AMSOIL 100% SYNTHETIC MULTI-VEHICLE POWER STEERING FLUID

AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid delivers quiet, responsive steering performance and long-lasting wear protection across a wide range of domestic and import vehicles. It is a direct upgrade over conventional power steering fluids that break down under heat and thicken in cold weather.

Power steering systems operate as hydraulic circuits under constant pressure, cycling fluid through pumps, valves, hoses, and seals hundreds of times per minute. That fluid absorbs heat, fights contamination, and must maintain precise viscosity across a huge temperature range. Conventional fluids lose their protective qualities over time, leading to pump noise, sluggish response, hardened seals, and eventually leaks. Most drivers never think about their power steering fluid until something goes wrong.

ELIMINATES COLD-WEATHER PUMP WHINE
Conventional power steering fluid thickens significantly in cold temperatures, restricting flow through the pump and creating that familiar morning whine or groan when you turn the wheel. AMSOIL Multi-Vehicle Synthetic Power Steering Fluid has a pour point of -51°C (-60°F) and a Brookfield viscosity of just 5,690 cP at -40°C per ASTM D2983 testing. That means it flows freely in extreme cold, providing immediate lubrication and quiet operation on startup, even in northern climates where temperatures regularly drop below zero. If you drive a BMW 3 Series, VW Passat, Subaru Outback, or any vehicle that sits outside overnight in winter, this is the synthetic power steering fluid that stops cold-start pump noise.

PROTECTS AGAINST WEAR AND EXTENDS COMPONENT LIFE
The power steering pump is one of the most mechanically stressed accessories on your engine. Its internal vanes, bearings, and seals rely entirely on the fluid for lubrication. AMSOIL Multi-Vehicle Synthetic Power Steering Fluid produces a Four-Ball Wear Test scar of just 0.46 mm (ASTM D4172, 40 kg, 75°C, 1,200 rpm, 1 hr), demonstrating strong anti-wear film strength under load. That translates directly to less pump wear, longer hose life, and reduced stress on steering rack internals in vehicles like the Mercedes C-Class, Porsche Cayenne, Toyota Tacoma, and Hyundai Sonata.

RESISTS HEAT AND THERMAL BREAKDOWN
Power steering fluid temperatures can spike well above 200°F during sustained driving, parking maneuvers, and heavy-load conditions. Fluid that breaks down under heat forms varnish and deposits that clog valves and degrade seals. This synthetic formulation has a flash point of 230°C (446°F) and a fire point of 250°C (482°F) per ASTM D92, with a viscosity index of 197 (ASTM D2270). That high viscosity index means the fluid maintains stable viscosity across the full operating temperature range rather than thinning out when things get hot. Components stay clean and seals stay conditioned.

KEEPS SEALS SOFT TO PREVENT LEAKS
Hardened, brittle seals are the number one cause of power steering fluid leaks in aging vehicles. Heat and chemical degradation from conventional fluids cause seal materials to shrink and crack over time. AMSOIL Multi-Vehicle Synthetic Power Steering Fluid is formulated to help seals remain soft and pliable, maintaining proper fitment and reducing the risk of leaks. This is especially relevant in higher-mileage Ford F-150s, Chrysler minivans, GM trucks, and European sedans where power steering seal replacement is labor-intensive and expensive.

RESISTS FOAMING FOR CONSISTENT HYDRAULIC RESPONSE
Aerated fluid loses hydraulic efficiency, causing spongy or inconsistent steering feel. AMSOIL Multi-Vehicle Synthetic Power Steering Fluid shows foam tendency results of 0/0, 10/0, 0/0 in ASTM D892 testing across all three sequences. Virtually zero foam means consistent hydraulic pressure and predictable steering response at all temperatures.
