What's The Most Fuel Efficient Truck? 2020 Silverado vs Ram 1500 Diesel MPG Shootout! 

A most excellent comparison! Good job guys.

Imagine if vehicle manufacturers didn't have to worry about vehicle exhaust emissions so much, to have only the regulations from 1996 but now have this amazing fuel saving technology, we seriously could get 40+mpg from diesel engines in half ton trucks.

I have a 2018 crewcab ecodiesel with 4x4 and 3.92 rear end. I pull my travel trailer Aspen Trail 28bhs , unloaded 6900lbs maybe 8000lbs full with family. My average speed are 60-65 mph and i do 13 mpg !

I just ordered a '21 Silverado RST with the I6, I can't wait! Great vid, guys!

Mr. Truck's vest is like a super hero cape.....

I recently turned my 2020 Chevy 1500 crew cab with the 5.3 v8. I used the truck to tow my 7500 pound boat and got about 7-8 mpg while doing so. Got the 3.0 duramax and that pulls better than the 5.3 and gets around 13-14 doing almost 80. Been nothing but impressed with truck and no problems to report with almost 18000 miles on odometer. I mainly lease but this is the first truck I might buy!

I love these tests you guys do it helps out tremendously without having to look through and find 100 other reviews that are legit keep up the great work guys!

This is probably the best and most accurate truck to truck comparison you guys have done. Great video guys.

Andre: I'll give you the nozzle Mr. Truck! Mr. Truck: (enthusiastically) Thanks! I love this greasy oily thing! This review was good. GM did a good job on the diesel based on the reviews I've seen on other channels etc.

So far the best 2020 Silverado vs. Ram video's I've seen on the new 3.0 diesel engine 1500 trucks!I can't wait until they release the Ike towing results between these two trucks, great work TFL truck!!

That is phenomenal fuel economy for a full size truck. Is there any chance you guys can test the 4X4 variants of these trucks with the diesel engines?

I would love to see a 3/4 ton diesel vs 1/2 ton diesel on the same conditions, comparing max load on the 1/2 on each truck. Might help some of us who are on the line for typical towing applications, but could be swayed up to the bigger truck and a bigger trailer in the future

I love the chemistry Mr Truck and Andrew have.

It's difficult to get an accurate comparison in fuel economy running unloaded on such a short test loop. The Ram used 2.00 gallons, and the Chevy used 1.95 gallons. That difference could have easily gone the other way due to simple factors involved in topping up the tank. A longer mpg loop should be used.

Hahahaha! I love how Mr Truck says "Holy Cow Diesel is at $2.989 / gal. Here in Canada Diesel is $1.09.9 / litre which works out to $ 4.989/ Gal. Enjoy!

Finally! Been waiting for this!

Funny thing is that there is a RU-vid guy with his own page that said a 1/2 ton couldn't tow his 7,500Lbs. trailer Safely... So he Bought a F250 W/ 6.7 Diesel, Lol.

I've gotten over 800 miles on my 26 gallon tank. 33 gallon would be unreal. Love the Ecodiesel.

Hey guys! Here I am camping with my travel trailer, at just over 6,000 lbs. with my 2019. Colorado Crew Cab, 4x4, V6, my average mpg at the pumps today at sea level more or less, but hills on the Florida Turnpike, came to 11 mpg! At 70 mph!

Curious to see how both of these platforms last with their emissions systems.

You best do you research on the Duramax diesel it has a belt-driven oil pump that has to be changed every hundred and twenty thousand miles and you got to pull the transmission to change it 😠😠

Biggest and most important difference: Duramax engine is not a FIAT. That's a good thing.

I just got done shopping for a 1500 diesel. Ford was out because they dont offer in every trim. Chevy was a contenter until I found out the timing belts facing the fire wall are the Achilles heel of it. Ram interior feels spacious, has a flat back (good for dogs, and is really torquey. I am now the proud owner of a 2020 ecodiesel bighorn sport in white!

