Why does white smoke come out of my exhaust when I start it?

The causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating.

What causes white smoke when starting a diesel engine?

Worn, damaged, or defective valve stem seals or piston rings can leak oil into the combustion chamber, which will then mix with the fuel and create a white or gray exhaust smoke when burnt. In the case of a bad piston ring, the engine may also start to lose power due to a lack of compression.

How do you know if your Turbo has gone?

If you notice that your car isn’t accelerating as powerfully as it used to, or is slow to react to your input, this might be a sign that your turbo is failing. Similarly, a turbocharged car that struggles to maintain high speeds or isn’t able to reach speeds it once could may be experiencing turbo failure.

Should you let a turbo car warm up?

No, it does not need to be warmed up before driving. No modern vehicle with fuel injection needs to be warmed up before driving, turbo, supercharger or not. If the ambient temperature is in the above freezing range, let the vehicle idle long enough for oil to fully circulate and get into the turbo.

Are turbo engines high maintenance?

Do turbocharged engines require more maintenance? The short answer is yes. A turbocharged engine will not forgive low oil level, poor-quality oil or extended intervals between oil changes. Most turbocharged cars need high-quality synthetic oil and have shorter maintenance intervals.

Does a turbo engine need synthetic oil?

Synthetic oils are almost always required by modern turbo-car manufacturers. Failure to use it will void the warranty.

Do I really need synthetic oil for my car?

Yes. Some engines require the use of synthetic oil, but most do not. However, synthetic motor oil can be used in place of conventional oil even if the vehicle manufacturer does not require it.

When should you put synthetic oil in your car?

Certain brands recommend you have your oil changed every 3000 or 5000 miles. Other recommendations range from 7500 to 20,000 miles. Other factors that influence the time between oil changes include driving conditions and your driving style.
