I have a 2019 Nissan Versa Sedan equipped with the manual transmission. I’ve had it for a couple of months now. I just hit 1,000 miles on the car. I am wanting to know other owners point of views on when to shift up. I have a 1994 Honda Accord (also a manual) that i shift at 3k rpms. The Nissan Versa seems to have a smaller 5th gear which hits 3k going 60 mph. Will driving on the interstate for long periods of time reduce the car’s lifespan (since the speed limit is 70, and therefore i am over the 3k rounds per minute for long periods of time.)? My accord hits 3k at 70mph... just wanted to know everyone’s opinions on when to shift up and the long term effect of driving on the interstate going 70 in 5th gear at 3.5-4k rpms in the versa. I do have cruise control equipped on this 2019 versa s.
