ok, so they say dey manufacture super and premium with a specific octane rating..but that's at d point of manufacture. by d time they store and distribute, and store again, is it wat u actually get at d pump? anyway of confirmin this? there's too many " if's" on dis topic. I'm willin too try super but not at d expense of "if"..and while i jus drive a b15 i'll tek my chance with d premium in d meantime. i've been gettin d same mpg for the last 3yrs (29 mpg)

Cool I didn't know about the narrow flammability limit but how diffcult is it for CNG to ignite?

From the looks of it, Mr. NP ain't know the ass from he elbow, which is a real shame..if yuh goin on tv to represent yuh company at least seem like yuh know na...


Was doin some wikisearching on CNG and I'll admit it actually sounds like a very good option...

Sutmbled on this though

Petronas, Malaysia's state-owned oil company, also monopolises the provision of CNG to road users. As of July 2008, Petronas only operates about 150 CNG refueling stations, most of which are concentrated in the Klang Valley. At the same time, another 50 was expected by the end of 2008.[11]

As fuel subsidies were gradually removed in Malaysia starting June 5, 2008, the subsequent 41% price hike on petrol and diesel led to a 500% growth in the number of new CNG tanks installed.[12][13] National car maker Proton considered fitting its Waja, Saga and Persona models with CNG kits from Prins Autogassystemen by the end of 2008,[14] while a local distributor of locally assembled Hyundai cars offers new models with CNG kits.[15] Conversion centres, which also benefited from the rush for lower running costs, also perform partial conversions to existing road vehicles, allowing them to run on both petrol or diesel and CNG with a cost varying between RM3,500 to RM5,000 for passenger cars.[


Given that Patos want to turn Trinidad into Malaysia kinda seeing where all his wonderful ideas coming from

Are they CNG kits for EFI vehicles?

[teems1]

^^

the Boone-Pickens energy plan is also to use CNG in the interim while the US switches to wind energy.

[wagonrunner]

Are they CNG kits for EFI vehicles?

of course there are Pete

Super is more environmentally friendly than Premium?

Ok... I suppose performance means more pollutants?

So only the 'top end' of the populace is allowed to pollute? Like these vehicles listed here? :

Must suck to have a 2.7 VVTi Hilux..

Must suck to have a 2.7 VVTi Hilux..

true. 4.0l Cherokee Sport back on super, still monitoring a few WOT runs though.

[wagonrunner]

Something i wanted to discuss, not sure if it's worthy of a new thread.

Since changing to super, ...........
I did clear the ECU's self-learn before i first put.
I have not changed my ignition timing, still 8° (I do get some pinging at 5700, but say on a highway run, it will only happen twice, as in 2 gear shifts, not enough to be considered consistent. but will still retard when i get the time)

.......... I have noticed lower engine temperatures.
Where the car would be a steady 83-85°C while the thermo is open. I'm seeing 74-80°C, a buddy says in his QG18 P11, where he would normally be at half or just above on the temp gauge, he's now just below.

Is anyone else experiencing / noticing this? and what could be a possible reason for it?

I've also seen Injector duty cycle increasing, and injectors opening for sligly longer, but that could be as the ECU hasn't had enough time to relearn since the switch.

Neither of us have done anyhting to our cooling systems just prior, or since the switch.

How ya checking those things? OBD-II Scan tool?

hmmmmmmmmmm try paying 4.00 us for a gallon of 85 octane gas nah.......
and 4.50 for 93 octane and when I want to go racing is 7 USD for 110 octane.................so stop your whinning and drive.......
untill you paying next to so unless you start paying 25 TTD for a gallon consider your selves lucky.................

BY the way gas does raise here if the wind in the ocean only blow wrong

[TriniVdub]

^^^ hold ur kant nah dred....we as an oil producing nation should not be compared to the states, but should be compared to venezuela, saudi arabia etc...now go look at what they paying for gas then come back and type what u learnt

So it's US$4.50 a gallon in the US. How much does that work out to a LITRE?

US$1.20 per litre, right? So dollar for dollar US citizens are paying less.

And even if you convert, you are paying TT$7.50 a litre in the US... where their gas consumption out-paces their production. And yes THEY are complaining.

Think relatively, my friend.

A doubles is TT$3.00 down here. And they paying US$3.00 up there. OMG! That's TT$19.00 for a doubles! We should be thankful of that too.

