Maintaining the 2008 Dodge Caliber with a 1.8-liter engine requires more than just following a standard service schedule; it demands the use of fluids specifically formulated to handle the engine’s design characteristics and the driving conditions typical of a compact car. Proper lubrication ensures that the engine operates smoothly, minimizes wear during cold starts, and extends the service life of critical components like the transmission and cooling system. Whether you are driving through extreme heat or navigating cold winters, using the correct viscosity and chemical formulation is essential for optimal performance.

Engine Oil and Filtration Specifications
The heart of the 2008 Dodge Caliber with the 1.8L engine requires a specific viscosity to ensure proper lubrication under various operating conditions. For this engine, AMSOIL recommends using a 5W-20 viscosity motor oil. The fluid capacity for the 1.8L engine, including the filter change, is 4.5 quarts. It is crucial to refill and then check the oil level after the service is complete to ensure the engine is not overfilled or underfilled. The drain plug torque specification is 30 ft/lbs, which should be adhered to during any maintenance procedure to prevent leaks or stripped threads.
AMSOIL Signature Series 5W-20 is the top-tier choice for this vehicle, offering unsurpassed engine protection and up to 25,000 miles of service. This oil is engineered to be 75% more effective against horsepower loss and wear compared to industry standards. For drivers who prefer a slightly different service interval or budget consideration, the Extended-Life 5W-20 provides 20,000 miles of guaranteed protection and features 37% more cleaning power to help the engine run smoother for longer. If your vehicle is nearing the OEM mileage interval or you prefer a standard synthetic option, the OE 5W-20 is an excellent choice that fights sludge and deposits. For Calibers with over 75,000 miles, the High-Mileage 5W-20 formula is specifically tuned with enhanced anti-wear additives and a boosted detergent package to reduce sludge by 67% and help engines last longer.
The filtration system works in tandem with the oil to protect the engine. AMSOIL offers the EA15K50 oil filter, which provides 99% filtering efficiency at 20 microns. This filter allows for lower restriction, keeping engine parts lubricated, and offers greater capacity for small, wear-causing contaminants than competing filters. Alternatively, the WIX Oil Filter 57060 is a premium option that uses media offering improvements over original equipment manufacturer-branded filters. Both options ensure that the oil circulating through the engine remains clean, protecting critical components from abrasive particles.
Transmission and Cooling System Maintenance
The transmission system in the 2008 Dodge Caliber varies depending on the model, with some equipped with a CVT2 automatic transmission and others with a manual transmission. For CVT2 units, the total fill capacity is 8.6 quarts, with an initial fill of 7.4 quarts. The 100% Synthetic CVT Fluid is highly recommended for these transmissions, providing exceptional metal-to-metal frictional properties that outperform standard fluids. This fluid remains fluid in sub-zero temperatures and withstands the heat and stress of challenging driving conditions.
For models with manual transmissions, the capacity is 5.7 pints. The AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid or the Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid can be used for these manual units. Both fluids are designed to protect against wear, resist harmful sludge, and promote smooth, shudder-free shifts. The OE version is particularly noted for its excellent cold-weather performance and ability to guard against leaks.
The cooling system is another critical area for the 1.8L engine, requiring a total capacity of 7.2 quarts of coolant. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a pre-mixed 50/50 formulation that protects all cooling system metals, gaskets, and hoses. It is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, making it compatible with all other antifreeze colors. For those who prefer a concentrated coolant, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a versatile option that protects for up to 150,000 miles or 5 years. This propylene glycol formulation is non-toxic and environmentally safer, offering protection against metallic corrosion and erosion that greatly surpasses standard requirements.
Brake Fluid and Other Essential Fluids
Brake safety is paramount for any vehicle, and the 2008 Dodge Caliber utilizes a hydraulic brake fluid system that requires DOT 3 fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an excellent upgrade, providing excellent ABS and traction-control responsiveness. Its stable viscosity over a wide temperature range ensures consistent braking performance regardless of the weather conditions.
For power steering systems that require Mopar P/N 05013457AA (MS9602 specification), the AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid or OE Multi-Vehicle fluid serves as an effective replacement. These fluids withstand the rigors of heavy towing and elevated temperatures while remaining fluid in sub-zero conditions.
