天然气气瓶属特种设备，除生产厂家必须获得国家相关部门批准资质外，气瓶的体积、材料、厚度等都要严格遵照国标。同时，气瓶在出厂前会经高温、抗压、防爆等多项检测，安全系数较高。瓶体上有安全阀和防爆阀，安全阀的主要作用是在气体出现超过安全压力的情况下，阀门能自动释放气体。而一旦撞击力度超过瓶体设定力度，防爆阀会迅速打开让天然气在短时间内自泄。另外，在一定压力、撞击力等因素的作用下，瓶体自身还具有“撕裂”功能，从而确保安全。

眼下，“油改气”技术比较成熟，除了较高档缸内直喷式汽车，市面多数燃油汽车都可改装。改装后的汽车能实现油料、天然气自由切换，不会出现燃料混烧情况。相比过去手动切换燃料，当下通过安装行车电脑还能实现自动切换，一种燃料用完后自动切换另一种燃料。

天然气燃烧更充分，积碳也少，能减轻发动机的磨损，延长其寿命。济南汽车油改气美中不足的是，启动或爬长坡时，一些习惯驾驶燃油汽车的车主可能感到车的“劲儿小”。
