CASTROL MAGNATEC 10W-40 A/B

Why Choose Castrol?

Castrol MAGNATEC 10W-40 A/B is suitable for use in automotive petrol and diesel vehicles where the manufacturer recommends an ACEA A3/B4, API SP 10W-40 lubricant, and is designed to offer excellent protection across the various conditions of modern driving.

Castrol MAGNATEC's unique breakthrough DUALOCK molecules attach to engine components and lock together into a lubricating protective film that is effective from a cold start. These DUALOCK molecules help to reduce warm-up wear on critical engine parts and support longevity during frequent short-journey use, making this product ideal for applications where heavy traffic conditions could otherwise cause significant wear. Castrol MAGNATEC 10W-40 A/B offers strong and consistent performance across extended drain intervals and reliable protection across a range of temperatures.

MAGNATEC 10W-40 A/B is excellent for engineers and fleet managers in the UK because it blends everyday versatility with manufacturer-level approvals. For mixed-fleet operations, older high-mileage petrol or diesel cars, or modern vehicles that demand robust start-stop protection under UK traffic conditions, this oil offers an excellent balance of performance and versatility. At Broughton Lubricants, we also offer complementary product lines such as classic car oils, fully synthetic grades, brake fluids and a comprehensive range of products for a fleet's full vehicle maintenance programme.
