At speed, the engine is working harder and as such generates more heat. If the cooling system is not functioning properly, the engine will run hotter. Recognize, however, that the engine may just be running very cool when you drive around town, and it just gets up to the thermostat set-point when it's working hard. If it's not overheating, you're probably ok. If you have any doubts, change the thermostat. But whatever you do, don't run the engine if you are loosing coolant. That particular problem has to be resolved quickly, before you cause serious damage to the engine.
Many times when calculating miles per gallon, automotive companies will list both city mpg and highway mpg. City driving includes less miles, but more stopping and starting, and idling in traffic.
The highway code changes every time a new law or amendment about driving is passed.
Cars are rated as to how efficient they are. The government gives them two ratings; Highway mileage and City mileage. City mileage is determined by driving the car at slower speeds and stopping and starting many times. This consumes a lot of fuel during the times the car is not moving or having to accelerate. Highway mileage is determined my driving the car long distances at highway speeds, usually 55 mph or more.
Stopping and starting. Needs more fuel to get mass of car moving rather than keeping it moving.
They "reset" while driving at highway speeds.They "reset" while driving at highway speeds.
Approximately 150 miles depending on specific starting and stopping points.
Highway driving tends to be consistently moving forward, whereas city driving is a lot more stop-and-go. Higher speeds are reached on the highway. Highway driving tends to be straight line and long curves, whereas city driving has a lot more turns.
Hi; 2 hours is quit a long time if your driving on the highway, It could lead t0 other damage to the transfer case. If in town driving and you are starting and stopping a lot, It may not seem as bad but remember to take out of gear before stopping at night so it don't freeze in gear. Use it when needed, and it will lead to fewer problems in the long run
About 3 days of driving, depending on your starting and stopping points. The distance by road from Atlanta to LA is 2,175miles,
Stalling at idle? Immediately after starting? While driving? While stopping? Cold or hot engine? What engine do you have?
Need car's weight and stopping power to compute.
