The Difference Between Regular & Premium Gas...

[geezy]

Ok so ive notice that people always saying premium gas last longer and it does your engine better and give it more power blah blah blah...:blah:
but regular gas it feels the same..
but when i put premium it seems to waste the same amount as regular... whats the difference??? or is it just a rip off?:thinking:

[silverDA]

the diff is premium is for o.g.'s.

[MR2DR]

I don't think it really makes a difference in your car :goodjob:

[geezy]

lol i knoww.. freakin 1.5engine:lmfao:
btw.. swap coming soon:bump:

[david068513]

god your stupid, Ok premium will make more power if your car is tuned for it and yes it burns cleaner. It doesn't help your gas mileage though. Your car will use the same amount of gas.

Thanks for the info
but there no need for your negative comments!!! :no:
it was just a question..im no gasoline expert :thinking:

[jdmdb8itr]

premium is cleaner and burns better and cleaner. and cost more.

[geezy]

oh alright! Thanksss!

[Bacon]

I didn't think too much about the differences until I put two tanks of mid grade in my Focus because gas was $6/gallon. After two tanks of mid, I had to replace all plugs and wires. Definitely a difference between them.

[bstdgsrteg]

and dont forget with boost premium is the minimum you should run, no matter what. detonation FTL

[Black4DrEK]

there IS a difference...sure

More octane = better spark, = better (controlled burn) in the combustion chamber..POWER!! lol

all in all YES it is BETTER.. but in your Single dingle.. DONT waste your money..hah

[geezy]

hehe YET

[Black4DrEK]

Well until then.. keep the regular in that bitch.. haha

[geezy]

Well until then.. keep the regular in that bitch.. haha

Will Do!

you guys arent gonna believe me and this fine but im about to drop some PERSONAL experience on ya.

my dad did a test on what was his daily a few years back. 02 chevy 1500 4.3L VORTEC automatic. he ran 2 FULL tanks of....

87 oct
91 oct
93 oct

through his healthy truck with like 40k miles on it. all grades of gas were from amco(sp?) gas stations. he calculated his MPG for each grade of gas. amco ultimate 93 oct gave him such a better MPG that it actually made 93 oct cheaper in the long run. the price difference in the grade of gas was out weighed by the increase in MPG.

he had everything written down and i was at his car lot when everything was added up. looks at my for sale thread for my 98 chevy blazer that i sold about a month ago....

nothing put 93 octane gas since i have owned it



needless to say, ive seen the results and its cheaper to use 93 oct. if you dont believe me i suggest you do your own test like this :goodjob:

[Bacon]

I just use 93 octane out of habit anyways. Hell, if I am driving my wife's Pacifica it gets 93 octane. Good test there CH@Dbee. I haven't paid attention to my mpg but I know that my cars run better on 93.

[Evil Goat]

what if your car would rather have c16? :ninja:

[ash7]

After two tanks of mid, I had to replace all plugs and wires.

how did 87 octane mess up your spark plug wires? :thinking:

-jonathan

[Bacon]

i wouldn't drive it everyday thats for sure. i know c16 made my dads terminator run so much better at the track last time we went to SDR.


how did 87 octane mess up your spark plug wires? :thinking:

-jonathan

i went ahead and replaced the coil pack and wires anyways with aftermarket. stock ones were shit when i got the car to begin with.

[jojeezek]

theres a big difference in cost.....lol

[geezy]

so putting cheap gass could mess upp yourr engine

[Umby]

Nah, it won't mess up your engine, man. 99% of cars are made to run on 87 octane.

You need to use premium if your car is made for it, if you have advanced timing, or your boosted.

93 does burn cleaner so its not a bad thing if you WANT to run it but you don't HAVE to run it.

Bottom line: you're fine

[marcos713]

i heard the difference was the something with the way it burns in the combustion chamber. :thinking: forgot exactly what i was told

i just know my friend has a pontiac GTP and it only takes premium. during the gas shortage he put regular and the car ran like shit. he had to use some octane booster..

