I have a 2025 ZR2 3.0 diesel and love it. Had the 6.2L before and don't miss it. The diesel is quick off the line, fuel efficient, powerful and quiet. The only thing I miss about the 6.2L is the sound of the exhaust. That's about it.
I average about 22mpg with mixed driving. I haven't made any big road trips yet but some are saying 26mpg and above. I'm actually surprised you're getting almost 19mpg with the 6.2L. Are you using the stock Goodyear 32" tires?
Have you considered the new LZ0 3.0 diesel? I went from a 2024 Silverado HC with 6.2L gasser and traded it in b/c of recall and went with the 3.0 diesel and have no regrets. This motor is snappy with nice acceleration off the line, quiet at hwy speeds and so much more fuel efficient than the...
Isn't the 3.0 Duramax terrific? I sold my 2024 Silverado with the 6.2L and went with the 3.0 Duramax too and so far loving it. Snappy acceleration, quiet, fuel efficient. I love this motor! Don't miss 6.2L (other than that exhaust note when in Sport mode lol).

I was hoping for more! What results are you getting? Also, any truth...
Anyone use this mode? I've tried it but with the diesel it doesn't do too much I don't think. Maybe shifts a bit quicker and a bit firmer suspension but not that noticeable.
I'm coming from a 6.2L High Country where it changed the exhaust to basically a catback and definitely made it handle...
Hey guys,
Just took ownership of my new ZR2!
I have an interesting back story on this. Back in late 2023 I wanted a ZR2 so I took it out for a test drive and the best MPG I could get on the HWY was 17! No good for me. So I bought a 2024 Silverado HC with the 6.2L motor. Love that truck...
