Hi,
Need advise on where to get the CNG cylinder checked. Its about five years since the installation.
On last tune-up the mechanic drained oil from CNG kit and suspected that there may be oil in the cylinder too. According to the mechanic draining the oil from the cylinder, and reviewing its oil condition will tell the condition of the cylinder. [If oil contains particles it means the cylinder is deteriorating otherwise its fine]
Need suggestions on a proper facility and method to get the cylinder checked.
Thanks.
