What is your break-in routine for new vehicles?

[Battousai1]

This is just about right. just vary your speed and never exceed 120 kph or gun the engine past 60% of the red line (more or less 2700~3000 rpm for a diesel and 4000 rpm for a gasoline engine). so long drive, laro ka lang between 80 kph and 120 kph. do not idle for long periods.

Pa-bless mo sa manaoag tapos diretso akyat ng baguio or swimming sa hundred islands, break-in na yan pag uwi mo sa bahay.

Thanks for the reply. However, the question now is what if you weren't able to properly break-in the engine during the break-in period? Can you still get the full fuel economy potential of the engine if you break-in late even if vehicle mileage is already at 3,500 km. but still no proper break-in procedure done, worst, vehicle has been used in some heavy traffic conditions.