[preferredduck]

there is a difference i know for sure. 92 octane has a higher octane rating and has more energy than 87 octane. typically you use premium in high compression motors because there is not alot of room for compustion to take place. my SI runs premium only and if i don't it runs like crap and i get way less gas mileage. stick with what your call cars for, it it is designed to run on 87 octane then that is all you use. i bet alot of people with b16 swaps don't put premium in their cars.

it does not add power or make you go faster you actuakky kose HP and MPG.

x2 haha..

If the car calls for premium deff use it.. IF you need gas in a hurry for a few miles and REGULAR is all you can get. thats fine but NOT for long, eventually it will fuck up.

so IF and when you get your B series VTAK swap, dont cheap out on gas. That goes for all cars that "should" use it.

Also Dont go Putting super High octane gas in the car THINKIN its gonna run super good, cause it AINT!:goodjob: unless its tuned for it.

to be honest, i have no clue what the 4.3L VORTEC chevy motor calls for but it DID make my dads truck run better. his MPG was alot better with 93 oct than 91 and faaaaaaaaaar better than what he got MPG with 87 oct.

i dont own a gas station so you guys do what you do but i did want to share the information about what i know :cheers:

As i said in post 11:goodjob:

[japan4racing]

a couple months back i aquired my dads old 1990 toyota pickup. this thing had seen nearly 20 years of 87 octane. it started running rough in jan. of 09'...my dad parked it right then. it sat until i got it back in october. the whole time he owned that truck he never got better than 20 mpg..its a 4 speed (no overdrive)...after i got it i cleaned the carb and started it on a healthy diet of 93 octane. my last tank was 24mpg. the reason it was runing rough was from some trash in the carb. alli did was spray it out with carb cleaner so its not like its a fresh carb. 93 octane gave me 4 mpg over the 87 it has been running for nearly 20 years...i would say 93 is worth running. my stang gets nothing but 93 and all my hondas got 93 (they were turbo gsr's...3 of them)

[toxxxic]

if your motor does not require premium, you're wasting your money.

it doesnt make you faster, it doesnt make your engine last longer. if your motor was meant to use 87, then use 87. not that hard of a concept.

[BAD SS]

So much misinformation in this thread.

Higher octane prevents pre-ignition. That's what it's meant for.

Unless your motor is pinging, you don't need premium.

I don't know why people get the misconception that running a higher grade fuel in an engine meant for 87 improves performance in any way. 93 is meant for ignition systems requiring a greater spark.

[Destineal]

I use 93 because my car demands it.

[TougeGTR-33]

This is just the thread i was looking for! Ive been arguing with a friend of mine for a while about this. He keeps saying that i dont have to put premium in boosted cars lol Even mine being a 1jz supra with a big single he still swears that you dont have to rum premium. LOL!!

[mocha latte cupcake]

s2k no <3 anything but 93.....

[David88vert]

So much misinformation in this thread.

Finally, someone says the truth.

Octane has nothing to do with the amount of energy in the gas.
It is simply the measure of resistance to auto-ignition.

[blown_ss]

how did 87 octane mess up your spark plug wires? :thinking:

-jonathan

i was wondering the same thing. i just figured he was dumb as shit.:D

[Theycall_Metue]

if your car needs 93 then use it, if its not require, dont waste money

[BIGRICH]

whats the difference???

have you ever used regular in a high compression build?

[Batlground]

The reason that you get better gas mileage on 93 is because the oxygen sensor closed loop feedback along with the knock control on newer cars allows the ecu to run more timing and less fuel. With the 87 not as much timing can be run and if it senses any knock noise it adds fuel as well.

The difference in 93 and 87 is the auto ignition or detonation point. The higher the octane the more pressure and temperature it takes to auto ignite or detonate the fuel.

from another forum....



