Castrol EDGE is our strongest and most advanced range of engine oils yet. Its unique Fluid Strength Technology strengthens the oil to reduce metal-to-metal contact. In a test of the oil’s strength across a variety of engine speeds, the Castrol EDGE range average metal to metal contact is 40% lower than a leading competitor.
We asked a third party laboratory to test the Castrol EDGE range using our Maximum Endurance Test and on this test Castrol EDGE was proven to be on average 35% stronger for longer compared to a competitor brand from another major lubricant supplier.
