Subaru Levorg

Hi everyone, anyone had any issues with Direct Injection?

 

any carbon build up in the engine valves and crankcase?

Normal.

 

Juz do walnut blast around 100k km.

Great info!

Wow I didn't know Subaru/Toyota uses both port and direct injectors. I thought only high-end cars uses dual injectors.

Do not worry about this. Use good quality oils. The engine can easily last you the life of the car

ya... so much horror stories online for DI

 

saw a reply from Subaru:

 

 Older direct injection systems that experienced carbon build up were so called “lean burn” systems. Unfortunately these systems suffered many times from uneven combustion due to variations in the fuel and air mixture throughout the combustion chamber. This created a mix of lean and rich conditions resulting in variations in combustion temperature and uneven burning of the gasoline. This uneven burning lead to the condensing of unburned and partially burned hydrocarbons which over time resulted in carbon buildiup.

 

Subaru engineers understood this when they created our current direct injection system. They developed innovative yet simple systems to manage and control the combustion variations inside the combustion chamber. These include features such as specially shaped piston crowns, multi-patterned injection spray, and tumble generator valves. All of which promote the precise swirling and intermix of fuel and air under the variable conditions required across the full range of power requirements. When combined with very high fuel pressures and extremely short injection duration of the Subaru direct injection system, stoichiometric combustion is maintained across the combustion chamber resulting in very even and complete burning. As a result abnormal residue and carbon deposits are not created and engine performance and fuel economy are maximized.

Please note that our research does show that routine maintenance, per the warranty & maintenance booklet, is another important factor when avoiding any potential carbon buildup concerns.

Plead do not scare yourself. Many online theories but not everything online can be trusted. Subaru is not a fly by night car company . Have faith in it. I repeat myself. Use quality oils and the engine will last the car life

Stop comment on this topic lah.

 

It has nothing to do with quality of EO.  Go & read up on the use of catch can.

Which workshop provides this service?

[inlinesix]

Which workshop provides this service?

 

Those that service German cars, Audi, BMW & Merc.

 

Maybe MBM.  As Audi uses Di much earlier than BMW & Merc.

Why dun manufacturers install an oil catch can? I wonder...

Cost?

 

Maybe.

 

Even catch can is installed, there is no guarantee that it is trouble-free.

Oil catch can is a cheap mod. Some of my friends VTA

Cause oil catch cans need to be emptied out every few thousand kms. It is one more thing to maintain and most consumers can't even remember to change their engine oil regularly.

Just did a quick search for a friend on SGCarmart and realised there are 8 used Levorgs on sale. Any problems faced by past or current owners? 

[Nitroxdevil]

Hi, just got myself a year old used Levorg.

 

anyone here replaced the HU to Apple car play/Adnroid Auto capable HU? 

Brand and models?

$?

 

Thanks.

[Soonkuay76]

Oh my the 2.0 version is like $178K!!!!

Am looking for second hand for this quirky fella of a car

 

AD price is $140K

 

Looks like second hand is the way to go

 

To current levorg owners

where do you guys service your car and how often?

 

Saw MI package pricing a little bit high side though
