High oil consumption on Skoda Octavia with 1.8 TSI engine

High oil consumption on 1.8 TSI engines is a common thing. Such motors are installed on both the Skoda Superb and the Volkswagen Passat, and on these models they also consume a lot of oil. True, this problem only applies to the CDAB engine version. Other versions - BZB and CDAA consume oil much more modestly.

The Octavia instruction manual says that the allowable oil consumption is about half a liter per 1,000 kilometers. At the same time, an engine consumption of more than 600 ml indicates its malfunction or incorrect operation.

Most often, increased oil consumption is in the engines of cars manufactured in 2009-2010. On cars manufactured in 2011 and younger, changes have been made to these engines so that oil consumption does not exceed the norm.

Under warranty, the problem can be solved by replacing the piston group.

The reasons for the increased consumption may be the following:

The running-in of a new car has not been passed or passed with violations. During the break-in period, increased consumption - up to 0.5 l / 1000 km - is a normal phenomenon.

Turbocharged engines are not well adapted to long idling (for example, in a traffic jam) and at too high speeds (on the highway). This may result in increased oil consumption.

In addition, the oil level should be checked as often as possible and topped up if necessary. The low oil level light should not come on.

You can try to reduce consumption by changing engine oil to a higher quality one (Motul, Liqui Moli). It also helps to fill in oil with a different tolerance level (instead of 504 - 502).

Other options, for example, installing a different type of oil separator, judging by the reviews of the owners, do not give a result.
