The fourth-generation Volkswagen Polo was unveiled in 2002 with a range of 1.2-, 1.4-, and 1.6-litre petrol engines and 1.4- and 1.9-litre diesel engines.
Castrol points out that every engine in the Volkswagen Polo Mk4 range can run on fully-synthetic Castrol EDGE 5W-30 engine oil. The oil filler cap even carries a Castrol recommendation, serving to remind motorists and workshops what the best lubricant is for their engine.
It’s important that vehicle technicians top-up these vehicles with the correct oil specification. Technicians should note that older models within the range, those which pre-date the Polo’s 2006 facelift, can also run on Castrol EDGE 5W-40 engine oil in petrol and non-DPF diesel engine models on time/distance servicing. The more modern engines fitted to later models (2006-09) on variable servicing, or with DPF fitted, need to be filled with lower-viscosity Castrol EDGE 5W-30.
Any lubricant lacking the relevant Volkswagen Group approvals may ultimately reduce the efficiency, performance and longevity of the engine.
The service intervals for the Mk4 Polo are variable up to a maximum 19,000 miles, or two years in between oil changes – more than most motorists drive in a year. Workshops should therefore consider offering customers a one-litre bottle of engine oil in case they need 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.
