Duramax Diesel Question

Recommended Posts

GM/Isuzu have built well over 1/2 million Duramax diesel engines in Rayong. (Great Wall Motors have bought the factory and it would make sense that many more similar engines will be produced there.)

 

The latest version (3rd iteration?) of the 2.5 Duramax diesel with VGT (turbo) puts out 180 HP and 440Nm torque in the Colorado pickups. (30 HP more than the first version back in 2011.)

 

Does anyone know whether these engines made for Thailand are using DPF (diesel particulate filters)? They enable meeting Euro 4/5 standards by capturing soot while creating maintenance issues, and are required in many/most markets.

 

Fun Fact: The original small block Chevy V8 with optional 4 bbl carb also made 180 HP, but only 352Nm torque. (Ref:Motor Trend)

Probably of little help BUT... the V-Cross we had in 2012 did not have a DPF

Interesting, thanks. That is the first clue that maybe they don’t put them on the Thai models.

 

I am trying to get to the root of why there is no Dexos2 oil readily available, and even the dealers have told me it’s not needed.

AFAIK Thailand requires compliance with Euro 4 so Thai diesel pickups do not need to use DPF or SCR systems.  They generally use a DOC and EGR only. 

 

Some export models with DPF and SCR are assembled in LOS.

No DPF for local models.

THAT explains the blank looks I get asking around about dexos2 oil, which was designed to not clog up the DPF and other eco stuff! Thank you!

 

I picked up a Colorado for a song (8k km) and it seems to be a great truck. Wish they would have not put a dexos2 oil filler cap on it though! Shell put HX8 fully synthetic diesel 5w-30 in it, before I read up on what dexos was all about.

 

Big Thanks guys for clearing up that dexos2 is not needed for Thai Duramax diesels! 😀

Next diesel question actually applies to any turbocharged engine. Can anyone with direct experience tell me if installing an oil vapor catch can between the pcv/valve cove and the turbo air intake is a smart mod? 

 

This is my first turbo, and I plan to run it for many years. It seems like a really good idea to keep the oily engine vapors out of the turbo intake.

 

Any Duramax drivers using one?

With a Duramax engine, you don't need to do anything except change the oil and filters on schedule. It will run forever.

I guarantee you there is NO DPF  on the Chevvy Thai made  Colorado, I know as I messaged them before  buying, good  time to get one  now for the most discount, had mine 18  months,  no  issues at all one dealer <deleted> the other in BKK very good. This vehicle continues to be made in Brazil so parts  will not be a problem.

Its  getting a very minor  facelift in Brazil mainly front  bumper good  value now at 775k for the  top model. Lots of people who dont have one slag them off. I  love the looks and interior I tried  all of them and found many lacking in numerous  ways, Colorado suited me best

If you  look at Australia and America many do BUT I  think most of it is BS and the people promoting them are  SELLING them and they should  already have an oil air separator anyway.Plenty of old  ones around with 2-300k km on the clock

I can clear that up for you. Ok so for 2019 models and onwards they changed engine  oil requirements from 5w30 Dexos full synthetic ( good  oil) which i use to a 10w 40 semi synthetic also a c delco, the service intervals are 15k and 10k respectively, I think they did it to give dealers more work  and it works out slightly cheaper for the owners  long term.  dexos  2  is readily available and I use that , dont buy it from the dealer youll pay 500 baht  more

@bodga, thanks.

 

I wasn’t looking for a Chevy particularly, just a great deal on a good truck. Got a deal on a 2018 LT with 8k km. I also expect it will run a few 100 k with the way I baby my vehices. (6 speed manual to boot.) pretty sure the LT stands for Low Tech.

 

I am thinking to getting a local catch can, $30 on Lazada, an experiment in case it helps keep the turbo clean!

 

Chevy trucks are like what, 17% market share here? And the service centers are not closing.

That’s the plan, except I try to keep my vehicles like new, so I will be doing stuff!

Their  market share is tiny its a  very  much underrated truck imo. Id  use the DEXOS 2 as  stated in the manual also, its  not anymore expensive, but up to you
