What is your break-in routine for new vehicles?

[yebo]

run the engine to higher RPMs and be able to constantly change RPMs without interruption due to tight traffic.

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.
