Re: Oops...didn't break-in engine

Here's what the manual says.

ENGINE BREAK-IN RECOMMENDATIONS
• A long break-in period is not required for the engine and drivetrain (transmission
and axle) in your vehicle.
• Drive moderately during the first 300 miles (500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.
• While cruising, brief full-throttle acceleration within the limits of local traffic laws
contributes to a good break-in. Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
• The engine oil installed in the engine at the factory is a high-quality energy
conserving type lubricant. Oil changes should be consistent with anticipated climate
conditions under which vehicle operations will occur. For the recommended viscosity
and quality grades, refer to “Maintaining Your Vehicle”.
NOTE:
A new engine may consume some oil during its first few thousand miles (kilometers)
of operation. This should be considered a normal part of the break-in and not
interpreted as an indication to an engine problem or malfunction.

You haven't strayed much.

Re: Oops...didn't break-in engine

(Snorkle) If you go WOT at almost any legal speed you will be in a lower gear. Also back in the bad old daze when an "economy" gear was a 3.08 and top was 1:1, most engines would be turning over 3k rpm at 70 so speeds under 60 for the first 500 miles were advised. Today you are turning 2K or less at 70 and bearing materials, tolerances, and oils are much better so fagedaboudit.

Any late precautions I should take?

Thanks
Unless you were on the Utah Salt Flats, even with cruise control on your engine speed varies.

You are fine.

Your motor was broken in when you drove off the lot.

But seriously, folks, the old fashioned way of breaking in a vehicle has gone by the wayside (thank goodness!). I would not recommend doing misdemeanor/felony level speeds until at least a thousand miles are on any vehicle, but driving at varied highway speeds for a couple of hundred miles is about as much that may be required or suggested. Some folks drive more carefully the first ~50 miles to properly "scuff in" the tires... not a big deal unless those miles are in heavy rain.

Our first trip in my wife's new GC was from central NY to Fairfax, VA and back... that trip went great, and helped convince me to get one. The first trip in mine was to West Orange, NJ (to celebrate) and back.

About the 1500-mile guy, did he buy from Dave Smith? His account of the deal and the trip home (i.e., how he likes the Jeep) would be most welcome here.

Re: Oops...didn't break-in engine

Break-in like the manual say.
NOT for the car but for the OWNER/DRIVER.
Since need bit time to be all-in-one with the new car, also to have time to feel if there is something strange (sound, brake, gear, feeling etc etc) and so will talk with garage without damage.
My 2 cents.
