Lets talk about gas!

[Ch|p^^]

Hmm.... sorry ah, baguhan kc me... kaya gnito question ko.


Whats the diff between the diff kinds of gas? Yun ba ung Octane Rating? If so, Ano ang Octane rating ng Velocity, Vortex Gold at ung sa Petron? hehe di ko alam name nung sa Petron eh.


At since we're talking na about gas, what kind/brand do you get? Talaga bang may ibang "hatak" pag yung ganung gas ang kinuha mo?

[squala]

On paper:

93 Octane: Shell Unleaded and Premium, Caltex Vortex Silver and Petron Unleaded
95 Octane: Shell Velocity, Caltex Vortex Gold, Petron XCS and Total Fuels
97 Octane: Petron Blaze

Right now I use Velocity because the car feels lightest there. Shell claims that it is the overall formulation and not the octane rating of the fuel that determines which one is the best. For instance, Total claims that their fuel is 95 octane, but it is way inferior to Velocity.

Blaze is also good, but it is now a bit more expensive than Velocity. So I'll stick with that.

[ssaloon]

blaze gamit ko sa car ko... you can feel the difference sa hatak ng car when you compare to regular unleaded fuel.

and if normal driving circumstances, e.g. di mabigat paa mo and cruising speed ka lang, it increases your fuel economy

pero pag hataw ka ng hataw, madali syang mauubos versus their unleaded counterparts.

[otomatic]

96 octane lang ang petron blaze. Ito gamit ko ngayon sa ride ko. Ibang iba ang hatak compare to caltex silver, gold or protec by total. Konting apak lang sa gas pedal ramdam mo agad ang hila sa blaze, mas pino pa ang andar ng makina.
IMO mas matipid pa ang blaze in the long run dahil mas efficient ang engine and less prone to pinging/tope ang makina.

Next time i'll try shell velocity naman. :D

wow, you have a high octane rating there huh...here in US our highest is 92 octane for automobile use...our octane rating are as follows...we have the 87 octane...89octane and 92 octane..these are all unleaded gasoline...i'm just wondering
thanks

Cale,

The grading system for fuels here in the Philippines is different from the US. Ours is similar to what is used in Japan and in Europe.

AFAIK our 97 Octane fuel is equivalent to a 94 in the US.

hi! i'm new here and out of curiosity, i was looking into the octane rating used in Philippines vs US at dito ako napadpad. anyway after some internet researching I think both countries are using the same octane rating system. before that, a post i found at hondaswap.com briefly describes in lay terms the different octane ratings used around world.

" In Europe 98-octane gasoline is common and in Japan even 100-octane is readily available at the pumps, but this octane nomenclature is misleading to Americans as foreign octane ratings are derived entirely differently from our own... So, like every other measurement system it seems that everyone else uses a different scale than we do, but unlike most other instances where we have had the good sense to create different units of measure in this case we all use the same name...
Japan and Europe use a system called RON or Research Octane Number to determine the octane rating of their gasoline, while stateside we use a system called AKI or Anti-Knock Index to determine gasoline's octane rating... Interestingly, to further complicate things it would seem that our own AKI system is actually derived from the average of the RON system and another more complicated system referred to as MON or Motor Octane Number... So, to recap our methodologies for measuring gasoline's octane rating are different, but share some common elements...
So, with the commonality of RON in mind a good rule of thumb is as follows, multiply the foreign RON Octane rating by 0.95 and you will have the US AKI equivalent.

( RON Octane Rating x 0.95 = AKI Octane Rating )
98 RON Octane x 0.95 = 93.1 AKI Octane (US measure)
100 RON Octane x 0.95 = 95 AKI Octane (US measure)

So, as you can see the 93 or 94 octane fuel we are all paying an arm and a leg for is actually quite comparable to the higher octane fuels found in Europe and Japan. The people whom have to worry about low octane rating are our friends out west in places like California that are subjected to substandard 91 octane.
91 AKI Octane (US measure) = 95.5 RON Octane"

here's the link for reference: http://hondaswap.com/reference-mater...ratings-59435/

now, how did i end up thinking that both US and Philippines use the same rating? my answer is its in the law..RA 8749 or the Clean Air Act. Sec 26 says ".. no person shall manufacture, import, sell, supply, offer for sale, dispense, transport or introduce into commerce unleaded premium gasoline fuel which has an anti-knock index (AKI) of not less than 87.5 and Reid vapor pressure of not more than 9 psi." i'm not saying that this is the law that specifically states the use of the AKI system. i presume that since the law has used the AKI system it must be the system currently in use.

Not necessarily. Gas stations here use RON not the AKI rating system.

AKI of 87.5 is equivalent to around 92-93 RON. Entry level unleaded fuel sold here (assuming the fuel isn't adulterated) is 93 RON, which means our gas stations are still compliant even though they use the RON rating and the law uses AKI.

WOW! just found out that it says on the gas cover of our CRV "unleaded only" pero we've always used shell premium and caltex gold (which is the equivalent of shell premium i think..).

all this time unleaded pala dapat, should we switch to shell unleaded or caltex silver?

Sir, we only got two types here in the Phils. Unleaded and Diesel
Unleaded only has different ocatane ratings. Shell Premium and Caltex Gold are still unleaded but termed as Premium because of higher octane rating, which is normally on 95 RON. Sea Oil has one premium (Extreme) that has 97 RON.

Diesel is of course diesel. Some are synthetic and others are biodiesels.

LPG is also one.

so when your car manual says "minimum 100 octane" assuming that the car is a japanese import your using 4-5 octane points lower when you fill er up with blaze or velocity???? eh di we aint gettin our engine up to its full potential?

[RS Sprint]

Yup. That's why here i don't get the as quoted BHP figure of my car * the crank / flywheel.

[splerdu]

Japan's 100 octane translates to about 110-115 octane here on in europe, and 105-110 octane in the US.

Shell's "reduced octane" gasolines are not actually octane reduced, but the advertised octane is lower to prevent legal trouble. I got this confirmed from both Shell UK and Shell PH. Velocity (Optimax) is still guaranteed 97 minimum, but they advertise it as 95 in case some unscrupulous gas station mixes it with SUL and lowers the rating. Basically it saves trouble for the parent company.

[1D4LV]

used to use a shell/petron unleaded lang sa car ko. pero napansin ko, may minor engine knocks pa.

switched to petron xcs plus, with octane rating 95 ron. nawala knocks. cheaper than blaze or velocity.

[mazdamazda]

petron blaze 4 the rav4 - mileage really improved especially that i've paired it with caltex havoline energy. my average is 9km/L

petron xcs 4 the 323

sir, conflicting yung explanation mo sa sinabi ni RS Sprint.
tanung kung alin ang totooo?

sir, is this mean only for shell velocity or sa lahat ng gaso?

[irmscher]

As long as you don't hear any knock, you're fine. Not all cars need or will benefit from the extra octane of those "designer" fuels. It's mostly marketing anyway.

[RS Sprint]

Splerdu is most probably right whereas I'm mistaken. He knows more about these things.

[wrecker]

my EK is comfortable sa mga 95 octane na fuel. may engine knock pag lower ang ginamit ko.

[rensom]

Lahat ba gasoline ngayon ay unleaded? meron pa bang leaded gas na available sa market? Kung sa shell... ang super at premium unleaded is unleaded talaga? yes... its unleaded, pero yung velocity at V-power is leaded na?
