Diploma in Classic Lubrication: ZDDP, Viscosities and Running-In
Online postgraduate diploma of 800 hours in classic engine lubrication: 8 modules covering classic engine tribology, oils and viscosity, ZDDP and anti-wear additives, classifications and selection, running-in of rebuilt engines, oil analysis and diagnosis, and maintenance and storage, with an assigned technical tutor.
Diploma in Classic Lubrication: ZDDP, Viscosities and Running-In — studying from Ireland
Ireland has an active heritage vehicle and classic machinery community, supported by clubs, restoration workshops and specialist suppliers serving classic cars, motorcycles and agricultural equipment. Engineering skills in this area combine historical knowledge with modern techniques in fabrication, materials and diagnostics. Restoration work is often linked to heritage conservation and museum collections, and classic vehicles operate under national roadworthiness and vehicle registration rules. Professional bodies and enthusiast organisations help maintain standards and knowledge across the sector.
Fees for Ireland: €1,490 (Euro), with instalments and employer sponsorship available.

Questions from Ireland
Is there a recognised professional body in Ireland for classic vehicle restoration?
Classic vehicle restoration in Ireland is largely a craft and hobby sector, supported by enthusiast clubs and heritage bodies rather than a regulated professional title. SEIUM's qualifications are private and not accredited by any national body, so they do not confer membership or formal recognition. Check the requirements of any club or body you wish to join.
Would Irish restoration businesses or employers value this qualification?
Restoration businesses in Ireland often rely on hands-on skill, reputation and portfolio work. A private online qualification may add to your CV, but employers decide for themselves whether it is relevant. Your final project can help show your capability, though there is no guarantee of any outcome.
Can I study this part-time while keeping my current commitments?
Yes, the programme is 100% online and taught in English, so you can study from home around existing commitments. Durations are 300, 800 or 1,900 hours depending on the course, so plan your schedule accordingly. Fees can be paid in instalments, and each student has an assigned technical tutor.

How you'll learn
A 100% online programme on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so you can combine it with your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Microsoft Excel, Minitab and Ansys Granta Selector, in free, academic or evaluation versions. Testing is studied through real procedures: running in a flat-tappet engine, elemental analysis of oils and kinematic viscosity measurement. Assessment is continuous by module, plus the final project.
Standards covered: SAE J300, SAE J306, API 1509, ACEA oil sequences, ASTM D445, ASTM D4951, ASTM D5185.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
