For the engine bay, the 1982 OMNI’s 1.7-liter engine requires 4.0 quarts of oil when the filter is changed. The recommended oil grades include 10W-30, 10W-40, and 10W-50 for various operating temperatures. The oil drain plug should be torqued to 20 foot-pounds to ensure a secure seal without stripping the threads. When selecting a AMSOIL Passenger Car & Light Truck Antifreeze & Coolant, the system holds 5.8 quarts. The AMSOIL Passenger Car & Light Truck Antifreeze & AMSOIL Propylene Glycol Antifreeze and Engine Coolant is an excellent pre-mixed option that is compatible with all cooling system components, including gaskets and hoses. For those who prefer a concentrated formula, the Propylene Glycol Antifreeze allows for custom mixing ratios to achieve desired freeze points and protection levels.
Transmission maintenance varies depending on whether the vehicle is equipped with a manual or automatic gearbox. For automatic transmissions, the initial fill requires 3 quarts, with a total fill capacity of 7.3 quarts for the A404(30TH) or up to 8.9 quarts for the A670 models. The AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is ideal for resisting harmful sludge and promoting smooth shifts. For manual transmissions, the capacity varies by model, generally ranging from 3 pints to 4.4 pints for 4-speed units, while 5-speed transmissions like the A525 hold 2.1 liters. The AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube is formulated to protect brass synchronizers and provide outstanding cold-flow properties, ensuring the gears engage smoothly even in frigid conditions.
The braking and steering systems also benefit from specialized synthetic fluids. The 1982 Dodge OMNI utilizes a DOT 3 hydraulic AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid system, which meets MS-4574 specifications. Upgrading to AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures consistent pedal feel and prevents fluid degradation over time. For the power steering system, the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid reduces friction and helps prevent leaks by keeping seals soft. This fluid offers high-temperature stability, ensuring the steering remains quiet and responsive. In addition to mechanical fluids, the AMSOIL P.i. Performance Improver can be added to the fuel tank to restore engine performance by cleaning fuel injectors and reducing carbon buildup. For vehicle owners who do not drive their OMNI daily, the AMSOIL Gasoline Stabilizer prevents fuel degradation during long storage periods.
About the Vehicle
The 1982 Dodge Omni stands as a significant piece of American automotive history, representing Chrysler’s ambitious entry into the subcompact market during the early 1980s. Introduced in 1978 as a 1979 model, the Omni was part of Chrysler’s “E-Body” platform, sharing its architecture with the Plymouth Horizon. This pairing of vehicles marked a pivotal shift for the company, moving away from the large, fuel-inefficient cars of the 1960s and 70s toward a smaller, more practical design philosophy driven by the regulatory pressures of the era.
Powering the 1982 OMNI was a choice of compact engines, including the 1.7-liter inline-four found in this guide. This engine was designed to balance performance with the fuel economy demands of the time, offering a reliable powertrain for daily commuting. The 1.7-liter variant provided sufficient torque for urban driving while maintaining reasonable fuel consumption figures. The vehicle’s compact footprint made it a favorite for city dwellers, offering easy parking and maneuverability that larger American sedans could not match. Its design also featured a unique “fastback” silhouette, distinguishing it from the more boxy subcompacts of its competitors.
Ownership of a 1982 Dodge Omni in the present day is often a pursuit of enthusiasts who appreciate the raw, unfiltered driving experience of a classic economy car. The Omni’s suspension setup was tuned for a balance of comfort and handling, though owners often seek to upgrade components to further improve ride quality. The build quality of the era varied, making the choice of high-quality lubricants even more critical for preservation. By utilizing top-tier synthetic fluids, owners can mitigate the wear inherent in a vehicle of this vintage, ensuring that the engine, transmission, and cooling systems continue to function smoothly. The Omni remains a beloved icon of the transition from the gas-guzzling 70s to the fuel-efficient modern era, and proper maintenance ensures its legacy continues.
