Castrol 5W40 engine oil - fully synthetic oil with universal application

Castrol 5W40 is a fully synthetic oil with universal application for gasoline and diesel engines without strict Low SAPS requirements, including those with gas systems. Castrol is a British brand with over 100 years of history in lubricants. The EDGE, MAGNATEC and GTX series cover the requirements of most European manufacturers.

5W40 maintains a stable oil film under high loads and temperatures and is therefore one of the most used viscosities in Bulgaria.

Approvals and standards

Before purchasing, check the oil approvals with the vehicle manufacturer's requirements - for example, ACEA A3/B4, VW 502.00/505.00, MB 229.3. Full specifications for each product are listed in its description.

Tips for changing

Change the oil when the engine is warm and always together with the oil filter. After changing, check the level on the dipstick and top up if necessary - the level should be between the two marks.
