Are there any downsides to auto stop start?
It bears repeating that there are no real downsides to the auto stop-start function besides being annoying. Besides a hardly noticeable lag upon restarting the vehicle and the frequent rumbling of the engine starting up, the auto stop-start system won’t harm your engine or your starter.
What happens when STOP START does not kick in?
Obviously, more stationary time means more fuel saved. There are also occasions when stop-start will not kick in, for example if the engine is cold, the system is less likely to intervene, to allow the engine to warm up fully.
How does auto stop start affect your mpg?
While it is hard to measure the specific effect that auto stop-start systems have on MPG, it is clear that they do save fuel. Your car burns significantly more fuel idling than it needs to start the engine.
How many stop start events can a car go through?
“A normal car without automatic stop-start can be expected to go through up to 50,000 stop-start events during its lifetime,” says Gerhard Arnold, who is responsible for bearing design at Federal Mogul. That’s a big jump and one that poses major challenges to the durability and life of the engine’s bearings.

When to turn off the engine in a car?
According to a study conducted by the Society of American Engineers, it is beneficial to turn your car’s engine off if it is going to be idling for at least seven seconds. Within that range of time, enough fuel is saved to start the car once more, meaning that any time spent with the engine off over that seven-second mark will be fuel saved.
Why do cars start and stop all the time?
While well-intentioned, this gas-saving measure has rubbed plenty of drivers the wrong way. The frequent starting and stopping of the engine, especially on larger vehicles like the F-150 and the Super Duty, becomes grating to drivers who live in urban areas.
