And if you want to get real technical, the 2020 3.0 engines had a better EPA rated mpg. See that comparison below.

I wouldn't say $15K since the Equinox is a Premier, but you can easily say $10K. You can or can't see the difference in mileage, but since I am the one who fills both vehicles up (wife hates to get gas), I know what both get for mpg. 

 

Believe what you want on the 2-vehicle comparison (RST 3.0 vs Equinox 2.0T) of vehicles I own, but even the EPA's site shows the Equinox cost more to drive. You can see the personalized info as for driving I used on the bottom. I also used fuel cost in my hometown (regular - $3.09, Premium - $3.69, Diesel - $3.08). I'm getting more than TWICE the amount of miles per tank than the Equinox gets. I average right at 700 miles per tank in my 3.0. I don't wait that long to fill up though. Per the EPA info below, you will have to stop in 200 miles earlier in the 5.3 than the 3.0 and the cost to fill the tank will be the same.

 

After you look at the cost to buy each, the cost to drive each, and the resale/trade-in value. I'd still go with my 3.0 over either of the three. The 3.0 is only a $1k option over the 5.3 in the 2021 model year in a RST; in the LTZ it is only a $750 option.

I’ll say this. I was intrigued by the SUV must be a blast to drive. Probably why you all get under the EPA fuel mileage. I've owned all kinds of diesels for different reasons. Even modified a few. All before the latest EPA requirements. With the offerings these days I’ll never own another. Especially for fuel mileage.

I love my 5.3L in my 2019 RST... especially with the GM Performance Exhaust and Cold Air Intake. But my next truck will have a 3.0L diesel in it. You just cannot beat that MPG. And gas prices are going nowhere but UP in the days ahead. 

And so is Diesel prices, diesel here is 40 cents more per gallon over 87 and I don't know where this guy is from but he needs to check it. The extra cost per fill up is about a wash when it comes to better mpg in the diesel then the 5.3.

 

I have been through the Diesel motor days with my Duramax 6.6 LLY pulling boats but I will never go back to a Diesel motor these days with the extra fuel cost, maintenance, and mostly all the emissions that are on these motors now.

22 MPG average and 100K powertrain warranty I'm sold on that. yea I was considering the 5.3 not anymore ! 

thank you for the response 

Yes the 3.0 and the 6.6 duramax engines both get a 100,000 mile powertrain warranty but it's still only for 5 years. So if you plan on putting 100k miles on it in 5 years it may be worth it.

Of course diesel will also go up. But when you're averaging 8-10mpg better in the 3.0L, your cost does not go up as quickly owning the diesel.

I have the 3.0 .... and will never do gas again.

Please elaborate.....Issues or something else?

I had 2 prior trucks with the 6.2L  ...  it wanted premium fuel and drank it like a sailor.  Couldn't take it anymore.

 

My 6.2 never saw better than 19mpg with 17 average using premium in real driving.

 

My 3.0 has done 30mpg with 26mpg the real 75mph mileage.  So average about  30% more per tank.  Here diesel price is about the same as midgrade fuel.

 

The only pain is DEF which is pennies added and a fuel filter at about 18,000 miles for $12.00  Still blows away the gas engine.

 

Emissions problems? Who cares? it's under warranty.  I've been back one time for an updated ECU program related to emissions.  I wont mention leaking rear window though.

And DEF is easy when you have access to a truck stop to fill it up while your filling diesel.

 

Out of curiosity, why did you change your fuel filter at 18,000 miles? I changed mine at 22k because it was down to 30% on the life monitor.

 

The leaking rear window is hit or miss on all of these trucks, not just the diesel. Knock on wood, but I'm lucky to not have had a leaking rear window nor the crank no start issue.

Sounds like the OP's mind is made up, but just adding a data point for those interested in this in the future. My 2020 5.3L averages around 20MPG on the highways and 17 in the city. This is with auto start/stop manually disabled (every frickin time I start my truck) and a CAI cold air intake. Everything else stock. I have a slight lead foot. I'll be pulling a 22' center console boat (roughly 4K lbs) soon and I'll report in the gas mileage towing that to the beach and back (2-2.5 hours).

 

edit: the 20MPG is what I see normally (day to day doing about 45 miles and mix of city/highway). My best 400 mile MPG was 21.9 which was done on a trip from Orlando, FL to Durham, NC.

 

Also, I'd never consider diesel due to additional cost from DEF and the fuel itself. Maintenance, other than oil changes, I have done via the dealer or a local shop I know who has serviced other vehicles of mine. Diesel has always a more expensive option for shops to do maintenance on.

