stop being so ignorant too. There is a reason regular is 87(or 89? Don't remember) octane and the supreme is 93...

If that doesn't convince him, tell your mom he's beating you and sue his ass.

[Houston hb]

man if you dont use 93 in a gsr then that engine is going to go to waste.. always use 93 for any honda engine you care about.

[SecretAgent]

only the H and B-series VTEC motors are tuned to run 93 octane. all others run fine on 87.

oh, and so are the VTEC V6's and the new K-series motors.

my cars gauge says premeum unleaded fuel only.... sticker on the apr says 93 octane..gotta represent :rock: or mabe i just forget. and need reminders.... :ugh:

[sherpagoodness]

race trac gas is cheap watered down shiot...and yea premium is worth the extra money on ur car

[WRXTuan]

Get a job. Them pizza delivery guys have "gas money" included with regular pay :thumb: Yeah, keep your car running with the stuff that it needs.

[mike_do]

like everyone else says, get a job. but i say just pay the extra 10 cents or so per gallon :thumb:

i doubt that race track puts water in their gas...and if they do go get sum 93 octane gas at race track and drive ur car around...when u fill it back up go to chevron get their 93 octane and about 3 gallons of water in ur car and tell me if ur car runs the same when u had race track gas in there..... :rolleyes:
oh and if ur car needs premium get premium...if u dont it'll foul up ur o2 sensors and make ur motor knock a lil...i used to have a mr2 turbo and my dad accidently put 87 in it and it ran like shit...he apoligized and towed it to a shop to syphon it out for me lol....and if ur step dad put the 87 in y dont u put sum octane booster in there....dont shoot me down but iono if octane booster works...i hear they only boost the octanes in 87 gasoline....

[pwr2killayak]

my trusty saturn says unleaded fuel only, the cheapest


poor ppl w/ premium required... :-/

[desenutz]

is it good to get regular..and then sometime get premium??and then switch back and forth u know what i mean??
on a 95 integra ls motor....

Never good to switch back and forth. I never understand what the big deal is between using premium and regular gas. It's not THAT much more and it's better on the car. Do you use cheap oil? or cheap parts? Okay some of you do, but it's not good on your car! :thumb:

[Alex16]

man if you dont use 93 in a gsr then that engine is going to go to waste.. always use 93 for any honda engine you care about.


Exactly :thumb: thats why i run 87 all the way baby!

i didnt mean it that literally....but chew on this for a second, you only see one gas truck driving down the road, do you think 3 seperate trucks come for the diff octaine ratings? its just something they add when they fill up the station's tanks. on ocassion other undeseried objects or fluids may enter those tanks and you may get a tank of bad gas. i had just heard race trac was cheap shitty gas.....dont get me wrong tho, ive gotten bad gas at shell and chevron too

[Boost_it]

i thought race track was rebagged exxon? or maybe thats krogers/randals.

Anywho, I am required to run the good shit.. says it in my gauge cluster and on the gas door. You should be running premium, regaurdless of what the old man says. I would add some octane boost (like 2 bottles) and take it easy on the car.

Why run higher octane?

1. higher octane slows down the combustion process giving you a slower, more controlled burn.
....A. advantage to this is that it allows you to increase your timing, and/or compression as you're less likely to have detonation.

....B. advantage is that it helps to prevent pre-ignition, preventing detonation from hot spots in the combustion chamber.

....C. advantage is that you can run run more advance, and/or higher boost levels on forced induction vehicles, the slower burn helps to prevent the combustion process from blowing up, rather allowing it to burn(when it blows up you have bent rods, burnt valves, holes in pistons...)

....D. advantage is that you can run nitrous oxide with more ignition timing, and a smaller chance of pre-ignition AKA detonation.(read C above)

....E. disadvantage is that if you don't have the car tuned to run specifically on the higher octane gas, you'll end up with less power since the combustion process is still attempting to burn the fuel when the exhaust valves open, dumping still burning fuel into your exhaust.

....F. disadvantage is that it's going to make your wallet considerably lighter.

That's a post by Austin who tested the theory of Higher Octane fuel performing better, which we all know is crap. If you car is tuned to run on 93 Octane then put 93 octane in it. Detonation is bad, and unless you have cash to burn, I'd rather spend $.06/gallon extra than $2-$3k on a new motor.

-if the car prefer premium, then pump premium.
-but usually on newer cars, they all have some kind of engine management to sense if the car detonate/ping, then it tell the computer to retard the timing/ignitions.
-if you have the LEV effficiency craps, then am sure that you can just use any kind of grade. newer cars are built to operate on the least expensive unleaded grade, but its always good to buy the higher grade if you got the money.

Not to be a dick, but can you read? Look up at my last post. If the car says to put in premium, use premium, if it says to use regular, use regular. Do not mix and match octanes, and do not put higher octane in your car, if it does not require it. The higher the octane the slower the burn, basically. So if you are putting 93+ octane in a car tuned to run on 87 octane, that unburnt/burning fuel is dumped into the exhaust system.

Tell your pops to get you an alky injection kit otherwise 93 is going in.

Higher octane doesn't always equal slower burn, all octane means its more resistant to detenation. Slower burn has to do alot more with Specific Gravity and how oxygenated the fuel is than octane count alone.

[Havokmkr]

You are correct, but don't get too advanced for our audience. Although the definition of octane does include burn rate, they are related. The point I was trying to make is higher octane will do nothing for you, performance wise, except to save you from detonation. So some little kid with a mildly modded car w/basic boltons shouldn't worry about what octane to run. Just put what the owner's manual tells you to put in it and stop wasting your money.

For those who don't know what octane is...
Octane ratings tell you how much the fuel can be compressed before it spontaneously ignites. When gas is ignited by compression instead of spark, that's detonation. That's when knock occurs, and when you want to start running a higher octane fuel, or retard the timing to account for it.

race trac gas is cheap watered down shiot...and yea premium is worth the extra money on ur car

they are a major corporation, whose pumps and tanks are tested on a yearly basis. they make millions of dollars a year, im pretty sure they can afford to send 3 trucks for their 3 different kinds of gas.

oh, and btw, even if they don't send 3 trucks, that truck's tank can have several different compartments to store the different octanes.

so, please, don't spread lies and rumors unless you have more proof than, you only see one truck.

[Havokmkr]

SecretAgent is correct. At least as far as the racetrack on 2920 is concerned. They have one truck that comes to deliver all the gas. If you notice when he fills up the tanks, he connects the hose to the next valve down when he moves on to the next tank. You can use common sense to figure out why he does that.
