Castrol Edge 5W-30 is a full synthetic motor oil built around the brand's fluid Titanium technology, aimed at engines that run hot or under high pressure. It carries a dexos license and is recommended by several car manufacturers, so it fits many modern gasoline engines that call for a 5W-30. Castrol claims it resists viscosity breakdown three times better than leading conventional oils and than Mobil 1, and that it limits metal-to-metal contact and deposit buildup. It suits drivers who want a widely available synthetic for harder-working engines rather than a budget conventional oil.
