2 Lubricating oil Quality ClassesWhich lubricating oil qualities complying with DQC are required, also depending on the engine output and operatingconditions, is set out in Technical Circular 0199-99-3002 and in the operating instructions of the various engine series.Below is a brief description of the oil Quality Classes according to DQC and the engines they are suitable for.

• DQC I-02 Lowest oil quality, sometimes reduced oil change intervals• DQC II-05 Standard quality, usually used in engines with open crankcase ventilation • DQC III-05 High-performance diesel engine oil, used in engines with closed crankcase ventilation and

for high-performance engines• DQC IV-05 Ultra high-performance diesel engine oil for engines with highest level of output with closed

crankcase ventilation

Engine oils that are released under the higher DQC classifications may also be used in the next lower DQC classes.

The engine oil properties must not change during normal storage periods and must be miscible in any ratio with otherengine oils released by DEUTZ. No precipitation, layering or opacity may occur in these mixtures. The engine oils mustbe free of any solid particles and water.

Engine oils permitted under this standard must not contain any ingredients which are classified as prohibited orundesirable under VDA Guideline 232-101. The designation and quantity of ingredients which have to be declared under VDA Guideline 232-101 must be shown.

2.1 Lubricating oil Quality Classes DQC I-02 and DQC II-05Lubricating oils in the lubricating oil Quality Class DQC I-02 and DQC II-05 may be released by DEUTZ if therequirements for the following classifications are complied with:

DEUTZ lubricating oil Quality Class DQC I-02ACEA E2-96 or API CF or API CF-4

DEUTZ lubricating oil Quality Class DQC II-05ACEA E3-96 or ACEA E4-99 or ACEA E5-02 or ACEA E6-04 or ACEA E7-04 or API CG-4 or API CH-4 or API CI-4 or API CJ-4 or DHD-1

Lubricating oil of Quality Classes DQC I-02 and DQC II-05 which comply with these ACEA or API classifications maybe used in DEUTZ engines without having a specific DEUTZ release.Lubricating oils which have been tested in a DEUTZ release test and have been released by DEUTZ in writing may belisted in the datasheets or other publications by the lubricating oil manufacturers as complying with lubricating oilQuality Class DQC I-02 or DQC II-05. Such claims shall not be used for oils which have not been released.

Their viscosity classes may be one of the following SAE classes:0W-30, 5W-30, 10W-30, 15W-300W-40, 5W-40, 10W-40, 15W-4020W-50

(Choice of viscosity class depending on the ambient temperatures)

Single-grade oils are also permissible for DQC I-02 and DQC II-05 in terms of TR 0199-99-3002 specifications.

H 0685-3 8906-85-03, Page 3

2.2 Lubricating oil Quality Classes DQC III-05 and DQC IV-05Lubricating oil complying with DEUTZ Quality Class DQC III-05 and DQC IV-05 may be released by DEUTZ it theappropriate release requirements have been fulfilled.The requirements for DQC III-05 and DQC IV-05 oils are listed in Appendix B. The limit values shown in the tables arefor DQC III-05 according to ACEA E7-04 and for DQC IV-05 according to ACEA E7-04 and ACEA E4-99 but in partwith higher requirements. These requirements have been defined in terms of low turbocharger pollution when usingclosed ventilation, as well as for improved oxidation stability under high thermial lubricating oil load.

Their viscosity classes may be one of the following SAE classes:0W-30, 5W-300W-40, 5W-40, 10W-40

(Choice of viscosity class depending on the ambient temperatures)

For DQC III-05 the SAE classes 10W-30, 15W-30 and 15W-40 will also be accepted additionally if values drop belowthe specified limits with sufficient safety. This will not usually be the case with the oils in these SAE classes presently onthe market but could be possible with regard to newly developed oils in principle.

Lubricating oil manufacturers may list released lubricating oils in datasheets or other publications as complying withlubricating oil Quality Classes DQC III-05 or DQC IV-05. Such claims shall not be used for oils which have not beenreleased.

With his signature the applicant confirms that all the results and data given in the application are correct, that theconditions described in this Company Standard are accepted and the applicant undertakes to observe the conditions. Ifthe applicant is guilty of specifying incorrect results and data and DEUTZ grants a release according to this CompanyStandard and engine damage is incurred as a result of the oil quality, the applicant is obliged to compensate DEUTZ’slosses in case of such damage and to release them from third party claims. If the applicant is guilty of violating theconditions of this Company Standard and DEUTZ incurs damage as a result, the applicant is obliged to compensateDEUTZ for such damages and to release them from claims by third parties.The applicant will normally only market one product worldwide under one brand name, which has been tested andreleased by DEUTZ. The oil code will indicate clearly the identity of the engine oil here. In exceptional cases, theapplicant may market different formulations in different countries under the same product designation with different oilcodes, provided DEUTZ has tested and released each formulation. In this case the applicant undertakes to sell only oneproduct with this formulation in each country.

