Inside Line: Castrol

The BMW E90 3-Series (2005-2011) replaced the BMW E45, consolidating the range of available engine sizes and introducing a smaller capacity 1.6-litre engine alongside the 2.0-litre, 2.5-litre and 3.0-litre petrol engines, and 2.0-litre and 3.0-litre diesel engines.

Castrol points out that every engine in the E90 3-Series range was designed to run on fully-synthetic, low viscosity Castrol EDGE 0W-30 engine oil, the only oil actively recommended by BMW.  The oil filler cap even acknowledges as much, serving as a reminder to motorists and workshops which lubricant BMW points out is best for the car.

It’s important that vehicle technicians top-up these vehicles with the correct oil formulation.  Any lubricant lacking the relevant BMW Longlife-04 approval may invalidate any remaining manufacturer warranty, and may reduce the efficiency, performance and longevity of the engine.

BMW recommends oil change intervals of 15,000 miles for every model in the E90 3-Series range, though oil change intervals may vary according to driving conditions.  Workshops should consider offering customers a one-litre bottle of the BMW-recommended Castrol EDGE 0W-30 oil, in case the motorist needs to top-up their car’s oil between workshop visits.  This can also help customer satisfaction and retention, as the workshop can demonstrate that they have their customers’ best interests at heart.
