Maintaining the health of your 1987 Plymouth Voyager equipped with the 2.2L four-cylinder engine (Engine Code C) requires attention to the specific fluid capacities and formulations designed for this vehicle’s age and design. Proper lubrication is not just about filling reservoirs; it is about protecting aging seals, preventing sludge buildup in older engine blockages, and ensuring smooth transmission operation. The 2.2L engine, a staple of Chrysler’s lineup, benefits significantly from the enhanced thermal stability of synthetic oils, which resist breakdown better than conventional oils in varying climate conditions.

Engine Oil and Filtration for the 2.2L Engine
The heart of the 1987 Plymouth Voyager is its 2.2-liter four-cylinder engine. While originally designed for conventional motor oils, upgrading to a full synthetic formulation yields immediate benefits in terms of engine cleanliness and wear protection. For this specific engine, the recommended viscosity depends on the operating temperature, but synthetic options provide a broader safety net against extreme heat and cold. The engine oil capacity is 4.0 quarts when the filter is replaced, and the oil drain plug should be torqued to 20 ft/lbs.
AMSOIL offers two primary choices for European-style and general use that fit this vehicle’s requirements. The AMSOIL 5W-40 FS 100% Synthetic European Motor Oil is a distinct formula tailored for vehicles with tighter tolerances, often found in European vehicles, but it works exceptionally well here due to its high-quality base oils and additive package. Alternatively, the AMSOIL 5W-40 MS 100% Synthetic European Motor Oil offers a slightly different additive balance that also delivers superior protection. Both oils resist shear breakdown, ensuring the oil maintains its viscosity even under the stop-and-go driving conditions typical for a vehicle of this age.
Filtering the oil is just as critical as using the right oil. The AMSOIL Oil Filter is designed to handle the specific contaminants found in older engines. With a filtering efficiency of 99 percent at 20 microns, it captures fine soot and metal particles that can cause premature wear in cylinder walls and bearings. This is particularly important for a 1987 model, where microscopic damage can accumulate over decades of use. A compatible alternative is the WIX Oil Filter, which also offers premium media improvements over the original equipment filters, ensuring that the new synthetic oil does not get dirty quickly.
Transmission and Cooling Systems
Ensuring the longevity of the 1987 Voyager’s transmission requires a fluid that can handle the thermal stress of an aging system. The automatic transmission fluid capacity varies depending on the specific transmission type, but generally, a total fill requires around 8.9 quarts, while an initial fill is closer to 4 quarts. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing and elevated temperatures. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use, preventing the shudder and harsh shifts often associated with older transmissions.
The AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid serves as an excellent alternative for those seeking a cost-effective option that still delivers top-tier protection. It resists sludge buildup and promotes smooth, shudder-free shifts, which can significantly improve the driving experience. For the cooling system, the 2.2L engine requires a specific volume of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. This AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix that protects all cooling system metals, gaskets, and hoses. Its unique poly-organic acid formulation allows it to remain effective for up to 150,000 miles or five years, reducing the frequency of coolant flushes and helping to prevent overheating issues common in older radiator systems. For a concentrated option, consider the AMSOIL Propylene Glycol Antifreeze and Engine Coolant.
Brake Fluids and Power Steering
Vehicle safety is paramount, especially in a classic vehicle like the Voyager. Over time, AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid can absorb moisture, leading to a lower boiling point and potential brake fade. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is a high-performance solution that ensures excellent ABS and traction-control responsiveness. It maintains a stable viscosity across a wide temperature range, providing consistent pedal feel and stopping power even in severe driving conditions. This fluid meets the specific MS-4574 requirements for hydraulic brake systems found in this era of Chrysler vehicles.
Power steering systems also benefit from synthetic lubrication. The AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid reduces friction within the steering gear and helps keep seals soft to prevent leaks. Older power steering racks can become noisy and leaky as seals harden; this synthetic fluid is formulated to resist heat, extending fluid life and promoting quiet operation. It offers strong anti-wear protection, ensuring that the power steering pump continues to operate smoothly for years to come.
About the Vehicle
The 1987 Plymouth Voyager represents a pivotal moment in automotive history, serving as the pioneer of the modern minivan segment. Introduced by Chrysler, the Voyager (along with the Dodge Caravan) effectively created a new class of family vehicle, combining the utility of a truck with the comfort and handling of a passenger car. Before the Voyager, families had to rely on large station wagons or convert vans converted by third parties, which often lacked comfort. The 1987 model year featured a front-wheel-drive layout, which was revolutionary for a van of this size, offering better traction and fuel economy compared to the rear-wheel-drive predecessors.
Powered by the ubiquitous 2.2-liter four-cylinder engine, the Voyager offered a balance of economy and utility that resonated with consumers. This engine family was known for its simplicity and reliability, making it a staple in fleet operations and family use for decades. The vehicle’s market position was clear: it was the practical choice for growing families needing to transport passengers and cargo without the bulk of a full-size van. The driving character was focused on smoothness and ease of maneuverability, with the front-wheel-drive layout providing predictable handling in rain or snow.
While the 1987 Voyager is a durable vehicle, owners of this classic minivan often face specific maintenance challenges that can be mitigated with the right fluids. One common issue is the hardening of seals in the engine and transmission, which can lead to leaks. Using synthetic motor oils like the AMSOIL 5W-40 FS 100% Synthetic European Motor Oil or AMSOIL 5W-40 MS 100% Synthetic European Motor Oil, along with fluids like the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid helps maintain seal flexibility, preventing these costly leaks. Another prevalent problem in older 2.2L engines is sludge buildup, particularly if the vehicle has been subjected to short-trip driving where the oil never fully heats up to evaporate moisture. AMSOIL’s synthetic oils resist oxidation and sludge formation better than conventional oils, keeping the engine internals cleaner, especially when paired with an AMSOIL Oil Filter or WIX Oil Filter. Additionally, the transmission in these vehicles can sometimes exhibit harsh shifting or shuddering as the fluid degrades. Switching to a high-quality synthetic transmission fluid like the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid can restore smooth operation and extend the life of the transmission bands and clutches. Finally, brake systems in vehicles of this age can suffer from fluid degradation, leading to spongy pedals or reduced braking efficiency, a problem solved by flushing with a high-temperature synthetic brake fluid like the AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid.
