However coilpack were going before as I realised there was slight misfire with cng but not with gas. The cng is precise and shows up any weak areas in your engine e.g. overheating. All my mounts were bad due to jerking until I regapped and cleaned maf and throttle body .



So
Regap your plugs between 0.8 to 1.1 terrific acceleration under cng
Clean your maf sensor and throttle body
Change plugs
Very important. Don't be cheap and use super gas. Run the premium and enjoy cleaner internal and injectors . When using cng and your injectors just dribbling to maintain idle super IS going to clog it and affect idle issues and performance

I have qr20 engine. I am due to service and car running excellent. I informed my neighbour about the gapping after he waste money twice on changingToyota coilpacks and plugs

What plugs u use...I have a problem with getting the right plugs for my mr20 engine fitted with cng 341 3654

Typically they use a colder plug.
Stock is a 6 heat range in NGK. Just change your plug from 6 to 7 and look for that. May not be a plug found locally and might be an import item.

The best plug to use is a copper plug but for some cars given what is entailed in changing it doesn't make sense to even consider putting in anything cheaper than platinum.

Time to refuel?
Check out the current listing of public CNG stations where you can refuel.

Has anyone itt left the cng thing entirely or simply abandoned the idea of procuring a cng vehicle? Does any current owner have any regrets or noticed issues worth mentioning?

Wasn't the Barataria station a CNG equipped one? Haven't paid attention to see if the pumps are still there.

I saw this post being shared around,

“Good day. I am CUTT member Peter Laltoo, #00987.

I converted my vehicle to use CNG about 8 or 9 years ago. The job was done by automotive components (massy motors) in Arima. It cost about $12,000 back then.

Each garage typically can only service the system that they installed. They usually do not have the tools to service a cng system from another company. Software in particular is an issue (yes the cng system is computer controlled).

Imagine my shock when I called automotive components last week to schedule a service, only to be told they no longer perform any sort of cng service or repair. For reasons best known to them, that portion of the business is now closed permanently. The massy rep did give me a number for a private individual who MAY be able to service the system.......but when I called...he indicated he did not have the software required to adjust etc.

After all the guava-ment talk of cng....I am now left with a non functioning system.....that apparently NOBODY can service or repair.

Way to go......”

CNG was never a good long term investment.
Thats just adding a plaster to a sore.What we need is a cheaper electricity alternative and more efficient EVs.Before Zoom chimes in about 'carts', drink your coffee and mind your goats.

The biggest issue with CNG or LPG is distribution. CNG does lower emissions but does not drastically lower emissions. For commercial and maritime large displacement engines, CNG makes for a positive environmental and financial choice. CNG for personal use? Not so good a solution.

I recently installed a cng kit. From less than average 2km per dollar on premium gasoline ($7.75/litre) to around average 12km/$$ (or litre) on cng. I do hope the cng price doesn't increase or remains $1/litre. I turn off the cng and use pure gasoline when the additional power is needed (i rarely do this). I rather cng atm since my knowledge on electric vehicles is limited. I can easily diagnose issues without going by a technician who can probably trick me into paying for unnecessary services.

2014 hyundai tucson (gasoline). Cons worth mentioning: less trunk space due to 70l tank. Additional weight on the rear (rear slightly lower) Not much people notice it but I do. Cost alot to instal with the hope I get value for $ in the long run by the price remaining low per litre.

Calculate your average yearly milage should not be to difficult and then the total gas you would spend then consider ratio gas to cng in percentage you will be using. Then get your payback period

That could be as much as five years

Hope your vehicle holds up for that period

If you get in accident or need major repairs and have to sell you will have lost money

Remember all during the payback period you will be in the red

In that calculation, doesn't he/she need to factor in the tax credit that he/she would be entitled to for the year in which the system was installed?

12km/$ CNG and 2km/$ Premium is 8.3¢/km CNG and 50¢/km Premium

Assume the average cost of conversion is $15,000 and maximum tax credit is $2,500.

The average driver travels 20,000 km/yr, with a less frequent driver travelling 13,000km/year and more frequent driver travelling 27,000km/yr

An infrequent driver will have a payback period of 2.8 yrs or 2.3 yrs with tax rebate.
An average driver will have a payback period of 1.8 yrs or 1.5 yrs with tax rebate.
A more frequent driver will have a payback period of 1.3 yrs or 1.1 yrs with tax rebate.

edit: a five year payback period occurs if the OP is driving 5200km/yr (3200 miles/year).

i find we should get a tax credit for hybrid cars too- yeah it's tax free but the dealer taking a lot of that so the benefit to the consumer is reduced.

Are you assuming he uses CNG 100 percent of time

Doubt that will be the case

People generally get fed up going gas station every two days

Used a Honda City recently and got 226km from it using CNG. Went to fill Mon Repos and that was $12 from empty. To me that’s damn good

I only used cost information provided by the OP.

OP also states that he has a 70l tank with 12km/l fuel economy (840 km/tankful).

A refill each time 1/4 tank is reached, equates to driving 630 km between refills. For the average driver (20,000 km/yr), that's 32 refills each year. A more frequent driver (27,000 km/yr), needs 43 refills per year.

OP is likely to need three or four refills each month, assuming a typical user profile.

Thanks for all the feedback everyone. Yes I use cng all the time now. I used to put average $330 premium gasoline every 5 to 6 days. I live central (refill stations nearby) and I always keep topping up the tank (daily) to avoid running on gasoline. I only use gasoline for engine warm up and sudden high acceleration etc ( barely use it at all ). I badly need to make this investment work .

I only use gasoline for engine warm up and sudden high acceleration etc ( barely use it at all ). I badly need to make this investment work .


Question: People with CNG systems allow the cng to run out for long periods & are comfortable consuming gasoline? That defeats the whole purpose (my opinion). I get more km/$ on CNG, why waste money running on gasoline? My trip distance tally (reset only @ every gasoline fill up) is over 900km (more than 1/2 tank gasoline remaining) since the last full up of gasoline. The CNG was installed @ 3/4 tank of gasoline and only about 200km (not too sure) was done before the cng installation.

What's the reason for using gasoline over the CNG (other than better performance)??
Kindly enlighten me.
Am I doing something wrong???
Will I still damage my engine despite being light on the pedal while on CNG??

Average Daily cng used = $8= 88km. So 8×365= $2920/year. Today was average driving throughout the year on cng only all day.
88km @ less than 2KM/$ Premium gasoline ($7.75/litre) =
more than $44 daily= more than $16060 yearly.
16060-2920= >$13140 saved end of year running on cng only. Doesn't include additional maintenance due to cng system nor tax credit. Hitting Manzanilla weekend from central. Topping up the tank at tumpuna road arima to and from. Cng throughout from now on. So even more savings per year by avoiding premium gasoline. MAJOR DRAWBACK IS FREQUENT VISITS TO TOP UP BUT I RATHER SAVE $ MORE THAN TIME.
