At what RPM does a car give the best mileage?
Excuse me, could you please elaborate on the relationship between a car's RPM and its fuel efficiency? Specifically, I'm curious to know at what RPM range does a car typically achieve the best mileage? Is there a specific RPM threshold that most vehicles tend to perform optimally in terms of fuel consumption? Additionally, are there any other factors that can significantly impact a car's mileage beyond its RPM, such as the vehicle's weight, engine size, or the type of driving conditions it's subjected to?
At what speed does a car give the best mileage?
Can you elaborate on the factors that contribute to a car's optimal mileage and how speed specifically impacts it? Is there a general rule of thumb or does it vary based on the make and model of the vehicle? Additionally, how does one determine the most efficient speed for their particular car, and what are the potential benefits of driving at this speed?
