I just had my change oil last Christmas break (3 months ago) and when I had my fuel refill, the gasoline boy asked me when my last oil change was. I was surprised to get asked this question and he showed me that the oil was already dark.

The oil i purchased and used was the best Diesel engine oil Mobil had to offer. The 6L of fully synthetic Mobil 1 cost me around 5k.

(4d56 engine)

Ano kaya ang problem?