 

In the end, gas 5.3 was the best option for me and pairing that with the 10spd auto makes it a no-brainer in my book for those who don't want to deal with the hassle of diesel or premium in a 6.2.

I admit I'm a diesel fan. (many years running 6.6's)

 

If you are ordering an AT4 (and although I haven't been looking, it sounds like there aren't any on the lots) you'll have to choose between the now standard 3.0 or the slightly more expensive 6.2.

 

The 5.3 is no longer an available on the '22 Limited AT4. (and the 2.7 isn't available on an AT4 either)

The AFM 5.3/6 speed has been discontinued, and the DFM 5.3 with 8 speed is being used on the trims that previously used the AFM technology.  Presumably making the 5.3 unavailable on AT4 helps balance production volumes.

Maybe all this changes again when the mid-cycle enhance '22 arrives.

 

'Here', diesel is running about 10% less than regular 87 octane.

Premium for the 6.2 is about 25% more than diesel!

C$/L -- but the ratio will be the same

Diesel - 1.22

Regular 1.36

Premium 1.52

 

Mine is mostly daily driver with a little towing. 

Speed matters. Starts and stops matter.

Most driving has been 55 - 60 mph 2 lane,

First 8700 miles have averaged 26.5 usmpg. 

I ran a 4wd DC '15 6.2/8speed and a 4wd Crew std box '16 5.3/8speed.  Both got about 19 - 20 usmpg doing the same task.  

 

Towing at freeway speed 3.0 it only gets low-mid teens, but tow miles are included in the average. 

The 5.3 / 8 speed towing the same enclosed utility trailer on the interstate from Port Huron to Phoenix and return averaged about 9.5.

 

DEF cost hasn't been a factor, especially compared to the rest of the costs of owning/operating a pickup.

Topped it up at about 700 miles, and 8000 miles later squeezed in 5.5 US gal (yes, a little over rated capacity)

1438 usmpg.  Cost was C$18.78 or about US$15

The 5.3 V8 was discounted by $10,000 so it was a no-brainer for me. Now the dealers are no longer discounting them, it's making my decision a bit harder. I get around 25 mpg on my 5.3 V8 (best I've gotten was 28 but that was going 50-55 mph all the way on a flat surface).

 

If I can get a Duramax for less than $2,000 more, I'd consider it, because that's how much I'd save in gas mileage after 60,000 miles. Right now, I get $6,000 off for gasoline and nothing off for diesel so I'll stick with gasoline for now.

I was down to around 10% and oil change was due ... Just did it all at the same time.

FWIW, my trucks life is 95% towing.  I'd imaging that has a lot to do with it.

To add a real life experience.  I do a regular weekend trip towing an enclosed trailer roughly 240 round trip.

On my prior 6.2, I'd have to fill up with about 50 miles remaining on the last leg.

With the 3.0, I make it there and back and have, on average, 1/4 of a tank left.

Again, that's real world comparison.  And in my opinion, enough to settle any debate for me.

WHAT??!!  Everyone else with a 6.2 seems to be getting 50 mpg and doing sub 10 second quarter mile sprints all while pulling a 45,000 lb trailer. LOL.  Finally some honesty!  Thanx Steve!

