PapaBravo... i dont think the oil is the Culprit. Its possible na lumala lang talaga yung blowby ng makina.

I was victimized by similar circumstances... being a first time diesel user. Walang choice.... pina overhaul ko (twice in fact). But now im reaping the benefits of a good diesel engine! No regrets coz learning experience naman.

Frank::: Blowby is an engine condition where the engine oil "blows by" the piston rings and gets burned in the combustion chamber. Mapapansin mo to pag mabilis maubos ang langis mo... tipong 1 liter a week ang kailangan idagdag. Pansin ito sa gas engines, pag parang bluish-black yung usok, blowby na yon.

Sa diesel mas hindi halata kasi mausok talaga yung exhaust hehehe
