Mobil ATF D/M is a fully synthetic transmission fluid suitable for use in most power steering systems. Key benefits as a replacement for Volvo Penta fluid include:
- Stable viscosity – Carefully balanced viscometrics maintain stable flow across temperature extremes typically encountered in marine engines. This ensures consistent hydraulic pressure delivery and proper component lubrication.
- Anti-wear protection – Mobil ATF D/M contains special zinc phospholipid compounds to coat metal surfaces. This protects the power steering pump and other moving parts from wear by enhancing boundary lubrication when mixed or boundary lubrication is insufficient.
- Detergent/dispersant additives – Keeps contaminants in suspension and prevents deposit buildup through the use of ashless detergents. This maintains cleanliness within the system to prevent premature degradation or sticking components.
- Seal compatibility – Approved for use with common power steering seal materials such as nitrile rubber, silicone, fluorocarbon, and other popular elastomers. This reduces chance of seal deformation, shrinkage, or leaks.
- High temperature stability – Thermally stable at temperatures over 300°F thanks to synthetic base oils and antioxidants. This resists viscosity breakdown that can lead to pump cavitation and noise.
The key downside is Mobil ATF D/M lacks the precise additive balance required for optimal corrosion protection and friction modification in Volvo Penta systems. Use only as a temporary fill until Volvo Penta fluid can be obtained.
Lucas Oil Power Steering Fluid
Lucas Oil power steering fluid is a popular aftermarket option known for its ability to revitalize seals and stop leaks. Key features as a substitute include:
- Seal conditioners – Proprietary additives in the formula soften and swell seals to stop and prevent leakage. Tests show it can restore shrinking and dried seals to like-new condition. This fixes pesky leaks in aged power steering systems.
- Anti-wear – Includes zinc and phosphorus compounds to protect against metal-to-metal contact under boundary lubrication conditions. This reduces wear of internal pump parts most susceptible to damage.
- Detergents – Extra detergents clean away sludge and contaminants while dispersants keep them in solution. This prevents harmful deposit buildup that can clog flow control valves and orifices.
- Marine corrosion inhibitors – Added rust and corrosion inhibitors protect components from water and saltwater intrusion common in marine environments. This safeguards internal metals against galvanic corrosion.
The tradeoff with Lucas Oil fluid is it utilizes more conventional petroleum base oils versus full synthetics. This may result in decreased thermal stability at high temperatures. Use only temporarily until draining and replacing with OEM specified Volvo Penta fluid.
