Do you get more Kilometer on a high Octane Gasoline?

[MAXBUWAYA]

I think Im getting more kilometer on 95 than on a 93.

We all know 95s are more expensive.
But since I started experementing I think am getting more on 95s.

Or maybe am just that bad with Math.

Any statement/comment to this?

[OTO]

If your car needs higher than 93 then you'll get better fuel economy. If not then you're imagining things.

whats your car?

[Karding]

If your owner's manual says REGULAR, then so be it.

this LINK is a very good read.

How did you measure your kilometer per liter?

[MAXBUWAYA]

Well all the manual says that its safe if it wont go below 93 and wont go up to 95

Car was the ECHO verso
If i fill it with cheap 93 gas, theres a severe difference in acceleration and yes it consumes more I think on 93

Now its the 03 CRV
Not much diff with engine response on cheap 93 gas
but also gets more kilometer on 95

(tagal ko na gusto itanong ito eh! hehehehehe)

Is it the car?
Do chicks love the car?

[MAXBUWAYA]

Its total distance dibaydibay by total liter di ba?
Or mali ito

[Karding]

Its total distance dibaydibay by total liter di ba?

:hihihi:

tama yan kapatid, dibayd total distance to the liters you pump the next time.

Kung tama kalkulasyon mo kapatid, eto ang conclusion ko:

93 - galit ka sa gas pedal dahil ang tagal mag react so you consume more gas.
95 - konting kadyot lang ng gas pedal, arangkada na agad.

di vah di vah?

Ang solusyon ko, konting pasensya sa 93 octane at dahan dahan sa pag arangkada. Afterall, ekonomiya ang target natin di ba?

[Karding]

See, etong 240SX ko ang nakalagay sa manual regular octane. for more performance, use premium octane. True enough, I consume more gas on lower octane than higher octane dahil ang tagal bumatak kapag sa regular lang.

[ghosthunter]

given the gas prices... adding acetone to gasoline to extend fuel milage is a must for me these days.

[mazdamazda]

Now its the 03 CRV
Not much diff with engine response on cheap 93 gas
but also gets more kilometer on 95

that's because the 03 CRV requires 95 octane gasoline.

[j_avonni]

Before, alternate ang karga ko ng 93 & 95. Pag ako bayad 93. Pag iba 95. Computation ko halos pareho lang.

Here's the logical approach to the question:

An engine's power-producing efficiency closely correlates with how optimum the spark timing is, among other things (but let's just concentrate on spark timing for now, cause that's the aspect that mostly relates to the gasoline octane). Optimum spark timing is somewhere around 7-13 degrees BTDC, whereupon the combustion occurs right when the conrod and the piston are in the best position to kick on the crankshaft. Any more advanced than that and the piston is going to "kick" a little too early, and a little more later than that, well, it'll be a little too late.

Problem is if the fuel does not have enough "self-ignition" resistance, once the spark plug starts the flame kernel, the sudden increase in combustion pressure will cause the "end gas" to ignite on its own. This will cause 2 flame fronts to collide, causing a violent explosion inside the chamber that we hear as "knocking" or "tope".

Knocking is a wasteful kind of combustion because all the energy of the gas is concentrated on a very little span of time, thereby not allowing most of the energy to be converted into useful "work". Because less of the fuel's energy is converted to work, there will be less of a distance covered by any given amount of fuel, hence less fuel efficiency. In addition to that, EFI-equipped engines automatically retard the fuel timing, thereby reducing the engine's efficiency. Besides all that, it is such a violent reaction that it can cause damage to the engine if allowed to occur too often.

One way to minimize, if not, eliminate Knocking, one has to either retard the timing or use more expensive higher octane fuel. So the bottomline is, are you going to be saving more money using lower octane fuel and travelling a shorter distance, rather than spending more money using higher octane fuel but travelling a greater distance?

for some reason, parang mas ok ang andar ng ae92 xl namin pag 93. i loaded it with 95 once, parang humina ang andar. labo no?

[ale828]

in a 03 CRV with a VTEC engine, i think a 95 is good for it but a sometimes you might be find the better fuel economy on the 95 octane because you usually press the gas pedal more if you use the 93 octane to acheive the desired acceleration. it all actually depends on your driving, If you drive economically on the city i think the 93 octane is acceptable for smaller engined cars but the 95 octane would be more benificial on highway driving.

[maop99]

Tried to change it once parang pareho lang, try ko nga ulit baka may difference na ngayon? hehehe

[chieffy]

more mileage ako sa civic 1.6 kapag 95 RON gamit ko...

[raikonnen]

ako din more mileage ako sa 95... naka 97vti naman ako...

[Karding]

maidagdag ko lang na parang hindi ko ramdam ang price difference ng regular $2.31/gal and premium $2.51/gal. It looks like it boils down to the car's fuel consumption.

10gallons of regular is $23.31
10gallons of premium is $25.51

Now, what can I do with $2.20?! McDonalds burger? hehehe

AFAIK, Honda (newer VTEC engines) requires an octane rating of 95 RON, because it is a high compression engine, anything less than that will make it burn more fuel. So it really depends on the engine requirements.

[raikonnen]

pero sa states ang baba ng octane rating nila, lalang... 87 pinaka mababa nila... pag naka 93 auto nila tuwang tuwa na sila. tyo parang halos itapon na natin ang 93 octane hahahaha....share ko lang mga dudes =D
