Mga Sir;

Need your help to give us idea.

Kung mag papa change oil ba, is it better to use first the engine flahsing oil... please correct me if I'm wrong.

Can you advise how to use this in correct procedure...

Makakatulong ba ito para malinis loob ng engine bago i fill up new engine oil,
lalo na those soaked in flood.?

Please help me ......

thanks/
