The light-duty Chevy Silverado 1500 is offered with a variety of different powertrain options, including several different gasoline engines and even a diesel. Now, GM Authority has identified two Silverado engines that are equally popular among buyers – the naturally aspirated 6.2L V8 L87 gasoline engine, and the 3.0L I6 LZ0 turbodiesel Duramax, both of which are spending roughly the same amount of time on dealer lots before they are sold.
Interestingly, units of the Chevy Silverado 1500 equipped with the 3.0L I6 LZ0 turbodiesel Duramax engine are turning in 42 days, on average. Meanwhile, units of the Chevy Silverado 1500 equipped with the naturally aspirated 6.2L V8 L87 gasoline engine are turning in 40 days on dealer lots. That means buyers are equally as attracted to the optional diesel engine as they are the range-topping gasoline-powered V8.
Notably, General Motors is now the only OEM that still offers a diesel engine option in its light-duty pickup models. The 3.0L I6 LZ0 turbodiesel Duramax was added to the Chevy Silverado 1500 lineup in conjunction with the 2023 model year, replacing the 3.0L I6 LM2 turbodiesel Duramax offered prior to the launch of the 2023 model year. Output form the LZ0 is significantly improved compared to the preceding LM2, with the LZ0 rated at 305 horsepower at 3,750 rpm and 495 pound-feet of torque at 2,750, as compared to output of 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm from the LM2.
Meanwhile, the naturally aspirated 6.2L V8 L87 gasoline engine has been on offer for the Chevy Silverado 1500 since the 2019 model year, launching as part of the light-duty pickup’s all-new fourth generation. Output is rated at 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm.
Further engine options include the TurboMax turbocharged 2.7L I4 L3B gasoline engine, rated at 310 horsepower at 5,600 rpm and 430 pound-feet of torque at 3,000 rpm, as well as the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower at 5,600 rpm and 383 pound-feet of torque at 4,100 rpm.
As a reminder, the Chevy Silverado rides on the GM T1 platform, while vehicle production takes place at the GM Fort Wayne plant in Indiana, the GM Silao plant in Mexico, and the GM Oshawa plant in Canada.

Night and day difference between my 6.2 and 5.3 engine. My 6.2 engine rocks!
That is great to hear. Please break it in well, and check your oil for glitter after 500 miles, and if there is, GET RID OF THEM ASAP. Afterwards, change at 1k and then every 3k-4k using the right oil type and filter…and driving style matters as well.
There has been some small number of bearing issues with the 6.2, where the engine tends to throw a rod. Mostly in MY22s and MY23s (CSP exists for that), and some MY24s are affected as well. As for the MY24s, I am not sure if it is early-middle builds or late ones, since I heard there was a part change at some point- hopefully MY25s will not have this issue, or it will be fixed by the generation end.
That said, while the issue is concerning, they sell 800k+ trucks per year, so between 10k and 30k could fail due to any reason (bearing issues included)…. So the rate is around 5-8 percent…but still do not worry- as long as you do not baby it and drive it properly, you likely will NEVER face a problem.
Night and day really? The 6.2 is less than a second quicker in the 1/4 and only 5 mph at the traps, that is FAR from night and day. 5.3 is the best choice as you don’t need premium to get the full numbers and it isn’t far behind the 6.2 while getting better mpg. We have both (5.3 in Silverado and 6.2 in Denali), there isn’t much difference.
I use my truck as a truck. Don’t care about 0-60 times and a 1/4 mile time. Somewhat regularly pull 4,000 lbs and 8,000 lbs. When I move our skid steer, I’m pulling 14,000lbs plus. 5.3 works too hard. Don’t want a 2500HD diesel because they sit too high, 12 grand more and won’t pay more for diesel fuel than gas because I remember when diesel fuel cost less than gas. And, 30 years of sports car racing, I can tell a difference in a second on my way to 60 mph even though that’s not important to me for any street vehicle.
I love my 3.0 diesel. Tons of torque and the mileage is incredible. This country should embrace diesel and not shun it. The whole vw thing was a vw thing. They are cleaner and reliable and you don’t have to did huge holes in the earth to get to the minerals to make them. Wake up america.
Too many horror stories in the Facebook groups. I’ve seen literally hundreds of posts. I went with the 2.7 because I see the least posts about major failures. Of them you get the crappy 8 speed. Can’t win these days.
will GM put a 6.2 in a 2-wheel drive 2025 1500 truck?
GM seems to have eliminated that combo a little after covid stuff.
Haven’t seen that come back, unless it’s the 6.6L gasser.
Give me a 2.7 with an Allison transmissio!
I purchased a brand new 2023 Chevrolet 1500 high country 6.2L in September of 2023. Changed oil every 5000 miles. I was going on vacation to florida with in on November 16. I got 120 away from home and the engine blown up. The dealer gave me a rental car. I asked for a truck and received a chevy trail blazer. It had none of the features of my truck. The window sticker was $29,000, compared to my truck of $76,000. They do not have a replacement motor and don’t know when one will be available. I will trade as soon as i can. DON’T BY CHEVROLET SILVERADO WITH ANY MOTOR.
If that rental car is what they have, then I am afraid you have to be with it. Or, if you have the cash, you can rent a truck elsewhere. Yelling at the dealer or the manufacturer WILL NOT SOLVE ANYTHING, since the 6.2 engine is likely on backorder – supplier issue, so it is out of their control.
I am waiting for the end of this generation to really see whether this fiasco ends…
Jon, do you have any up dates on your 2023 6.2 truck?
I have the 2023 RST 6.2 with just turned 3,000 miles,
.I bought it with 2,000 miles.
I have some questions about a engine noise that could just be the oil pump,
maybe really an bearing noise Its noticeable to an engine guy,
Take it to the DEALER ASAP, if the noise is loud knocking.
If so, the engine is likely defective and falls underneath the CSP of MY23s.
Last thing you want is to be stranded in a haunted highway….
BE PREPARED for no loaners, and long wait times. If you have a secondary car, use that or try Hertz or etc if you have the money too…
Since the transmission self-destructed in my 2019 Silverado LT at 52,000 miles, I think I’m done with GM.
None of the other brands are any better, including Toyota.
2017 LTZ 6.2 liter very well maintained and always ran 93 octane gas. Engine blew up at 98,000 miles. Was quoted $16K by dealer to replace engine. The eight speed tranny was bound to fail shortly after. The 6.2 was a fun truck but will not repeat. The 5.3 is the way to go.
I guess you got a lemon. I know others are at 250k-300k+ with no issues…probably a lot. But lemons unfortunately exist.
16k is not cheap- you can get better quotes, but it is better than the 20-25k+ for Toyota truck engines…
I’m satisfied with my 2007 GMC Yukon XL with 268,000 miles on both engine and trans and I pull a 7,00 lb tv trailer.
That is great to hear. Change your oil every 3k to 5k miles using right type+ filter, and you can get 900k+ out of it- no joke.
I’ve got a 2025 RST with the LZ0 and it’s awesome. Regularly get 30+ mpg at 70mph. It’s quiet, smooth, and plenty fast. I use it to cruise to a remote work site every week. Absolutely love it.