Typical Trini who is not seeing the salary side... Paying $4.50USD a gal when your salary is $4000USD is different to paying $2.50USD a gal with a hopeful $1200USD salary... and the average Trini not seeing that much at the end of the month. Common sense... Come nah man... Unless ziig making $13k+ a month... He real out ah timing there...

wagonrunner, what's the displacement and year of manufacture of your engine?

[wagonrunner]

How ya checking those things? OBD-II Scan tool?

you forgot i have the software and data cable for my car?
my ECU is plug n play bish.

Sample readings.............

djcarbon,
the engine im talking about is a GA15DE, date of manufacture of engine sketchy, but somewhere between 96-2000 by my estimate.
buddy's car who is experiencing this as well is a QG18DE, somewhere between 2000-2004

Would people stop quoting this frigging out of context article? The US measurement for octane is not the same as the British that use RON directly... The US use an average between RON and MON... So their 87 octane fuel, the "regular" gasoline in the US and Canada, is 91-92 in Europe. Period. Its not the same. Context is important. In addition to which in my humble opinion the falloff in performance for a 4L V6 is different to a 1.6L 4cylinder engine...

At the end of the day if our Super is supposedly 92RON and I find it hard to even believe that its basically barely 87 octane US grade... as far as clean gas we don't get options... there is no Shell or Chevron or BP gas station to drive to and compare so I doubt NP give a damn about us getting fed up of their quality and going elsewhere...

Ok guys, i found this on the net......

Do octane boosters really work?

When I asked Wusz his opinion, he replied: "If you start with an 87-octane and you put something in it, you might raise the octane slightly. When I worked in research we never saw any of the products work as effectively as they claimed." Let's say you're using a 91-octane gasoline and need more of a higher-octane cushion. Most people think adding octane boosters in the tank will raise the octane reading a few octane number percentages higher. Wrong buddy! Sorry to burst your bubble but you won't gain numbers anywhere near what the booster's manufacturer claims, because you're already starting out with a high-octane gasoline. The lower the octane numbers of the base product, the greater the chance of obtaining more octane. When you put an octane booster in an 80-octane gasoline it might be good for a 5-octane boost, but if you put it in a 90-octane it may only be good for only a 1- or 2-octane boost.

What are the advantages of using a high-octane race gasoline?

Vehicles with a higher compression ratio, using nitrous or forced induction will typically need higher octane. With racing gasoline, consumers demand the best of the best in fuel quality, especially when paying a premium at the pumps. "When we blend our Rocket Brand Racing fuels, we don't use any of the real light stuff. We chop the tail end off and then go forward, picking the goodies out from the middle," says Wusz. The main reason for using a high-octane fuel is it will burn quickly in the engine-you can't afford to have a slow-burn gasoline when your engine is turning 9000 or 10000 rpm. With any slow-burning gasoline, the engine will likely push un-burned hydrocarbons out the pipe, which is considered unbeneficial. The main focus for any vehicle is to have as much burn in the combustion chamber as possible. This maximizes the conversion of chemical energy into mechanical energy; it ultimately takes all of the potential energy and makes as much of it into horsepower as mechanically possible.

[djcarbon]

Yeah but the problem is that octane boosters don't work at all. The links to vids with tests were posted before... It seems that they basically dilute the fuel by about 2% vol. causing a -2% performance change...

http://video.google.com/videoplay?docid ... 2237&hl=en

It seems to be all in our heads... (yeah feel that? The car driving faster!!! (doh mind I mashing gas harder!!) In my mind? Nah boy it in mih foot!!!)

I didn't feel no diff in my 4G18 so I didn't bother... I know men faithfully butting two bottles in a tank and doh tell them otherwise...

[noshownogo]

ok so if we see no change at all with octane boosters and sometimes a negative performance change, what can be said about fuel injector cleaners? Do those work or is that also in our heads

[tr1ad]

ok dis go be a noob question eh


how yuh does kno when it pinging? is it a sound of "ping"?

[Greypatch]

dat self

[wagonrunner]

tr1ad,
nah, rattling like coins in a can

[Greypatch]

ignition adjustment

[noshownogo]

it sounds like fine gravel in a tin pan, had first hand experience with this

[tr1ad]

hmmm

when i had the subaru i tried super for a good few weeks, didnt hear dat noise


an no wagonrunner, it wasnt d diff bulb

[Greypatch]

dem ts could run on pitch oil man
