Does the consumption reduces in winters? I installed CNG kid early dec 05 and the first cylinder (45KG) gave 140 KM approx. After that it kept on reducing and yesterday i got only 90 from the same. I got filled the cylinder last night at 11.30 and the gas pressure was very high. But in the morning I was surprised to see that the pressure has dropped. The gas station is hardly 1.5KM away from my home. There is no leakage in the KIT. Any idea wht's goin on with a brand new kit and cylinder.
