In a car that new, it's not going to matter. If you can afford for the tank to get quite low every time before you fill up, and you intend to keep the car for a long time, you will avoid the sludge buildup and water accumulation in the tank that is the reason that many old timers will tell you not to let the tank get low.

There are two ways to break in a Honda motor. If you want the motor to last forever, like the typical Honda motor, do what the dealer said.

You can get a couple of horses out of the motor by beating it from the very beginning, but you will shorten the life expectancy of the motor by an unknown mileage. Most of us would think it's not worth it, and would do what the dealer says.

Although badly informed mechanics and even service supervisors will deny this, Honda/Acura does use a break in oil. This is verified by reliable information out of Torrance, and I don't care what your mechanic says to the contrary.

Because they are deliberately wearing the motor by using this oil and recommending specific driving techniques for a specific mileage, I would recommend you leave the break in oil in the car for the mileage specified in the manual. Leave it in at least 5,000 miles if you can't resist changing it early.

My only caveat is that you watch the oil consumption closely while the motor is new. K motors will often use quite a bit of oil while they're breaking in for the first few thousand miles, often for the first few oil changes.

My K20A3 was like that. It used oil at an alarming rate, almost outside the warranty specs, for the first couple of oil changes...the dealer even had to add oil while it was in the break in oil cycle.

However, now it uses no oil at all between its 5,000 mile changes.
