The updated 2007 Peugeot 308 introduced a selection of new PSA Group engines, the most popular of which were 1.6- and 2.0-litre HDi turbo-diesels and 1.6-litre VTi petrol engines. Castrol points out that every engine in the current generation Peugoet 308 was designed to run on fully-synthetic, low viscosity 5W-30 engine oil.
It’s important that vehicle technicians top-up these vehicles with the correct oil formulation. Anything other than the recommended fully-synthetic 5W-30 C2 formulation will not have the relevant PSA Peugeot Citroen B71 2290 approval (including higher viscosity oils, such as 10W-40), thereby invalidating the manufacturer warranty, and may reduce the efficiency, performance and longevity of the engine.
Those models fitted with diesel particulate filters – any of the HDi FAP engines – also require low SAPs C2 specification oils, to ensure the filter doesn’t become blocked.
The oil change intervals for the current Peugeot 308 vary from 12,500 miles for 1.6 HDi engines to 20,000 miles for other models in the range – more than most motorists drive in a year. Workshops could consider offering customers a one-litre bottle of approved 5W-30 oil in case the motorist needs to top-up their car’s engine oil between visits to the workshop. This can also help customer satisfaction and retention, as the workshop can demonstrate that they have their customers’ best interests at heart. Castrol Magnatec 5W-30 C2 has been approved for all engines in the 308 range, including those fitted with a DPF, for which low SAPs C2 oils are recommended.