Way to go Chevy! Everyone was doubting the Chevy 0-60 & fuel economy!

Both good mpg for 1/2 ton trucks

Andre knowing diesel fuel prices better than Mr. Truck made me gain even more trust in Andre. He seems to be doing a lot of videos and really hanging in there with the channel. He’s been the guy I relate with the best for years.

“I inserted the noosle” 😂

This was a great example of true knowledge for people to know what a truck can do awesome job

Those a really impressive mpg numbers from both. It's good that ram offers the diesel in more trims levels, because the 8k price difference could pay for a decade of fuel

Glad you’re beating the EPA, it used 2 be I could never beat them ....I always thought they tested down hill or something. Lol

How many of us now fuel up, wait 30sec and then fill it lol 😂🙌

Im waiting to go to my basic training base and you guys don’t have the idea how happy I am to see this video, I was thinking I was not going to know the outcome of both of this truck mpg for a good time. Know im ready to buy my new 1/2 diesel truck once I get back to my hometown

Trucks are soo good these days... great results guys. Great comparison video as always.

Thanks to all you guys for your opinions and all your knowledge about trucks. Tks so much. Tk care to all.

Great comparisons. I would like to see a different truck from ram other than pre production. Also I'm not sure if it is 66 miles each way or total but I think the 98 mile loop will bring more accurate results

Amazing the difference in diesel price and truck prices watching this in December 2022

ive been waiting for this video for 2 years!!!

Great review as always! Now that fuel cost has doubled, these reviews are helpful to make informed purchasing decisions.

18 ram eco. Love it! SEMA 57 rat g asser! Love the video!,

That was a high price then, would love to see it now.

Great! Awesome to see these types of videos, now the Ike!!

Hey guys I just watched another video regarding the type of diesel you need to use for your trucks and it has to be top tier. And if you can't use top-tier diesel then they recommend using a diesel treatment every fill up

Max towing capacity is a big factor for those that will use a truck for towing, even if on occasion! Personally Ram with the higher towing capacity & larger fuel tank win.

This made my whole week....just picked up the 2020 Silverado High Country with the 6.2 L and the Performance Package (435 HP)....yep, scary fast...and yet, in the last two days, I have the fuel economy over 21 MPG by laying of the throttle a bit (Did I day that was in the hills of West Virginia....)

My Ram 2500 crew cab 4X4 gets over 25mpg highway unloaded at 65mph running a stock 5.9 high output common rail 325hp Cummins.

FYI: The 3.0 Duramax has a belt driven oil pump. Must be replaced after 150,000 mi.. Transmission must be removed to replace.

Great job guys 👍. Those are some impressive numbers for the highway gas mileage in a pickup truck. It’s most surprising that the Ram costs $41k. That’s not a bad price at all for a new truck. That was refreshing to hear after seeing all these new trucks that cost $70-80+k. Very nice comparison 👍

Can’t wait to see how these engines hold up over time.

🤣🤣 Mr Truck “you don’t know the song do ya?”

Note: I have a 2019 model ram and there is a recall note for the mirrors if you have the power folding mirrors. The internal gear strips out and will need replaced. If you plan on buying one with power mirrors test them out. Mine stopped working after 6 months.

Love your show, very informative, keep up the the great work guys👍🏼

To bad the Ram didn’t get the same mileage empty as it did last time. That would have been mind blowing.

I like this vid. I have to admit that I am a would-be Chevy/GMC person if I were to be partial to one make over the others. But it seems to me that the Ram, many times, has been a no-brainer with these modern trucks at things like this. And the Silverado is the ultimate underdog that I am so glad to see make a come-back at something. And if I'm correct, the 3.0L diesel Silverado still has under 300ft/lbs torque while the Ram is up to 480 but has been out for a while and been re-designed.

