What should the RPM be at 70 mph?
I'm curious, could you please elaborate on what the recommended RPM range should be when driving at a speed of 70 miles per hour? It's important for me to understand the optimal engine performance and efficiency in relation to speed. Could you possibly provide some insight into the factors that might influence this RPM range, such as the make and model of the vehicle, the engine size, and any other relevant factors? Thank you for your assistance in clarifying this matter.
