Lucas Oil advises that power steering issues on early Astra and Zafira models without electric pumps need not always lead to an expensive replacement programme. They can be treated with Lucas Oil Power Steering Stop Leak. It's an effective treatment for hard spots and tightness in worn rack and pinions.
Those models fitted with electric power steering require Lucas Oil Power Steering Fluid With Conditioners. This is a synthetic-based fluid with foam inhibitors. It lubricates springs and valves, conditions seals, eases sluggish operational issues and stops small leaks.
