In both my Maximas 09(94k miles) and 11(96k miles), transmission is programmed to run the most efficient (lowest RPM possible) for the speed, I seldom see my tachometer get to 2.5K RPM, with most of the time between 1.5k and 2K, unless driving uphill. Even at highway speeds of 70mph, RPM sits at like 2.1K. And to be honest I am nervous to give it more gas for higher torque since the CVT in these cars is the weakest point.
I was thinking, would that (at least on the long run) cause oil slugging, low flow and accumulation of carbon deposit? and would that concern for less than ideal lubrication and oil flow for the engine?
I use PUP5w30 (5w30 API SM or SN is user manual recommendation) and Nissan filters every 5k miles in both vehicles. Both are well maintained cars.
