No special procedures involved, para ka lang nag oil change. Sa akin I use the diesel motor oil up to my next oil change schedule, yung sa iba up to 500 to 1000 miles lang.

Okey naman, malinis ang engine at smooth ang takbo. I have been doing it for about three years now. Yung iba nga have shifted to diesel motor oil totally to lube their petrol engines.

Havoline (dati havoline energy ngayon formula na lang) and Delo Gold ang gamit ko. No appreciated performance difference sa dalawa.

Yung ibang gumamit ng engine flush biglang nagkakaroon ng leaks sa mga engine seals.
