These lubricating oils have better temperature and oxidation stability as well as relatively low cold vicosity. Since some processes which are relevant for determining the lubricating oil change times are largely dependent on the oil quality (e.g.
the infiltration of soot and other contamination), the oil change time for synthetic lubricating oils may not be increased in relation to the specifications on lubricating oil change intervals. Biodegradable lubricating oils may be used in DEUTZ engines if they meet the requirements of this operating manual. Lubricating oils are classified by DEUTZ according to their performance and quality class (DQC: DEUTZ Quality Class). Essentially, the following applies: the higher the quality class (DQC I, II, III, IV), the more effective/the better quality the lubricating oil is. lubricating oil flows, depending on the temperature.
The lubricating oil viscosity only has a small influ- ence and effect on the quality of the oil. Lubricating oils according to other comparable spec- ifications can be used as long as they meet DEUTZ requirements.

The specific engine performances which have increased constantly over the last few years lead to an increased thermal load on the lubricating oil.
The lubricating oil is also more exposed to contamination due to reduced oil com- sumption and longer oil change intervals. For this reason it is necessary to observe the requirements and recommendations described in this operating manual in order not to shorten the life of the engine. Lubricating oils always consist of a base oil and an additive package. The most important tasks of a lu- bricating oil (e.g. wear protection, corrosion protec- tion, neutralisation of acids from combustion products, prevention of coke and soot deposits on the engine parts) are assumed by the additives. The properties of the base oil are also decisive for the quality of the product, e.g.
with regard to thermal load capacity. In principle, all engine oils of the same specification can be mixed. However, mixing of engine oils should be avoided because the worst properties of the mix- ture are always dominant. The lubricating oils approved by DEUTZ have been thoroughly tested for all engine applications. The ac- tive ingredients they contain are compatible with each other. Therefore, the use of additives for lubri- cating oils is not permitted in DEUTZ engines. The lubricating oil quality has a considerable influ- ence on the life, performance and thus also on the costs-effectiveness of the engine. It basically applies that:
The better the lubricating oil quality, the better these properties.
