In the workshop manual servicing schedule, which is only available to garage and workshop technicians rather than vehicle owners, PSA states that: ‘an engine oil is defined by a grade, an approval according to the specification laid down by the ACEA (European Automobile Manufacturer’s Association), and one or more of approvals according to the manufacturer’s specification (Manufacturer’s Recommendation)’ (Fig. 4).

There is still no direct link to ACEA sequences, although the text does caution that a C2 must not be used in engines earlier than the year 2000.

The grade of the engine oil is defined by the SAE (Society of Automotive Engineers), and according to the technical specifications laid down in the ACEA engine oil sequences, Peugeot cars need very good oil.

Looking further down the page of the schedule, Peugeot/Citroen finally makes a set of recommendations about which oil to use which are similar to those contained in the owner’s servicing and warranty booklet for the vehicle, based on a particular brand name and a viscosity linked to a Peugeot/Citroen/DS standard (Fig. 5).

Overall it is perhaps not unsurprising to see how motorists get confused when the right type of engine lubricant is complicated enough for professional mechanics to decipher. That’s where online databases can be of real use. These databases are powered by the technical knowledge and expertise of large companies such as OATS based in the UK, or Olyslager based in the Netherlands, who spend many thousands of hours each year ploughing through numerous owner manuals and service documents to identify the right products for a vehicle just by entering the registration.

Depending on the database, these sometimes offer a choice of brands so that garages and workshops can make their own selection, depending on local availability or their personal preference. PSA is by no means alone in how they present lubricant information. If they can retain a vehicle owner’s business within their dealership network, then that makes sense from an economic and brand control perspective.

However, independent workshops and garages must be given clear information to enable them to make a decision on which oil to use when servicing customer vehicles.

Using market general formulations or products from reputable brands and stockists means using the right lubricant for the vehicle which still meets the requirements of the manufacturer.

ACEA is not mentioned here, despite having mentioned it previously. At the bottom of the table, a statement says ‘*or any other oil complying with Peugeot/Citroen/ DS standards’. But these are not listed as to what they might be, and no further reference is provided. There is also no link back to the Peugeot 208 and the engine oil standard that is required by the particular vehicle.

The servicing schedule does go on to provide a list of countries ranked by climate conditions and whether they are temperate, cold or arduous. For European fuel types, a listing is provided which links the engine standard type to the viscosity of the lubricant.

As part of the lubricants industry, we all have a role to play in helping to educate users about making the right choice of lubricant for each vehicle.
