Italian tune-up?
How should I drive it? My suburban is now licensed and on the road!
 But should I drive it like I do my Mercedes, where I look for opportunities to run high load at high RPM? I know that activity as an Italian Tune up.Since I'm new to driving a 6.2L, I want to do what good for the engine. My OM616 and OM617 engines are happiest if they get hot combustion chambers now and then to clean carbon out. Is the 6.2L the same? Or should I not bump the governor in 2nd climbing that big hill?

Congrats! I drive it between 1800 and 2500 rpm.
I can hit 40mph in 2nd gear Biodiesel will also clear out the carbon and sludge.

Thanks zetan. I was not so much wonder how to drive most of the time. Rather, is it good, bad, or indifferent to run high load at high RPM every now and then? I have very little experience with these middle-sized engines - I'm pretty comfortable with <3L and >12L.

If the engine is healthy, running it up to the governor won't hurt a thing. I am a big proponent of fuel additive to keep injectors clean and spraying a nice atomized mist of fuel.

With 4:10 gears , a sm465 and my need to go 70 my truck gets a tune up every time I drive it lol
I have heard it is also good for TDi's to keep a build up of oil out of the intercooler. A run through the gears at 4500 rpm

I run mine to the governor often.
4.56's dont leave much option. The engine handles it well.

We run ours up to high rpm frequently, helps keep marine injectors clean, and lots of time to just get the motor to warm up and heat to come out of the heater. Sometimes think we got too many cooling mods....LOL (only think like this in the winter...LOL)......never had a problem being too hot in the summer though. Gotta think on positive side...LOL.

Before my turbo motor I ran it up to the governor a lot! Never had an issue. Even had it up to the governor once on the highway with a TH400 and 4.10's it's easy :P
But I have no problem running em up though, they're motors that like to spin!
