2020 Silverado With Duramax 3.0-Liter Diesel MPG Revealed (Better than Colorado Duramax)

The problem RAM has is their gas trucks's payloads are ~1400lbs, where similarly loaded GM is ~1900.  RAM is adding a compacted iron block (heavy) and Chevy is adding aluminum (less heavy).  It's not too hard to see how this ends unless RAM significantly bumps up the GVWR for the 1500s with the eco diesel.

I had a 2014 dodge ecodiesel 4x4 1500 with 8 speed transmission. I loved driving that truck and got great fuel economy. But, RAM killed us on oil changes. 10 litres of very expensive special hocus pocus oil and a 60$ filter made it a $350 oil change every 10k miles. I did it myself after warranty and saved a bit. Then the tranny needs special oil too and a filter built into the pan so you had to replace it all and they wanted $1500 for that. The a thing called an EGR cooler in the exhaust system went at 120,000 miles and was going to cost $2,000 to fix, and they said the coolent leak probably damaged the Cat and that would go next at $4000. I traded it on a 2018 Siera 5.3. No turbo, no special tranny, I pay more in fuel but not in service.

 

Unless you are going to go a million miles, or you tow a great deal you should look very closely at the numbers and especially check out the service costs before you pull the trigger. 

 

GM may do it better than RAM, I'm just saying, check it out first.

Still don't see these numbers on the EPA site.  Anyone know when trucks show up in showrooms?  Was hoping this would spur the next round of reviews being approved for release.

Trucks will be put 8 weeks after EPA signs off on emissions from what I was told bun GMC dealer. They can take order but trucks won’t be built until certification comes.

Thanks for sharing it's stuff like this that holds me back on Diesel.  I have 5.3L Ecotec3 and is about the easiest thing to maintain plus it's never failed me or cost anything other than a AC compressor?  If I can get that from 3.0L Duramax with minimal maintenance costs I am ALL in but skeptical no doubt!

I'm hoping GM does do it better than RAM - definitely going for an extended warranty.  The problem for me is the 5.3/6.2 have puny tanks for towing at what they burn while towing.  So it's either this engine, an F-150 with a 36 gallon tank, or 3/4+ ton trucks.

The tank size should have been 4-5 gallons bigger.  The 3.0 will do just fine on 23-24 gallons.  I did recently check out a 2020 HD with Duramax and was blown-away!  80K blown-away but what serious frigging rig!

I was blown away by their decision to not put adjustable pedals or adaptive cruise in it.  With the higher hood line and no adjustable pedals, it won't work for my wife.  So now it's basically between the diesel 1500 (barely works without adjustable pedals), RAM HD, or 2020 Ford.

Let's just hope the new 3.0 Duramax proves to be as reliable as it is efficient.

Anyone know if this engine has been tested for a while overseas before being introduced in Canada or here in the states?

143 HP less than the 6.2... that one hurts my pride a bit. Same torque numbers though. Basically, the MPG increase is the only attractive selling point for this motor.. I can't wait to drive one to see how it feels.. maybe my next truck. 

But after a quick tune, I'm sure these numbers will go way up.  This will be my next truck with that Duramax in it.

 

The Ram Ecodiesel has a tune from PPEI that will add 60hp and 114ft lbs of torque.

 

The 3.0 power stroke has tunes that will add 40+hp and 100+ft lbs of torque.

Good point, but I'm afraid the ECM tuning restrictions the 17+ 6.6 Duramax has (and I'm assuming the new 3.0L ECM) will drive the cost way to high for tuning.

So ... always an interesting topic - gas vs diesel.  Have had lots of diesels cars, but no diesel trucks.

 

I get why diesel is desired for big trailer loads ...especially if hauling often.

 

My 2017 Silverado with the 6.2 (8 speed trans) gets better than 24 mpg if I stay between 70-75 mph.  At 65 it is around 26.  80-85 it gets around 20-21.  Hauling a 7000 boat it gets 10 mph at 70-75.

 

Given the cost of diesel, the increased oil changes, the increased complexity - I can only surmise I would want one if I had big, heavy consistent loads to pull.

Sure, but it's made by FCA....

Put this in a ZR2 with a bigger tank and you have something that can go much farther than a raptor ever could even with a truck bed of Jerry cans.

Trans flow and titan make upgraded tanks for the power stroke F150. 50+gallons should do. Hoping they make it for the dmax 1500

      Hi everyone,
       
      So since my purchase of a 2016 Silverado 1500 in May the main problem I've had with the truck is its inconsistent ride quality. The truck is a WT with power windows and locks. Cloth seats. And vinyl floor.
       
      The truck only has 27000 miles, well kept and maintained. Used as a commuter truck to work, aswell as work on the side (Electrician). Truck was purchased with only 22000 miles on it. No issues other than leaking pinion seal which is in the process of being fixed. 
       
      At first I thought it was the tires so I had them balanced, rotated, and had an alignment done. While that helped it didnt fix the issue at hand which is how hard this truck drives
       
      It's a very uncomfortable ride at all speeds. Even on freshly paved highways and roads it still drives rough. What defines "rough" is the hitting of minor bumps. It can be just an ever so slight crack in the road to minor pits. I've done some testing and drove another vehicle (An f-150) down those same roads and had no where near as much of a impact and hit as my own truck. Now it's not a major impact like hitting something that you really shouldnt. But it's very unsettling and jarring at times as you would be driving the same roads you have been for years in different vehicles, and when you least expect it feel a nice jolt in your back when you usually wouldnt. 
       
      If you need more understanding, put a handful of change in the compartment under the AC controls and drive around.
       
      I was wondering if it has anything to do with the stock suspension that comes along with the truck. Should I try out new shocks? Is there anything else I should try? I have no clue what to do and where to start but driving 45 minutes to work with the truck makes my back hurt as much as after an 8 hour day of work. 
       
      Thanks

      GM recalls 160,000 pickup trucks in Canada for fire risks, nothing announced in US yet
      As of right now there is a recall for all GM 1500's years 2014-2018 that have both a rear window defogger and a power sliding rear window. 
      https://www.cnet.com/roadshow/news/gm-recall-pickup-trucks-canada-fire-risks/
       
       
      That recall has not been expanded to the US.
       
      I Just got off the phone with GM and filed a request to have the recall expanded to the US. I would encourage everyone who this applies to in this forum to do the same. It takes about 5-10 min but could save us all a lot of hassle later. 
       
      HAVE YOUR VIN READY
      Call GM @1 (866) 522-9559
      Reference this recall number:
      Manufacturer Recall Number
      N192220470
      (This is the recall number from GM in Canada)
      (reference: 
      https://wwwapps.tc.gc.ca/Saf-Sec-Sur/7/VRDB-BDRV/search-recherche/detail.aspx?lang=eng&mk=0&md=0&fy=0&ty=9999&ft=&ls=0&sy=0&rn=2019325&cf=SearchResult&pg=50)
       
       
      They will tell you that the recall only applies in Canada and not to your VIN. 
      Express to them that the recall needs to be expanded to the US since our vehicles are also affected. 
       
      Please post here if you have called GM (just so we can keep track) 
      Please also post if you have experienced this issue (smoke, glass breakage, etc) 

       
      Affected components: electrical – rear window defroster on trucks equipped with the power sliding rear window.
      Affected vehicles:
      2014-2018 Chevrolet Silverado 1500 2015-2019 Chevrolet Silverado HD 2014-2018 Chevrolet Silverado LD 2014-2018 GMC Sierra 1500 2015-2019 GMC Sierra HD 2014-2018 GMC Sierra LD  
       
      It may be a good idea to sticky this topic.
