This guide is for owners of vintage cars with worm-type steering boxes. It details the Millers Oils Vintage Worm Drive Steering Box Lubricant, designed to significantly reduce stiffness and improve steering feel. While highly effective, it's specifically formulated for older steering systems and may not be suitable for modern applications. Key features include a high viscosity mineral base, low friction additives, and extensive testing by Rolls-Royce and Bentley engineers.

This oil is specifically formulated for vintage car steering boxes, particularly those that utilize a worm-type mechanism.
No, this oil is not designed for modern power steering systems. It is a high-viscosity mineral oil intended for older, manual steering boxes.
The amount of oil required varies depending on the specific vehicle and steering box capacity. Consult your vehicle's workshop manual for the recommended capacity and filling procedure.
It is recommended to check the steering box oil level periodically as part of your vehicle's regular maintenance schedule, or if you notice any changes in steering feel.
The primary benefit is the reduction of stiffness and stickiness in vintage worm-type steering boxes, leading to a significant improvement in steering ease and feel, as validated by expert testing.
As a mineral-based oil designed for vintage applications, it is generally compatible with the types of rubber seals commonly found in older steering systems. However, always refer to your vehicle's specific service information if possible.
High viscosity means the oil is thicker and flows more slowly. In vintage steering boxes, this provides better lubrication and sealing, especially at operating temperatures, and helps to reduce the 'sloppiness' or 'play' that can develop over time.
Ensure the correct amount of oil was added and that the oil has had time to circulate. Check for any obvious binding or mechanical issues within the steering system itself. The steering box may require rebuilding if wear is significant.
Check the filler plug and surrounding seals for tightness. If leaks persist, the steering box seals may be degraded and require replacement. This product is a lubricant, not a seal conditioner.
This may indicate internal wear or moisture ingress. Consider flushing the system (if appropriate for the specific steering box design) and refilling with fresh lubricant. A mechanic may need to inspect the steering box.
Setup: This lubricant is designed to be added to the steering box reservoir. The process typically involves locating the steering box, ensuring the vehicle is level, and carefully topping up the reservoir to the specified level. Always consult your vehicle's workshop manual for the precise location of the steering box filler plug and the correct oil level mark. Use a clean funnel to prevent contamination.
Compatibility: Primarily designed for vintage car steering boxes, especially those with a worm-type mechanism. It is a mineral-based oil and is generally compatible with the seals and materials found in vehicles from the 1940s through to the 1970s. It is *not* recommended for use in modern power steering systems or steering boxes with different internal mechanisms.
Care: Store the bottle in a cool, dry place away from direct sunlight. Ensure the cap is securely tightened after use to prevent contamination. Regularly check the steering box oil level as part of your vehicle's routine maintenance, especially if you notice any increased stiffness in the steering. While the oil itself is designed for longevity, the overall health of the steering box will influence how often it needs attention.
