Best Fuel for Ordinary Cars (RON95)

There has to be a pressure release valve somewhere. Otherwise how does it handle the pressure from the gases?

Not sure about newer cars but older cars got this charcoal canister. I think this is the canister handling the fuel evaporation.....

had the charcoal canister before,but ditch it somewhere in the dustbin.muahahahah.
it just my messy engine bay messier.hehehe.

Petronas consistently give better mileage than Petron. Petron is my regular fill.

take note that evaporation differs from boiling...

evaporation only happened at surface (liquid to air), while boiling happened inside the liquid (where the liquid got the energy)...

in a closed container (fuel tank), evaporation happened inside, but it will finds its equilibrium somehow...

im sure it got release valve somewhere, but i think its controlled by pressure..very hot day, yes, but not everytime...

evaporation accelerates when you open the fuel cap...release the pressure, and the evaporation happens...
you know that petrol (gasoline) evaporated really fast...

that's why refuel on cold day only... :proud:

Then you're in trouble. According to the big fart... I mean big kahuna, he announced on national tv yesterday this hot weather will last through March. Nights it's impossibly hot too.

I hope your car fuel consumption is reaaaaaaaaaaally good.

Means newer cars still have.....:hmmmm:

Theres several threads on lowyat.net. I think the more recent one had a post by http://christopherteh.com/blog/2011/04/fc/ who has done some leg work and found out Petronas gave better mileage for highway driving.

haha! so is it a myth that people say stick to one type of petrol and don't keep changing it ? because my uncle use to follow this principle and he tells me to do so .


Happens to me all the time with my family

like hell yeah, got the kelisa for the 1st time, newbie to cars oso, been told exactly like u'r uncle did, & guess what stick to the principle until last 3 year coz for the very 1st time no other petrol station around oni Caltex that time, by hook @ by crook need to fill in, later ask fren & guess what, he laughed like belly want to burst & I was like huh wth. now just stick wit PETRONAS coz points can redeem almost anything in mesra shop. time of filling doesn't matter coz it's to small to relate to our usage lehh

Y bother so much bout the evaporation? you park your car under the sun it evaporates faster than you can save. And one wrong tap from the right foot, there goes a big gulp of fuel.

I'm using Petronas for my car coz it's easily available. Imagine you gotta go to a specific place for petrol, lets say, BHP or Caltex (they are rare), you lose petrol just to go to that place. Unless you pass by the station everyday. All brands have cleaning properties and some might give more power. So go to your favourite "power" fuel brand only when you want more power...if not, they are all the same to me lol

The best fuel for ordinary car users is the one that gives the biggest discount. Go work for an oil and gas and use their company discount. Since Petron took over I get less discount but still better than outside. 26% overall and no more than RM1k rebates per month. :proud:

I suggest we dislike his comment. Agree?

 

[twistedichc]

But for me, when I go refill when open fuel cap, like got vacuum??

same as me, if fill till full & then takes days to refill + refill under the red line(supposedly using the reserve portion), once opened the fuel cap u can hear air rushing in like there's a vacuum space inside the tank. so the question is y there is vacuum & how supposedly the pressure inside the tank regain it's balance??

Good point!

Having said that, as long as your petrol tank is exposed to heat, petrol will evaporate in your tank. There's a release valve or something that allows the vapour to release to the air too so does that mean you lose petrol as long as you park directly under the sun?

actually I've read somewhere on how to save fuel and they say if u park your car directly under the sun the petrol actually evaporates and they recommend parking in the shade but I still think the outside temperature would still effect the fuel consumption .. correct me if i'm wrong
