How long did you wait to accelerate full throttle after new?

[gmissed]

10 heat cycles sounds reasonable. Manufactures of new cars I've had all recommend between 500 and 1500 of mellow driving to break it in. If it was better for the engine to hammer on it right away, they'd tell you to do that.

 

Had to ask. What's in the back?

Looks like a snake in a swimming pool net.

I think it's a puppy.

Just drive it whatever way makes you feel good. I'm pretty sure the motors get a bit of break in during their diagnostics and testing when they are built.

It looks like an alligator.

Thanks for the inputs. btw does anyone know the sweet spots on the 6.2? I read anywhere over 40mph.

Im pretty sure old guys like me remember the old 500 mile break ins and first oil change at that time. But these new engines are machined to closer tolerance and assembled cleaner inside than the old engines.

 

Still, driving moderately will make any engine and vehicle last longer. But it's only money. Drive how you feel like spending. There's a direct correlation between cost of operation and how you drive.

On the test drive with 13miles on it.

Never have.

6.2 Sweet spot... 106-128... (track only of course.)

motorcycles they suggest riding it hard and wide open. something about making the rings seal to the pistons and side walls faster and cleaner than a slowly broke in engine. i drove mine pretty hard the first 1k miles, no issues.

Chrysler manuals all recommend upper gear, full throttle bursts during the first 1000 miles. I was gentle on mine for maybe a few hundred miles but the whole under 55 for the first 1000 miles is impossible. I had it at 70+ on the ride home from the dealer. Doing 55 on the highway is unsafe.

I drove the truck like I would normally. The main thing for me is to vary RPMs and not let it sit in one spot too long. I've broken in every vehicle I've owned in this way and never had any trouble so no reason to change.
