any one have any tips on breaking in the H-6 Boxer engine for optimum fuel economy and life of the engine.

 

mine is still to new

 

I believe the owners manual (can't say specifically, since I haven't seen the specific Tribeca manual yet) will tell you the recomended procedure.

From what I've heard, generally just baby it for the first 1000 miles. Don't take the car much over 3000 rpms. Also, don't cruise at the same rpm for long periods of time. If you are on the freeway, vary your speed up and down as well as rpm's. In breaking in my car, I would shift between 4th and 5th during the break in period.

Other then that, you don't really have to worry too much about break in. It is mostly unnecessary (though you do want to be cautious) because motors today are created with much higher precision then in years past.

Good luck with the vehicle, I hope you like it.