    • I had an issue with a new 1985 Z-28 some years ago. The 4WDB's were less than adequate when purchased IMO.  I had taken it in for small warranty services and asked them on three occasions to check them. Each time is was "could not duplicate on the service ticket. The warranty ran out about a month after my last visit and had to take it back for warranty rework. I again complained about the brakes. Well, low and behold, this time they determined the rear calipers were sticking and gave me a quote to repair. They had records as well as O had receipts of each time complained about the brakes while still under warranty. My dad was a life long body shop owner and told me to keep my cool and tell them that I wanted to speak to the GM Regional District Manager. The service manager disappeared for a few minutes, came back and told me they would replace the calipers free of charge. 
    • Towing a 2022 Lance 24 ft travel trailer with our 2021 GMC Sierra 2500HD, gas.  Loaded, trailer is about 6,000 lb.  We get up to 10 mpg at 55 mpg, such as I-5.  Pleased with the combination.
    • I decided to give it a shot and see what sort of a gong show it would be to a pan drop themed oil change on my 2025 gas truck with the 10 speed. All indications I had seen so far was that there was no way that pan was coming out of there due to the cross over exhaust pipe not allowing enough clearance for the back end of the pan to duck out from under the valve body since it hangs lower than the pan to trans mount flange and certainly the filter does. I never touched any of the exhaust mount hardware at all, be that the engine manifolds to Y pipe, the bracket on the side of the transmission, or the two bolt flange further back behind the trans/transfer case. I put the truck up on four jack stands as there was no way I was going to struggle with that lack of clearance under the truck. The truck was cold as it had sat over night so all the trans fluid had drained to the pan, so I drained the bit of oil that would come out of the level check plug at the bottom near the front of the pan and put the plug back in to reduce the ensuing mess after that. Then took out all but one bolt front and rear and then pushed up on the pan and took out the remaining two bolts and then let the front of the pan tilt and spill out most of its contents into a drain pan. I then popped the pan gasket off its two locating nubs and kicked it a bit to the left side so it was no longer on the flange of the pan to get all the clearance I could and managed to get the pan slipped out of there by swinging the front of the pan to the right but keeping the rear part of the pan inline if not slightly to the left of its mounting flange area and lifting the front of the pan enough to keep the rear part of the pan low enough that allowed the pan to "JUST" slip out without forcing anything. I installed a new trans filter and seal and as per GM instructions on this site I torqued the two bolts to that 44 inch pound goal ( they take an 8 mm socket ) In reversing the pan procedure after I had cleaned up the pan both inside and out completely ( touching the outside of a dirty pan and dealing with installing a gasket at the same time would be a disaster ). First I slipped the pan into place and yes it took me a while as it won't go unless its slid in just at the right angles, then once the back of the pan was into the area of the flange mount, I went and got the gasket and then threaded that through the front of the pan and feeding it under the filter etc and finally working it onto the flange of the pan and lining up the two locating nubs to drop into the pan. Then lifted the pan up into place and get a couple of bolts started and check and make sure the gasket is where its supposed to be as the bolts were being put in. I never used any power tools as I don't have any of the whimsy little drive guns, I use what looks like a small screw driver handle with shank that has a 1/4 drive on the end of it and added an extension and those bolts use a 10 mm socket as some times power tools can bite a person if used on delicate parts ( torqued to 80 inch pounds ). Also should note as per rules around pulling the add plug out first, yes I cracked that loose with a 8 mm Allen bit socket on a 3/8 slim head ratchet as there isn't a lot of room to work with there either due to the exhaust on the right side of the trans.    I already had delco ULV oil on hand and of course the quart bottle pump wasn't made for those small cap threads so I had to use some other containers that the pump would fit and keep transferring oil over into them so a wasted exercise there but indeed the small pump did work just fine as ULV oil is thin and easy to pump in summer time weather. I put in 9.5 quarts as per prior minimum recommendation and yes that cut it pretty close as once I had the truck ( off the jack stands so its level ) and the trans oil up to 167f , about 6 ounces came out but a level kit or what have you could throw it off just enough that it wouldn't be enough oil so probably that 10 quarts is a good amount to put in so one doesn't have to add more oil as when its hot I sure wouldn't want to be adding oil so would have to let the exhaust cool. All I do for warming up the transmission is sit there with it in park and rev it to about 2500 rpm and it takes close to 20 minutes to get it up to that lower limit of 167f, weird how it will warm up more doing that then by driving it, I am not real keen on power braking the truck to get the temp up there and don't seem to have to either. By the way I only have 9000 miles on the truck so probably not a very good payback on doing it that soon and the magnets had such a minor thin layer of fines on them so that was good to see and the color of the oil was a darker red then new oil but still looked very good as it should and I've not done any towing with it so its been living a pretty easy life so far. The filter is made in such a way that its next to impossible to pull out the filter media but there certainly was some fines showing up there which makes sense give the trans having to break in.    I hadn't really planned on explaining this much of what I had done since there are various instruction videos kicking around or I think so, as the gist of my message as that by fluke or what have you, for some reason my truck has just enough clearance to slip the pan out from the trans. Of course there is no guarantee that other trucks like this in general will also allow the pan to be taken out without messing with the exhaust as I expect its probably a crap shoot if it will or won't, I was just happy to find out that mine would work and avoid all the other struggling and possibly damaging things in the process,     
    • Do you fellas think Fog Lamps would  be a good upgrade for our 2024 2500 HD Custom ? As you probably know it did not come with them ,  Would you put in GM Chevy parts ? Do they get wired up to the switch panel ( Upfitter or whatever the correct terminology is ) on the dash ? Thanks
