How Hard Do You Run Your 6.2L?

[AlaskaGriz]

So I am a motorsport enthusiast. I love the feel of the power/torque in my ZR2. I own a Jeep Wrangler 392 that is faster than this truck so I can get plenty of smiles/gallon with it too plus have 1000cc motorcycle as well.

Anyway, I am rolling up on 1000 miles on my newly replaced 6.2L. I haven't pushed it toooooooo hard during break-in but am somewhat gun-shy given that I had to go through an engine replacement already. I don't race around all the time but I certainly don't let regular passenger cars out power me either.

Do you owners run them up through the RPM range often? Want to get over my uneasy feeling about this 6.2L Engine toughness.

Thanks in advance for your thoughts.

Unleash it. It’s going to live or die so just end the suspense.

It's got a rev limiter at 6k. You can run it through the gears just fine between 3000 and 6000 rpm. Also use tow haul mode for a little more juice.
This truck is very sporty.

I can guarantee it runs and handles better than that Wrangler by a good stretch.

Only thing you can do to track engine wear is pull an oil analysis. Do one now and every 5k after and see what it looks like. You'll know if your getting excessive wear.

Most of the lifter problems are caused by when it's dropped the oil pressure and lifters out of the 8 cylinder mode. so babying it is when you're not in v8 mode.

Run it. if it's going to fail it's going to no matter what.

Based on the threads we’re seeing now, seems like lifters are less likely and now it’s bearings getting smoked or some other catastrophic failure….they’ll fail or not regardless of driving style or active fuel management being on or off. As you already found out, you’ve got warranty for a reason.

Grip it and rip it

I drive like my body allows me to move...

Change the oil and let her rip. I just rolled over 1200 miles and started giving it hell all the way to 98mph, lol.

i figured the same until i looked up the 392. 490 hp in the jeep vs. 420 hp in the ZR2 and the jeep is a few hundred lbs lighter.

that many hp in a wrangler is nutz.

I beat Supras, Vettes, and Porsche's all the time......mine goes 98 mph!

I drove mine like I stole it for just over 50,000 miles prior to trading it in. No problems. I got on it constantly, as I do everything I drive. It’s a 6.2, get after it!!! Good times

Thank you all for your feedback. Looking forward to playing harder with this truck.

Here's a picture of it.

Nice, dude! Good to see another Alaskan ZR2!

I’ve been driving like a shithead since I passed 1600 kilometers (1000 in freedom units). Who knows, it might grenade someday, but I’d rather live with my nuts out than pamper it. I got the loud exhaust for a reason

 

[TKO-ZR2]

Babied mine for the most part for the first 5600 miles prior to engine blowing. Not anymore, I'll be lucky to average 10 mpg moving forward.

1st Oil Change is next Thursday. Will be about 800 miles on new engine. Then I'm not babying it anymore. Bought the GM Platinum Extended Warranty yesterday.
