Assalamu Aalaikum Wr Wb,

Mods are most welcome to delete this thread if it sounds too redundant. With that being said, I'd like to share a small experience of mine with the readers here about my first experience of hypermiling with CNG.

I had Pajero Mini that I sold about two months ago. And last week I bought Suzuki Alto (Pakistani) 2007 with factory fitted CNG and AC in original condition. It had about 75,000 Kilometers on it so its a farely used car.

Two days ago I went from Peshawar to Jhelum. I filled the cylinder at Pubbi (its about 20 KMs from Peshawar I think) and then refilled at Dina (10 KMs before Jhelum). I obviously had the odo meter reset when I filled the cylinder. So I got 260 KMs when I was filling again with 100% non-stop AC (at 1x fan speed).

On my way back, since it was a CNG Holiday (yesterday -- thursday 19th July 2012) -- I filled from Khariyan and drove to Islamabad (blue Area). From Blue Area to motorway and till Peshawar. It was a trip of 325 Kilometers (with 0% AC) and NO refilling so far. When I reached home it was showing 1 green light. But today when I started the car it turned red. It does about 20 - 25 kilometers easily on the reserve light.

So here are the stats in short:

260 Kilometers in 1 Cylinder with non-stop AC.
325 Kilometers in a little less than 1 cylinder with no-ac.

I think it would easily do 350 KMs if I had more journey to travel. Both are averages I got on highways. Speed was around 70 - 95. Mostly it was on 80. Because if you keep anticipating the road, its really not possible to cross 80 on the GT Road.

According to today's petrol price, this above mentioned average turns out to be about 49.6 Kilometers/Liter if I had covered the same distance in petrol (by spending the amount of money spent on gas).

I wonder what exactly is wrong with CNG and why are so many people against it.. Just the other day I was reading somewhere on Pakwheels that Alto was discontinued because of it not being complaint with Euro 2 emission standards.. but one has to think how many altos are running on Petrol at the first place? Which Euro Standard accedes the greeness of CNG?

What are your views guys?

I believe thats the best mileage i have seen from an Alto !
Were you driving normally or hyper-milling ?

Wow! Somehow there is an impression here on Pakwheels that Alto is a small guzzler, however your statistics are very impressive.

It was bumper to bumper hypermiling

matlub full 100% hypermiling. Slow Acceleration, anticipation on the road. Avoiding breaks and shifting to neutral by way before coming to a stop. That's all there is. I had a very very light foot on the accelerator. Infact, it was almost 'not pressed' very very lite, but the speed was good enough. I also noticed that Alto has a better rolling than other cars that I had (City and Pajero Mini). So shifting to neutral really gave a long enough break to the accelerator which is really nice.

I did also inflate the tyres are 35 PSI. Next time I'll try 40.

This is my car's CNG consumption worksheet:

@poster

bro just for the sake of saftey of urself and others around plz dont refill from the pumps again from whose top ups you got such outstanding mileage. period

awais.9 (awais Khalid ) 2012-07-20 06:12:20 +0500 #12

@^
its not about the pump
its about super hypermiling

This is Hypermiling:https://www.pakwheels.com/forums/performance-modification-tune-up-preventive-maintenance/143083-hypermiling-getting-unbelievable-mileage-petrol

Both averages were WITH hypermiling. The difference was only of A/C.

I cannot understand your periods. We didn't mention any thing about any pump anywhere in this thread.

Welcome back sir
you are back with a bang!
Setting another milestone for us-the student hyper milers

dms664 2012-07-20 07:43:18 +0500 #16

alto is fuel guzzler on petrol only. On CNG its a gem.

BilalYusrat (BilalYusrat) 2012-07-20 08:22:42 +0500 #17

Jazakallah Khair brother, may Allah reward you for all the appreciations. What are your averages on Petrol/CNG recently?

Alto has good millage in Long Routes !!
mine ALTO returns me 250 km in one cylinder with 30% A/c (mA)...

my city already giving 230 with fultus AC on moterway. i drive between 100-110. means i m already on
hypermiling

thats on the filling of 8.3 KG full cylinder

dms664 2012-07-20 09:31:40 +0500 #20

Sir in peshawar local commuting I cant cross the 12km/l mark with all hyper miling techniques applied, come what may (with AC). I don't know fault lies at my end or the congestion of roads, traffic in peshawar (1.3 L 2nzfe)

ma sha Allah On long I have achieved 210 km with 90% AC on 60L cylinder (ac was switched off on ascends)
That is my best score on cng till date

On my way back following the same route as mentioned above used petrol all the way and it returned me 15.5 km/l with ac full time. Dont know if its a good score or not for a 1.3 l 2nzfe vvti with 4 passengers plus luggage

avg speed was 100km/h

Sir I wanted to ask if the ac fan speed plays any role or not? I usually keep it on 1 when traveling alone but if accompanied I keep it on 2 not more than that but then I do not switch it off again n again. It remains on all the time.

I have seen ppl keeping it on 3 or 4 but then switching it off n on with regular intervals. please put me wise regarding this.
