Does Synthetic Oil improve Diesel/CRDi Engines

[jackbauer]

diba para mas ok pa yun Shell Diesel kasi nababawsan naman daw ang oil anyway in between PMS?

what do you think?

magastos kasi pag synthetic, parang wala naman difference sa performance

[washburn]

calling sir DieselDude sir any significant changes if nagpalit ako ng full synthetic sa CRDi engine ko? advisable ba? mag 15K na ako at nagiisip akong mag full synthetic thanks

Frankly, I don't know. But my position is to always use the recommended oil as stated in your owner's manual. If your manual doesn't require you to use synthetics, then don't. Dagdag gastos lang yan.

By the way, is your car a Starex CRDI? What does your manual say?

santa fe,
Im looking it right now, wala naman nakalagay they just recommend to use Shell helix motor oils
by the way sir anu yung CPF (catalyzed particulate filter) ? ito ba yung catalytic converter?
thanks for replying

sir naki-post lang pala ako kay TS (jackbauer)

I saw one starex CRDi in Hyundai Alabang using Castrol Magnetec during oil change. Sabi ng mechanic ay ok daw yung magnetec dahil tahimik ang engine. Tried and tested na raw ng mga customer nila yun.

OT: sana yung TS(jackbauer) ay hindi utol ni Eddie Bauer. hehehe

On the power increase, on well-tuned engines with mods and tight tolerances there can be a power increase with synth.

For me, the main upside to using synth, esp. on a turbocharged engine, is protection as it lubes better during cold startups and is also less susceptible to break down under hard heat conditions.

I have a friend who's been using synth oil on his 1992 Sentra since he purchased it 2nd hand in the mid 90's (40K on the odo at that time); now it's ran well over 220K kms and his engine is still running healthy compression and has never been opened up.

OT din: Hindi mag-utol sina jackbauer and eddiebauer, dahil iisa lang sila (alter-ego ni OB/newblue/bladerunner, etc)

I just talked with a Hyundai service manager friend. He recommends 15-W40 multigrade oil from any of the big three: Petron, Shell, or Caltex. Synthetic is not necessary.

He also told me that all current Hyundai CRDI engines have catalytic converters. Very good emissions!!

In my expierence naman, Isuzu does not recommend any other oil except IGMO SAE 40. Even its Mobil SAE40 counterpart. Specially formulated daw ang IGMO sa products nila na presyong synthetic naman.

If hindi naman required I dont see the need for using full syn.
Unless you have a hydraulically activated electronic unit injector.
Which oil quality and consistency is critical. Like what Dieseldude has been explaining, the 4JX1 is a diferent type of fuel system which requires a specific type of oil. It has a rail/plenum but oil is being pressured and not fuel like most of the CRDI.
