CNG yapamwamba kwambiri imagwiritsidwa ntchito m'malo opangira mafuta chifukwa champhamvu kwambiri pakuyaka. Chifukwa nkhokwe za gasi wachilengedwe zikuyerekeza kuwirikiza kawiri zamafuta, ndizotsika mtengo, zimakhala ndi kuchuluka kwa octane, komanso kutsika kwambiri kwamafuta owononga mpweya (CO) poyerekeza ndi dizilo kapena petulo.₂ palibe_x 25% ndi CO zili mpaka 50%), zitha kufotokozedwa ngati mafuta osamalira zachilengedwe komanso odalirika.

Chipinda chaching'ono chonyamula katundu chifukwa chokhala ndi thanki ya LNG, komanso netiweki yaying'ono yodzaza malo, zimalepheretsa kukula kwakukulu. Kugwiritsa ntchito galimoto zamafuta achilengedwe kumawonetsedwa mu kilogalamu pa makilomita 100, pomwe magalimoto wamba monga Renault Scenic, Fiat Doblo kapena VW Passat, omwe asinthidwa mufakitole kuti ayendetse, amagwiritsira ntchito gasi pakati pa 5 ndi 8 kg. .. . kwa 100 km.