I gotta admit I love my '14 ecodiesel grand cherokee with the gde tune, but I've never ever ever been a fan of v6 engines. To me they feel like they have the torque of a 4cyl down low with the fuel efficiency of a much larger engine. Basically, I just don't enjoy the way they deliver their power. I've always loved a straight 6 configuration. To me they've always delivered nearly instant torque down low and given fantastic fuel economy compared to v8 counterparts. That's why I've always preferred Toyota supra's to corvettes and i6 jeeps compared to v8 off road monsters. I've never owned an i6 Cummins, but it's definitely on my "must own" list. I purchased my ecodiesel jeep instead of a Cummins 2.5 years ago because I'm averaging 30k+ miles per year. I tow between 1200lbs to 6800lbs every other weekend, but a little ecodiesel was more economical for my purposes driving 600mi/week unloaded. Of the 30k+ miles per year that I drive, at most I'm only towing 3k-5k miles of that, and like I said, the trailers are only 1200lbs to 6800lbs depending on the project that week. I'm extremely interested in the chevy 3.0l diesel simply because it's an i6, so the torque down low compared to the v6 ecodiesel should be immense. I don't really give a rats ass about peak torque, I mean sure it's great having a lot of torque, but really what matters is area under the curve. I want to know how these two deliver their power on a dyno, on the same day, same conditions, same time. The numbers that matter are how much torque each engine puts down off idle up to around 3.5k-4.5k rpm. The area under the curve matters so much more than peak, it really irritates me when people just "parrot" the claimed peak power number. Imo that i6 3.0l diesel could be something truly special. Let's get all 3 3.0l diesels and have a dyno day and overlay all 3 dyno graphs to compare the numbers at various points of the rpm range where the engines are usually being run day-to-day. Please TFL make it happen! ♥

WRT to the Chevy...Based on the gas vs diesel prices in my neighborhood of $1.97 for regular unleaded and $2.45 for diesel...Even at the rated 33 mpg highway you are only saving $2940 in fuel costs over the 5.3 over 150,000 miles at it's rated 21 mpg highway. I bet the mileage delta between the diesel and the gas V8 is less in city driving as well. Then there is the DEF fluid costs. The cost differential on the build and price tool for the 2020 truck on the LT trim is $5310 for extra for the 3.0 over the 5.3 and $6705 more versus the 2.7 I4 turbo gas engine. You have to really want a diesel to get this, because for the average suburban commuter you're not going to save any money on fuel unless you drive it 270,091 miles or more.

Great comparison! Thanks. How about a segment on diesel additives and maybe some mileage comparisons with and without. Love the channels!

Great work guys, thank you for doing this video it’s the type of information that’ll sway my decision when time comes to pull the trigger on my 1st ever diesel truck

man those are impressive unladen highway numbers.

Interesting. I have a 2020 silverado rst four wheel drive duramax. It also has a levelling pack so it is not elevated at the rear. I found the mileage to be similar to this demo pulling a 5000 lb (approx) camper in hilly terrain. Very happy with it so far. Purchased used with 50,000 km on it. )

I'd like to see a hyper mile test... take a 2wd truck, add a tonneau cover and a 2/4 drop. See how big a difference it makes, if any.

I have had 3.0 Liter diesels since 2006. They ALWAYS get better highway mileage than EPA numbers if you drive steadily.

Percentage wise the 3.0L diesels are taking a bigger hit when the trailer gets hooked up compared to gas. The Ram for the sake of easier math only gets 1/3 the economy.

I got nostalgia about times pre COVID watching this video

I’d be really curious to see a long term longevity test (100k+ miles of mixed city, Highway, loaded and unloaded use) to see how they stack up in terms of reliability. Both trucks I think would make a great truck, I just have a hard time trusting either one. The eco diesels suffered from cam gear slippage and emissions issues, and reading up on the duramax specs and how it’s made I’m not so sure I like all the aluminum used in the construction considering the higher heat diesels put out, even with iron cylinder liners. Also not so sure I like the fact that there’s up to 10 injection events per combustion cycle. Sounds ridiculously over complicated and prone to failure.

