As car owners, we've all been told to turn off our engines to conserve fuel, reduce emissions, and prevent damage. But is idling your car really as bad as we've been led to believe? In this article, we'll delve into the facts and myths surrounding idling your car, and explore the impact it has on your engine.

The History of Idling

Idling, or letting your car's engine run for an extended period, has been a common practice for decades. In the past, cars were designed to idle for longer periods without suffering any negative consequences. However, with the advent of modern engines and stricter emissions regulations, the need to idle has decreased significantly.

The Myths About Idling

There are several myths surrounding idling that need to be debunked. One of the most common myths is that idling causes damage to your engine. While it's true that prolonged idling can lead to increased wear and tear on your engine, the impact is typically minimal. In fact, many modern engines are designed to run for extended periods without suffering any significant damage.

Another myth is that idling causes your car to consume more fuel. While it's true that idling can waste fuel, the impact is typically small. In fact, idling for short periods can actually be more fuel-efficient than restarting your engine multiple times.

The Truth About Idling

So, is idling really as bad as we've been led to believe? The answer is no. Idling, in and of itself, is not inherently bad for your engine. However, prolonged idling can lead to increased wear and tear on your engine, which can ultimately reduce its lifespan.

Idling can also cause your car to consume more fuel, which can increase your operating costs. However, the impact is typically small, and idling for short periods can actually be more fuel-efficient than restarting your engine multiple times.

When to Idle

So, when is it okay to idle your car? There are several situations in which idling is necessary or recommended. For example:

In extreme cold weather, idling can help to warm up your engine and get your car moving more efficiently.

In heavy traffic or stop-and-go driving, idling can help to reduce wear and tear on your engine.

In areas with high altitude or extreme temperatures, idling can help to reduce the strain on your engine.

Conclusion

In conclusion, idling your car is not inherently bad for your engine. However, prolonged idling can lead to increased wear and tear, which can ultimately reduce your engine's lifespan. By understanding the facts and myths surrounding idling, you can make informed decisions about when to idle and how to reduce the impact on your engine.

Final Verdict

Idling your car is not a cause for concern, but it's not something to be taken lightly either. By being mindful of the impact of idling on your engine and taking steps to reduce wear and tear, you can help to extend the life of your engine and keep your car running smoothly.

Don’t do it on a hemi. Goodbye lifters.

Although I do agree with most of this video. The exception is many of the modern engines have major issues with their valvetrains. Idling lowers the oil pressure, and the lower RPM does not allow as much windage [oil mist splashed from the spinning of the crankshaft] to assist in the lubrication of the camshaft and roller lifters. An example is the Hemi Motors, Ford 7.3 Gas and many others. I do not believe in remote start in these vehicles and any amount of idling period. Research your engine and see if there are issues with the camshaft and roller lifters before idling extensively.

I used to deliver newspapers so I idled A LOT. 6 nights a week for probably 3 hours of idling time per night, After about a year of that I started having overheating problems and eventually blew a head gasket. That wasn't fun.

so what’s the best car that can idle in heat weather

@ave649

If idling damages car engines, then we must be damaging engines when we drive during stop-go rush hour driving. They are built to idle. In hot weather, shift to neutral to cool the transmission when you stop. In the winter, always leave the car in gear to keep the transmission warm.
