Castrol MAGNATEC Professional OE 5W-40 Engine Oil

Castrol Magnatec Professional OE 5W-40 is a professional engine oil featuring intelligent molecules that cling like a magnet, dramatically reducing engine wear. It is micro filtered and boasts a signature green colour - your guarantee of Professional quality.

This oil has been specially engineered to deliver outstanding wear protection in today’s modern engines. It is formulated to protect modern diesel engines fitted with Diesel Particulate Filters (DPFs) by preventing deposit build up, allowing them to efficiently remove harmful particles from the exhaust.

Instant protection from the moment you turn the key.

Up to 75% of engine wear happens while your engine warms up. When the engine stops, oils drain off critical engine parts, however Castrol Magnatec Professional’s intelligent molecules don’t. They cling to the engine like a magnet providing an extra layer of protection; ready to protect from the moment you turn the key.


Castrol Magnatec Professional OE 5W-40 is suitable for use in automotive petrol and diesel engines where the manufacturer recommends an ACEA C3, API SN/CF or earlier specification 5W-40 lubricant. It is approved for use in vehicles from a wide variety of manufacturers, please refer to the specifications section and your vehicle handbook.

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
