I'll start:
My vehicle: Starex grx 2007 crdi (non-vgt)
Odometer reading: 69,990+ km.

1. Changed air filter mga 1 week prior to the test.
2. No change oil yet. My engine oil has run almost 5k km already. Been using delo gold ultra and bosch oil filters for the last 15,000 km.
3. Been using PTT diesel fuel for the past 6 months (me price discount ako kasi and it has 1% or 2%(?) biodiesel formulation, not sure). Once in awhile sa petron and caltex kung emergency, pero very seldom.
4. No water hose treatment on the exhaust tail pipe since my rig has a catalytic converter.

My passing score taken yesterday: 0.35 (CMIIW, the passing mark for turbocharged diesels is anything below 2.0).
Last year, it was 1.7 (odometer: 54,000+ km) before I began using the items in paragraphs 2 & 3.
sa gasoline engine ng civic 96 and revo 2001 and ginagawa ko lang ay change oil, change oil filter, change air filter ang change spark plug. then pa emission test na, parati namang pasado. 2x a year a ko pa ganito.
