btw, start ko palagi ng engine set ko sa petrol then after couple of minutes switch ko sa gas... sometimes pag mainit pa ang engine, gas nalang kasi sometimes hard start pag gas...
What do you mean by this? Do you mean that it is hard to start the engine with lpg when the engine is cold but starts normally with lpg if the engine is already warm? Does the engine shudder when you switch from gas to lpg and vice versa?

Do you need to inform/register with LTO that you converted to dual fuel? Will the conversion affect your insurance policy? How do you maintain the LPG system?

I am seriousl considering converting, kaya daming tanong. Thanks in advance.
