If someday you need to rev higher you risk the possibility of breaking your rings or piston ring lands because when you hit the higher rpms the rings will bump into this ridge that is sticking out. That is why when someone "Finds" a great deal on a car that has been used by a little old lady and never driven hard and a young driver gets in and gives it the wack most of the time it's not long before the great deal falls apart.

You are not doing your engine any great favors by never revving it Honda's are designed with high rpms in mind and will last just as long if you take it to red line once a week or so. You do not mention how many km you have done already, if you still have low Km's or it is a second hand car start giving it some revs over a month or so like next week take it up to 4,000 a few times a day then the next month up to 5,000 for the next month and finally up to 6,000 or redline and kept hitting 6,000 or so once or twice a week for the rest of the time you own the car. If it's a new car start right now and take it up to 6,000 or red line but don't stay there for long and do this once a week and you will be fine and it will last longer than you will want to keep it.

Thanks for the reply. I bought the car brand new and its done about 59k. Is it too late? Also, its an auto, so how can I get it to reach the higher revs? At 120km/h its at 3000rpm (barely).
