SHE A R PROT EC T ION Today's tighter piston‑to‑liner clearances and powerful forces of piston rings in motion cause permanent viscosity loss or "shear" in an engine oil. This can lead to decreased film strength and increased wear and oil consumption. The exceptional shear control of Castrol Hypuron • Castrol Hypuron 10W‑30 Advanced Formula's stay‑in‑grade technology comes from Castrol's radial polymer, which is found in viscosity improver. • Castrol Hypuron Advanced Formula 10W‑30 stays‑in‑grade longer than conventional CJ‑4 15W‑40 diesel oils while maintaining strong film strength. • Many engine oils use viscosity improvers that employ "long‑chain polymers." Once the shearing forces within an engine attack a "long chain polymer,"permanent viscosity loss is likely. • Once viscosity is lost, oil thinning, reduced film strength and increased oil consumption can result.
