Sir Dieseldude,

1997 Hilux 2L engine. 347xxx kms. 5k kms oil change interval. laging bosch oil at fuel filter. every 5k kms linis ng air filter, every 30k kms naman ang palit (replacement)

napapansin ko sir kapag under load or kapag mag aaccelerate ako, may buga ng black smoke, kapag Euro4 diesel ang gamit ko, less smoke lang pero meron pa din.

kunyari sir, sa highway, constant 90kph walang black smoke, kapag mag oovertake ako from 90kph to 100kph, may buga na, pero kapag nag constant 90kph or 100 kph or any speed, wala naman usok.

ano po kaya kailangang i-check? matipid naman sa diesel, wala din oil consumption.

kailangan ko na kayang magpa check ng injectors? ok naman sir yung acceleration at idling niya, may konting usok lang kapag aarangkada.

Salamat Sir

Sa palagay ko normal lang yung konting smoke during acceleration dahil Euro 2 ang engine mo. Mas malinis talaga ang emissions ng mga modelong engines.

Pwede mabawasan ng smoke yung 2L engine mo through pump calibration. Magkakaroon ng slight improvement ang fuel consumption mo, pero mababawasan ka ng konting torque.
