Castrol EDGE 5W30 Professional Longlife III FAQs Is Castrol EDGE 5W-30 suitable for hybrid cars? This oil is fully compatible with hybrid engines and is a common recommendation for hybrid vehicles in the VAG group lineup, including certain hybrid Golf and Passat models.

It meets the specifications set by Volkswagen (VW 504 00/507 00) and Porsche (C30), and carries the ACEA C3 rating recognised across a wide range of European manufacturers. How often should I change this oil? Follow the service schedule in your owner’s manual. This oil is formulated to support extended drain intervals, but your manufacturer’s guidance always takes priority – particularly if your car uses a condition-based service indicator. Can I mix Castrol EDGE 5W-30 with another engine oil? Technically, yes, but we don’t recommend it. Mixing oils of different brands or formulations can dilute the performance of both. If you’re topping up between changes, try to use the same product where possible. Does this oil help with fuel economy? The low-viscosity 5W-30 grade reduces friction inside the engine, which is one of the ways modern oils contribute to modest fuel savings compared to heavier grades.Volume: 5 Litres