I must admit, I was not expecting that result! Good job to both of you, and good job, Chevy and Ram!

there are some other sites that do the mpg test and they have adapted your style of filling topping off the tanks guess you set the standards

Incredible! About to purchase the new 2022 updated model chevy high country

Great job, now please test what 80 percent of the market buys, A 4x4!!!!!

Thanks for taking the time to do these real world test. They real help us make your decisions.

the MPG drops similar (but worse) as a gasser. more load = more fuel...

I dont tow much or use truck for work only to carry my atv and haul a golf cart...but at this price and mpg is a no brainer one of these two is the best option even if you don't tow

Test the 4x4 Top of the Line versions of these trucks please!

Basically, if MR TRUCK isn't talking about it, I don't want to hear about it.

I have a ram 1500 5.7 but if I’m buying another Truck I’ll get chevy 2500 high country Duramax with a Allison Trans perfect combination( never mind I did some research and a lot of GM trucks and SUV have vibration and shake issues so no thank you )

"Diesel is almost $3!" That didnt age well....

All I know is my buddy got the Ram with the little diesel and has had nothing but problems with it. The dealer doesn't apparently know how to work on it either.

Good video. Thanks for the comparison. Results at 20:18

I prefer the styling of the Ram.

My wife’s ‘15 Ecodiesel Grand Cherokee has been flawless. I do like the inline layout of the Duramax though.

If only you had the power stroke too so you can do all 3

Much respect from everyone here at Vikingbags!

Nice job! But sadly- not so much on the singing....Curious- do you know what was the weight difference between the trucks?

Really like this comparison as I am looking at both of these trucks right now and weighing the options, but I got to tell ya, with a 7000lb load behind these trucks, an da 7000lbs load behind my 2016 RAM SLT 4x4 I am getting just almost as good mileage as the chevy, I am averaging 11.5MPG with 7000lbs and my truck is a 4x4. The only advantage for me would be the non towing fuel economy, best unloaded MPG for me is 24MPG. Great job fellas keep it up!

Why does the RAM temp gauge look like it is pegged in the Red?

This makes me feel kind of crappy about the Canyon/Colorado diesel. They still use the 6 speed auto where the larger engined and more powerful larger trucks achieve better fuel economy because of improved technology and the addition of the 10 speed in the case of the chevy. Would have been nice to see a mid cycle refresh for the diesel mid size trucks with the addition of the 10 speed auto added to it, along with revisions tcm programming to utilize it's torque/power curve appropriately. Shame these are so dang expensive. Would be cool to get one.

Great job guys! I’m curious how often regen cycles effect these tests. The passive regen modes are so difficult to detect in these trucks, but could easily swing the mileage dramatically one way or the other.

Great to see these comparisons but just like anything it's a different story when you start dealing with mountains all day, I live in western Canada and I never get even close to EPA ratings.

Super 1/2 ton diesel Ike gauntlet

Good video guys. Mr. Truck, those little mirrors are convex, not concave.

check out mr truck bouncing in the dodge at the 14.3 min mark

Thanks Fellas! What a great comparison! Thanks for what you do .

Did the Ram have a higher capacity fuel tank? If so then this might be the reason for a little less gas millage then the Chevy. But regardless really good stuff ya'll are putting out. The Ram is putting out HP and torque of what my 03 5.9 is listed as.

I LOVE THESE COMPARISONS!!

That's a really good result from both manufacturers. Amazing to see how these small block high torque motors have advanced.Anyone recall what the Fords results were? Great work Andre and Mr Truck.

I don’t know if it’s because the Ram is a work truck or if something is wrong with it. I’ve never experienced the leaf trucks riding better than the coil truck nor is that something else many other people are saying.

Too bad the Chevy has a tiny fuel tank

Very well done - great job guys. Appreciate the presentation and the info. Thumbs up.

So the Silverado & Ram diesels gets Corolla like MPG's. Expect truck sales to go through the roof.

wish they would put these engines in a 8 passenger SUV, wife drives 110 miles a day and suv MPG is killing us

Over 30 MPG is decent 👍🏻
