Castrol MAGNATEC 10W-40 A3/B4 Engine Oil – 1L • 15F7CA
Castrol MAGNATEC 10W-40 A3/B4 engine oil for Mazda MX-5 Mk1 / NA and Mk2 / NB petrol engines and other petrol or diesel vehicles requiring an SAE 10W-40 ACEA A3/B4 / API SP lubricant.
Castrol MAGNATEC 10W-40 A/B is a part-synthetic engine oil developed to provide protection from engine start-up and during normal driving. Castrol's MAGNATEC technology is designed so protective molecules cling to critical engine components, helping maintain a protective layer when conventional oil would otherwise drain back into the sump.
For the Mazda MX-5 Mk1 / NA and Mk2 / NB generations, 10W-40 meeting ACEA A3/B4 is an established service specification, making this product particularly well suited to routine maintenance of 1.6 and 1.8 petrol models.

Other items to consider: When carrying out a full engine-oil service, consider replacing the engine oil filter and drain-plug sealing washer at the same time. Check the required service-fill quantity before ordering the total amount of oil required.
Why Castrol? Castrol MAGNATEC is formulated specifically around protection during the repeated start-up, warm-up and stop-start conditions encountered in everyday driving.