The applicant undertakes not to make any recommendations concerning use in DEUTZ engines (e.g. with regard to oilchange intervals, viscosity classes etc.) if these do not comply with the recommendations made by DEUTZ.

The application papers and the oil sample must be sent to the following address:

DEUTZ AGDept. "Abgas und Betriebsstoffe"Ottostr. 1D-51149 KölnGermany

The forms with the manufacturer's details, the safety datasheets and the IR spectrum must also be sent by e-mail to lubricants.de@deutz.com

DEUTZ AG will use all the data provided by the applicant exclusively for their own purposes and for assessment of therelease application.

A release is normally valid for 3 years from the written validation by DEUTZ and becomes invalid automatically at theend of this period. The right to use the DQC mark always expires when the validity expires. The applicant is advised tosubmit a renewal application in good time.The applicant undertakes to inform DEUTZ in writing of any change of the composition of the oil at least 3 months inadvance. If any engine damage is caused by a change in the quality of the lubricating oil and the applicant has notadvised DEUTZ in advance in writing of such a change by the above-mentioned deadline, the applicant undertakes tocompensate DEUTZ for any damage and to release the company from any claims by third parties.DEUTZ reserves the right to withdraw a release at any time if there are important reasons. Important reasons in this sense are especially (but not only):

- Any change in the quality of the lubricating oil or its composition (base oil or additives) for the engine oil towhich the release applies

- Insolvency or imminent insolvency of the lubricating oil supplier- Improper use of the DEUTZ DQC trade mark

Should the composition of an oil be changed, the release process will be the same as for the first release of the changedoil.

3.2 Release of original oils and package releasesPackage releases in the sense of this Company Standard refer to additive packages of additive manufacturers which areused for different viscosity classes and different oil manufacturing, whereby the additives for this are often modifiedslightly. Modifications both to the basic oils and the additives are only permissible insofar as they are describedaccording to Base Oil Interchange (BOI), Viscosity Grade Read Across (VGRA) and Minor Modification Rules in theATIEL/ATC Code of Practice as well as in API 1509 and in the ACC Code of Practice. The described modificationsapply both with regard to the transferability of the package release to oils for which the oil manufacturer refers to the

H 0685-3 8906-85-03, Page 5

package release of the additive manufacturer and with regard to the validity of engine test results in slightly varied oilcompositions. The complete application (appendix C) must be filled in for releases of original oils and package releases.

3.3 Release of oils with reference to package releasesThe manufacturer of a lubricating oil who uses an additive package which already has a package release from DEUTZmust fill in the first 3 pages of the application (appendix C). He must also prove that the modifications in the formulationof the oil to be released observe the permissible modifications described in chapter 3.2 in comparison with the oildescribed in the package release.

3.4 Release of reblended oilsA reblended oil in the sense of this Company Standard refers to an oil already released by DEUTZ which has been madeby another manufacturer according to the same recipe (base oil and additives). For the release of a reblended oil in accordance with DQC III-05 or DQC IV-05, the first 3 pages of the application(appendix C) must be submitted.

3.5 Release of rebranded oilsFor the purposes of this Company Standard, a rebranded oil is one which DEUTZ has released which is to be resold bythe original manufacturer and released under a different brand name. For the release of a rebranded oil under DQC III-05 or DQC IV-05 an application as in Appendix D must be submitted aswell as a confirmation from the original manufacturer of the lubricating oil confirming that the oil for which the releaseis applied for is a rebrand of an oil which has already been released by DEUTZ AG.

3.6 Release informationThe release for lubricating oils according to DEUTZ DQC is in the form of a written release declaration given to thelubricating oil manufacturer. The lubricating oil brand name in data sheets, publications and oil containers must exactlymatch the name of the lubricating oil and the DEUTZ lubricating oil quality class in the release declaration.A list of the currently released lubricating oils has been published on the Internet under www.deutz.com in the section”Service >> Oil, Lubricants,Diagnosis”.

3.7 Release costsA fee will be charged for testing and awarding the release as well as for the right to use the DEUTZ DQC mark.A written release will only be awarded by DEUTZ AG when the appropriate fee has been paid.The charges can be requested from DEUTZ when making an application.
