Re: Why do pumps mix LPG with CNG occasionally? Quote:

I am paying for the full CNG tank yet what I am effectively getting is lower. Chances are that there is a lot of air mixed in the Gas(though the WR system detects and auto cuts off this) or there is a mix(which is sometimes displayed in CNG pumps) where you end up paying more for a lot lesser gas!!
Now, invariably, my first bar goes off in 10-12 kms which is not a great sign.
There have been times I have got over 225 kms in a tank full.
This problem doesnt really happen in pumps outside Thane though so I guess this is limited to Thane itself.
Anyone else faced this? |
Well, I got the answer to the query I posted.
There is a "mixed" CNG being supplied by MGL after checking with numerous CNG pump attendants.
If you tank up anytime before 8 am, the CNG is "pure".
Post 8 am, it is CNG having traces of LPG.
What this means to the end user:
1) Your car becomes hungry. When you get a tank full at 5 kgs in "pure" CNG, a mix would be at 5.8-6 kgs.
2) The fuel efficiency takes a drastic hit. I invariably get a FE of 22+ kms/kg on my WR. Now, of late, I am getting nothing more than 19 kms/kg
3) Dont know if this is true or myth, mixed CNG helps clean the carbon in the system.

The problem is happening since the last 8 days or so.
Hope we get a resolution soon!!! |
