Measures for slightly sludged engine:
Oil and filter change. Purge engine, i.e. normal engine operation
in neutral, or while driving, using oil from Sheet 229.3, 228.3, or
228.5. Drain off scavenging oil after purging process (approx. 1
hour). Repeat purging process if necessary. Refill using engine oil
from Sheet 229.3, or 229.1. The first oil change after clearing the
sludge should be performed after approx. 10,000 km or beforehand;
when doing so use engine oil from Sheet 229.3.
Measures for severely sludged engine:
Engines with severe oil sludging and caking onto engine parts
and into bores have to be dismantled and mechanically cleaned.
Tough sludge residue must not enter the clean side of the oil circuit,
as otherwise, e.g. the piston oil spray and the hydraulic
compensation elements may have their functionality impaired. Refill
using engine oil from Sheet 229.3, or 229.1.
The first oil change after sludging should be performed after approx.
10,000 km; when doing so use engine oil from
Sheet 229.3.
Warranty/goodwill regulations
If in combination with engine oil sludging a warranty/goodwill claim is
submitted, then a regular documentation of maintenance must be
presented. The ASSYST printout is to be filed carefully for further
reference.
Oil sludging in combination with an exceeded oil change interval, or
because of special additives in the fuel/engine oil are costs to be
borne by the customer.
