Cold Start – How It Impacts the Engine When Starting the Car

By: Olivia Anderson

Why is a cold start important?

Technically, a cold start increases the temperature of the engine and warms the oil in the engine. Oil is the critical fluid in your engine, keeping all moving parts properly lubricated and performing at their best. If the engine has not been used for a long period, from parking at night to starting it in the morning, most of the oil will settle to the bottom of the engine. There is still residual oil on the top of the machine, but this is not enough protection. Especially if you run the engine hard from the beginning. For this reason, it is important to pump the oil into the engine for a few seconds to heat it.

The heating of the oil depends on its viscosity or how easy it is to pour at a certain temperature. Low temperatures increase viscosity, reduce flow ability, and limit the ability to form a thin protective layer on moving parts. Using the cold start function to warm up the engine warms the oil and makes it flow better.

What should you do on a cold start?

After starting, let the engine idle for a few seconds before driving the luxury car rental in Dubai. This gives the oil more time to circulate and lubricate all moving parts. Here are some tips to keep in mind when starting a cold engine.

Do not rev or race the engine when it is cold. If you thought it was cool to rev a cold engine, think again. You may not realize it at first, but keeping a cold engine running increases friction and causes more damage. If you have an older car with a carbureted engine, don’t forget to close the choke on a cold start. Otherwise, the engine may stall repeatedly until it warms up. Watch your driving speed. Drive slowly for the first few minutes until the engine reaches the desired operating temperature. When the engine is cold, so is the automatic transmission. Keep this in mind when starting a cold engine.


This is the last resort when all other options have been exhausted. If your car has a jumper cable but you don’t know what you’re doing, it’s not a good idea to try it as you could injure yourself or damage your car.

With both vehicles idling and engines off, connect one end of the red jumper cable to the positive battery post of one vehicle and the other end to the positive battery post of the other vehicle. Then connect one end of the black jumper cable to the negative battery post of the other car and the other end to the unpainted metal surface of your car. Then start the other car’s engine and let it run for a few minutes before starting your own.

If that, unfortunately, doesn’t work, it’s time to call Roadside Assistance from car rental near me.

The clutch plummets when the ignition is turned on

Another sneaky trick that sometimes works is to dip the clutch a bit when you twist the ignition. This reduces the work the battery has to do and gives the car a fighting chance to start even with a cold engine.

Keep the fuel tank full

We all know that an empty gas tank will cause your car to stall, but did you also know that starting a cold car first thing in the morning will consume 40% more fuel than normal? If you’re driving home from work tomorrow night and your fuel tank looks a little low, you might want to fill it up before putting it off for the night. I’ll be right back the next morning.

 Use the right oil

There may be different engine oils specifically available for use in cold climates. Check your owner’s manual to make sure you’re using one that’s suitable for cold weather conditions, and if not, invest in new oil.

Turn off everything

Standard electrical accessories such as headlights, heaters, and radios all use battery power. So if you turn all of these off before starting the Bentley car rental in Dubai, the battery is more likely to start the engine. After the engine starts, let it run for a while before turning on these accessories. Otherwise, you risk destroying the battery again.

Will cold start damage the engine?

Yes and no. With regular oil changes and following the tips above, a cold start will not damage your engine. However, if you don’t change the oil often and insist on revving a cold engine to warm it up, you’re doing more harm than good.
