Gas brands

[Urbanfer]

What do you gyus prefer to use thats great for your engine? Add details of the additives used in the gas etc why its good and why its bad

[fckillerbee]

there have been threads like these before. do a search. all gas is the same. fyi.

[murda-c]

for a while i've just been getting shell on thursdays when its 10cents off at the station near my job.

because the commercials say it's good.

additives are different

octane levels may be the same

I know a lot trust Chevron and Shell ;)

[project-D180]

93 is the best ..plus it it gives u better gas milage if u believe it or not..im not to sure about the additives they sale like octane boost.now if u can get some e85 n mix with some 93 octane thats the ish

i don't think you can mix E85 and 93?

due to the fact of the timing needed to run Ethanol?

[voodoo_child]

76 and chevron. 89 and 93 pref but once a in a while try putting 100 octane

[project-D180]

u can mix it jus can use a lot of e85 though.quarter tank n rest gas

[badbob2121]

are you asking what stations to use? or like octane ratings?? think about questions before you ask them

[Urbanfer]

I never knew you could mix he gas up without it messing things up

you should know that all commercial gasolines are diluted with a surprising amount of ethanol. this isnt anything new.

well when he said mixing i would assuming he was meaning a large amout.

and since ethanol in E85 is corrosive it will eat up rubber/aluminum lines, plus the fact e85 requires what like 35% more fuel, plus the timing you need to run to run E85 efficiently i just don't see a LARGE if any increase in power/efficancy

[handinpants]

There is a 76 station in los angeles on the northeast corner of doheny and pico, this gas station is one of the few in my area which has a separate hose gun nozel thing for each grade of gas, unlike many places which has one hose for 3 different grades of gas. What I fill up at this station I use 91 octane (stupid california not having 93 octane) I feel like my car runs better and the car would get a bunch more extra miles per tankfull, and I feel thos happens because this gas station's pumps have their own hose for each grade of gas, which means I am not mixing a hose length of the last guys 87 octane. Oh and my car responds better

It doesnt eat up your fuel lines it cleans them.Thats why you change you fuel filter a few times when you convert because it cleans the shit out of your whole fuel sytem. Yea that might not be good for your 20 year old fuel lines but they should have been changed by now anyways.

Back on topic, I honestly never noticed any difference between say, Arco and Shell so i always got what was cheaper. However there is a noticeable difference between different grade fuels.

[cheesyriceo4]

When I used to be rotary powered, I had a 190,000mi. never rebuilt N/A 13B. I could tell a huge difference in fuels such as Chevron, 76, and Shell. Chevron ran the best but it burned the fastest, with a 2-3mpg drop (compared to 76 and Shell), along with a richer smelling exhaust scent. Shell and 76 gave me the same gas mileage but 76 was beaten when it came to smoothness.

...But then again, this is all just me doing pseudo-scientific "experiments".. ;x

i'm sure you do...there was a thread like this, it was"whats the difference" and it came back with a driver saying that he drove to shell, chevron, arco, and mobile, with the same gas (several truck drivers said this actually), and put in in the ground the same at every place (and they all said they've never seen anyone add anything once the gas is in the ground). The additives never changed. There are two different grades in gas, but nothing is different from company to the next. All say it's different, but that's in comperitive to a shittier gasoline (better tier, worse tier).

also, I onced talked with a "tuner" and he said use the gas recommended for the car, as in, the higher the octane, the harder it is for your stock car to burn the fuel, resulting in slight loss of power.

always, this isn't first hand experience, so I could be wrong, but I did do some research, and this was our results. So if you have some missing info, I would greatly like to hear it. As I want to be proven wrong, and buy gas at the best gas station.

i get costco lol, its the best and hella cheap

No you get better gas mileage because its burning your fuel efficiently your car is an SR so it hates anything but 91 its supposed to run a higher octane because one its turbocharged and two in jdm land they run higher than 91 as a low octane gas . Lets say you have a Toyota tercell and you put 91 in its going to run like shit because that motor was not designed for it. High compression you usually have to use a higher octane. People think 91 just makes your car faster that's not always the case. Some times it makes it worse. as far as the different hoses go I doubt that has much affect

[Mishkin_707]

i always used chevron, but in chicago there is no chevron so im stuck using shell, always liked shell so i wont complain

It is true that running premium fuel in forced induction engines provides better efficiency than in low comp/older engines because of the extra buildup of pressure. Although, per Nissan it is acceptable to run premium quality fuel 91-93 octane in our NA KA's without detonation but that still doesn't take account how much compression loss your engine might have due to age... So basically its your call as to how much money you would like to spend. Octane rating is just the fuels ability to resist detonation, or the amount of heat and pressure it takes to ignite the fuel efficiently.

As far as Japan land goes their unit of measure differs from ours in the States. They use the RON Research Octane Number system to determine octane rating were as the US uses the AKI Anti-Knock Index to determine our octane rating. Multiply the Japanese RON octane rating by about 0.95 and you will have the US AKI measurement.

I'm not sure what low grade fuel would be in Japan but heres some higher grade examples.
98 RON Octane x 0.95 = 93.1 AKI Octane
100 RON Octane x 0.95 = 95 AKI Octane

There is very little difference between our octane ratings and those of Japan/Europes... If there were JDM engines would have a hell of a time running in our cars efficiently.