Using regular 87 octane, it will cost me $142.19 per month in fuel over 2200 miles.
Using premium 93 octane, it will cost me $133.08 per month in fuel over 2200 miles.



from what i have looked up this morning i think it depends on the vehicle itself. like many people have said if you car wasnt built for 93 oct it wont make you car faster LOL but it could save you alittle money or break even for cleaner gas that will make your car run better.

[MINI]

I have noticed that my car is slightly sluggish with 87 and it SUCKS IT DOWN.

With 93 it's normal and sips on it.

[KevinT707]

If you're motor isn't designed to utilize the properties of a higher octane then just stick with the 87, sheesh! If you're really skeptical then run Chad's test and find the results for yourself.


premium is cleaner and burns better and cleaner. and cost more.
.. Don't think so buddy

Good idea that people could test out. Of course not all cars may see results such as this.

Savings a month= $9.11

Savings a year= $109.32

5 years= $546.60

I put premium in my old Civic and noticed a difference automatically. Just remember Grades just have to do with Octane levels not the quality of the gas. That is why you pay more at a Chevron or Shell compared to other places. Their gasoline itself is better.

yep! and QT has some of worst gas out there! their 93 oct make my 350Z toss CEL's and run like shit.

[bdydrpdmazda]

I know that if anything goes in my tank besides premium, it will make my car run like shit. My wife tried to pull a fast on me one day by putting mid grade in it and i knew as soon as i started driving. There is a difference, i just dont know what it is. STi needs the good stuff...

[geezy]

yeah i notice minee runs better on 87 & on 93 it gets kinda dumb:screwy:

[5speed]

Thats running rich for you car lol

[BAD SS]

Never had a problem with QuikTrip gasoline. That's pretty much the only brand I use, other than BP on occasion.

[CHADbee]

maybe its because you have a lower compression motor than my 350Z did.....or i just had a bad batch of gas....i dont know.

[Vteckidd]

All cars are designed to run 87 octane under normal driving conditions, but higher octane burns better and "cleaner" as it's more efficient burn

amen i accidentallty put midgrade in one time and about 5 miles later had to do premium and my brothers cocktail for an octane boost so it would run right. i could immediately tell it was the gas and went DOH!!!

This E85 crap they add in now has dropped my gas mileage from 350 to 300 miles per tank which makes me buy more gas. i smell a gov't scam here to get more revenue, only if you ask me though cuz according to total blender me and my cat wear aluminm foil helmets, but i see through the BS. octane boosters have been tested and really dont do much, except maybe run hotter, same as higher octane it is a hotter spark in the chamber so don't destroy your shit. if you do sell it to me.

[.blank cd]

You see through the BS and still buy octane booster?

[preferredduck]

to be honest, i have no clue what the 4.3L VORTEC chevy motor calls for but it DID make my dads truck run better. his MPG was alot better with 93 oct than 91 and faaaaaaaaaar better than what he got MPG with 87 oct.

i dont own a gas station so you guys do what you do but i did want to share the information about what i know :cheers:

it depends on the setup and motor, some engines are detuned from the factory and if you do some mods and run premium it will do ok. example my brothers 89 GT with 64k miles on it gets massive power gans from simple bolt ons because it was detuned so much from the factory. really do your research from a crdible source before trying it, i kow after aall my bro has done to the car he still runs 87 not 93 like me.

[preferredduck]

thats what i was trying to say lol!! reps

and fixed as well:D

thanks for the corrections it was late as hell and i was typing way to fast in bad computer grammar. lololol as far as your buddy in the gas shortage i had 2 stations that fro some reason had premium refilled, but if i couldn't get any i drove the 40mpg hatch that ran 8 octane.

[preferredduck]

You see through the BS and still buy octane booster?

this was when i was 19 and had my first SI and freaked out about it. i wanted it to be at 93 instead of 89 octane. make sense to ya now. my clumsy mistake led me to do ot. never again though.
