Honda tells you to leave it in.
The mods on the Honda Ridgeline forum claim to have discussed with factory reps and claim there is no special break in oil - HOWEVER the break in oil is moly rich from the assembly lube used and they want it in until the MM indicated 20%. My dealer said the same.
Next conundrum is the A/B filter change - Honda only wants you to change the filter revery OTHER oil change.
