Super unleaded vs hioctane

[levin]

Seeing cng vs petrol topics around here, i always consider them diffirent types of fuels required for diffirent types of combustions. So, i thought lets have a bit more practical discussion on how to match your car's engine ron level.
As most of us already know our typical Honda civic with eg: d engine requires 98 ron level set by the manufacturer.

When we drive cars with higher C/R engines they require even higher ron level like b16, b18, rotary13b etc.

Our basic fueling requirment is filled up by hioctane which is recently been pulled off at the petrol pumps, so we can buy either super or hear sorry come again we dont have hioctane at the pump right now.

Even bigger displacement cars bought for 2 million plus need best fuel avaliable here. so we need to compare super avaliable vs hioctane required by engine and what are diffirences and how to meet the requirements.

In Pakistan they water down the Patrol. I have ran all kind of a luxury cars here on regular gas without any problems. I know Ron is different then our Octane system. Our 87 octane is probably 91 RON.

Is it 89 RON? I just don't get the diffrence between RON and Octane.

I went to the petrol pump today and i couldn't get either super or hioctane..

Good, Good
The same topic I was going to post today!!!

[levin]

i bought this as a sample. it brought the engine knock level low to much consenderate level, the white stp bottle for Rs150/- was pretty useless in high compression engine.

it seems the headoffice is in Ireland and it is produced in european community to meet european standards.
It says on can it can increase ron level on scale of 2 to 5 depending on how good the fuel is.I could hear knocklevel decreasing as i emptied half can,, full can is for 60 litres..

I think Octane Level and RON is the same.
RON stands for Research Octane Number.
In pakistan even the Hi Octane Fuel is probably not more than 91 Octane.

[levin]

what would you add in super to increase ron level, hioctane "was" avaliable,, not anymore now.

I don't think any of those octane booster will help. Do any of you guys have access to jet fuel? A mix of jet fuel with regular gas should give you good mix;)

[levin]

i already have asked at aviation abt jet fuel a few times. they didnt give me any yet maybe some others can be more lucky with airforce ppl not me.

[toofast]

Do you have any flght schools in Lahore? Small planes use the same gas too(Y)

[stingray]

guys im an aviator (airforce fighter pilot) and i wud sincerely advise u against ever putting even a single drop of jet fuel (its jp-8 btw) into a car...simple reason is....jet engines dont require the fuel to be as clean as a car does and jet fuel is dirtier then normal fuel available for super cars...moreover the actual grade of jet fuel is totally different and would cause engine seizure if used in a car.
Even the Jp-8 available for cars in the civil is actually a different grade of jp-8 and the one used in jet engines is a different one though both are from the jp-8 family.
I hope none of u is gonna try putting ur precious cars' motors into jeopardy after this advice.

Do check the quality of jetfuel before usage. Over here Kids use them for racing purposes mix with regular gas 20/80 ratio. Any body can buy it for almost the twice the price of the regular gas(y)

Piston engine use

Jet fuel is very similar to diesel fuel, and in some cases may be burned in diesel engines. The possibility of environmental legislation banning the use of leaded avgas, and the lack of a replacement fuel with similar performance has left aircraft designers and pilot's organizations searching for alternative engines for use in small aircraft. As a result, a few aircraft engine manufacturers, most notably Thielert, have begun offering diesel aircraft engines which run on jet fuel. This technology has potential to simplify airport logistics by reducing the number of fuel types required. Jet fuel is available in most places in the world, whereas avgas is only widely available in the few countries which have a large number of general aviation aircraft. A diesel engine may also potentially be more environmentally-friendly and fuel-efficient than an avgas engine. However, very few diesel aircraft engines have been certified by aviation authorities, and widespread use of diesel aircraft engines is still years in the future.

Jet fuel is often used in ground support vehicles at airports, instead of diesel. The United States military makes heavy use of JP-8, for instance. However, jet fuel tends to have poor lubricating ability in comparison to diesel, thereby increasing wear on fuel pumps and other related engine parts. Civilian vehicles tend to disallow its use, or require that an additive be mixed with the jet fuel in order to restore its lubricity. Jet fuel is also significantly more expensive than diesel, so using it in ground vehicles is considered by some to be wasteful.

and somebody here wanted to mix it with hi octane????

[XaxoOBoY]

HmMmMmMzz ... So now what do you guys prefer ? SUPER or hi Octane ?? which is best for VTi Engine ??

[wasay_ahmed]

@levin
have you ever checked STP Octane Booster the1 in Orange not easily available.I used it with Hi octane in the tank better responce whn you floor the paddle even in auto 1.0L:p

[levin]

@wasey
i havent seen the orange bottle

does that say methanol or ethanol on it? what abt adding a litre of these liquids in fuel tank?

[levin]

[highlight]Gentlemen

Start your engines. Hi octane is avalaible at shell now[/highlight]

:d

[rohaansaeed]

yes, just got my Accord Inspire's tummy filled up with Hi-Octane and super! now the G25 is running

[XaxoOBoY]

@levin : which fuel should i use for my car ? Hi oct+super ? or just super ?? Vtec Engine 2002 model civic.
