Castrol Magnatec Stop-Start 5W-30 C2 is a passenger car and light commercial vehicle engine oil designed for petrol and diesel vehicles that experience frequent stop-start operation, particularly those requiring a low SAPS lubricant. It is suitable for use in automotive gasoline and diesel engines where the manufacturer recommends an ACEA C2 or API SN 5W-30, and is also suitable for Peugeot and Citroen vehicles requiring a 5W-30 lubricant approved to PSA B71 2290 specification, and Fiat vehicles requiring a 5W-30 that meets Fiat 9.55535-S1.
The oil is formulated with Castrol's 'intelligent molecules' chemistry, which is designed to cling to engine parts when the oil drains down between starts and form a self-healing layer that protects at each of the critical stages of stop-start driving. Castrol cites the industry OM646LA test as showing significantly less wear in stop-start operation versus comparable lubricants.
Approvals and performance levels include ACEA C2; API SN; and PSA Approval B71 2290.
The 20-litre pack format is suited to single-machine top-up and small workshop service. Store sealed in the original packaging, in a clean, dry area away from extremes of temperature, to preserve product performance over its shelf life.
Today even a normal driver can stop and start as many as 18,000 times a year. And all that idling in traffic or waiting at junctions causes microscopic wear in your engine.
In the latest industry test, New Castrol MAGNATEC STOP-START 5W-30 C2 gives significantly less wear in STOP-START operation*.
New Castrol MAGNATEC STOP-START 5W-30 has intelligent molecules that cling, and form a self-healing layer so it’s always ready to protect at each of the critical stages of stop-start driving.
Castrol MAGNATEC STOP-START 5W-30 C2. Instant Protection From The Moment You Start. Every Time You Start.
*As tested in the industry OM646LA test*
