Kamusta po idol DieselDude...
Dati po mausok yung Fieldmaster lalu pag sudden acceleration, pina-tuneup changeoil palit bago air/fuel/oil filters ganun pa din. May mechanic po nagsabi sakin na posible din daw na nasa quality ng diesel kaya mausok madumi daw diesel natin sa pinas, example pa nya may mga bagong montero nga daw wala pa plaka mausok na. Madaming montero sa kalye......hindi naman sila mausok.

After browsing some forum, nabasa ko po about Euro4 and Euro5 compliant Diesel fuel which is cleaner daw. Ang nabanggit po is Unioil Euro4 and Seaoil Euro5. Big3 is Euro2 only.
Kaya sir, tried Unioil, after a couple of Fills with unioil napansin ko very less smoke na nga kahit sudden acceleration or pataas ang daan need to step more sa pedal di na nga mausok. That's good to know. Nag improve din ba ang power?

Question ko po, totoo po ba na posibleng by using cleaner euro4/5 compliant diesel e mawala ang emission ng black smoke or nagkataon lang yung experience ko. Hindi ko alam.

Another question po, I read na euro4/5 diesel has less sulfur that can adversely affect older diesel engines due to lack of lubrication etc, totoo po ba to sir? Less sulfur means less lubrication. But it depends on the formulation. I haven't really studied this matter.

Or safe naman ikarga euro4/5 ng unioil seaoil diesel on older engines as is without adding 2T. I don't know. But I'm quite sure that these new players have studied their fuel's applicability to our market.
To counter this naglalagay din po ako ng 2T oil 200ml/50L mix po, so far so good naman, lesser vibration and better response. Wala po ba bad effect ang 2T oil sa older diesel engines like 4m40 fieldmaster? Di ko pa naaral ang effects ng 2T oil. Pero kung ganyan mix ratio, palagay ko okay lang.
Thanks MasterDD in advance!
