Salamat Olive Drab and Doc Diesel,

After searching the internet mukhang possible nga yung pinuno muna ng oil treatment. I saw sites of oil lubricants claiming to minimize or stop blow by thru their oil treatments, like Valvoline.

My next question is okay lang ba kung gagamitan ko ng oil treatment to stop the blow by. What's the downside to using them? Or should I go for more drastic measures such as overhauling na?
