Engine Oil and Filter Recommendations
The 2004 Chevrolet Tracker with the 2.5L 6-cylinder engine requires a motor oil that can handle the demands of the SOHC design. AMSOIL recommends SAE 5W-30 for all temperatures as the preferred viscosity, though 10W-30 is an option for temperatures above -18°C. The engine holds 5.8 quarts of oil when the filter is included, and the drain plug torque specification is 26 ft/lbs. For those seeking the absolute highest level of protection, AMSOIL Signature Series 5W-30 100% Synthetic Motor Oil is the top choice. This premium fluid offers 75% more engine protection against horsepower loss and wear compared to standard oils and is guaranteed for up to 25,000 miles or one year. Its advanced additives help prevent turbocharger wear and sludge formation, ensuring the engine remains clean and efficient.
For owners who want extended service intervals without the premium price tag of the Signature Series, AMSOIL Extended-Life 5W-30 100% Synthetic Motor Oil provides up to 20,000 miles of protection. This formulation includes enhanced cleaning power to help keep the engine running smoother and longer. It offers 37% more cleaning power than the OE line and helps prevent low-speed pre-ignition (LSPI) events, making it a robust choice for daily driving.
Those who prefer an option that closely mimics the protection levels of original equipment oils while still offering the benefits of synthetic technology will appreciate AMSOIL OE 5W-30 100% Synthetic Motor Oil. This fluid is designed to fight sludge and deposits with a 100% synthetic formulation and has demonstrated zero LSPI events in GM-required tests. It is an excellent choice for tracking vehicles where the manufacturer’s specifications are paramount.
To ensure the oil is properly filtered, the AMSOIL Oil Filter is the ideal companion. It provides a filtering efficiency of 99 percent at 20 microns, allowing for lower restriction which keeps engine parts lubricated. The filter also features a greater capacity for small, wear-causing contaminants, offering extended service life that matches the synthetic oil it is paired with. For those seeking a different brand, the WIX Oil Filter offers premium media that provides improvements over OEM-branded filters, ensuring your engine stays clean.
Transmission and Differential Fluids
The transmission system in your 2004 Tracker varies by drivetrain configuration, but proper lubrication is critical for smooth shifting and longevity. For the automatic transmission (M41 in 4WD or M41 in RWD configurations), the fluid capacity ranges from 2.6 quarts for initial fill to 7.5 quarts for a total fill in 4WD models. The transmission specification has been updated from Dexron II or III to Dexron VI, meaning a high-quality synthetic fluid is essential. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is engineered to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero conditions. It provides reserve protection during heavy use, preventing the fluid from breaking down under stress.
For a more budget-friendly automatic transmission option, AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid offers excellent protection against wear while meeting the fuel efficiency requirements of modern vehicles.
Manual transmission owners should use AMSOIL 5W-30 Manual Synchromesh Transmission Fluid. This fluid is specifically formulated for maximum protection in synchromesh transmissions, reducing friction, heat, and wear. It resists oxidation, acid buildup, and varnish, which helps improve cold-weather shifting and maximizes fuel economy. Whether your Tracker is a 4WD or RWD model, this fluid ensures smooth gear engagement and extended transmission life.
In the transfer case and differentials, gear lube quality is paramount. For the transfer case (GL-4), AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube is an excellent choice. It protects brass synchronizers and has excellent seal compatibility. For the front and rear differentials (GL-5), AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube provides advanced protection against wear and thermal runaway. It is ideal for limited-slip applications due to its friction modifiers. If you prefer a lower viscosity for better fuel economy, AMSOIL SEVERE GEAR® 75W-90 100% Synthetic Gear Lube is another top-tier option that controls operating temperatures and reduces rust and corrosion. For the most demanding environments, AMSOIL SEVERE GEAR® 75W-110 100% Synthetic Gear Lube offers the highest load-carrying capacity.
Cooling System and Brake Fluid
The cooling system in the 2004 Tracker holds 8.5 quarts of coolant. Maintaining the correct antifreeze concentration is vital to prevent overheating and corrosion. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation that provides protection up to 150,000 miles or 5 years. It is phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free, making it safe for all cooling system metals, gaskets, and hoses. For those who prefer to mix their own, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers concentrated protection that greatly surpasses standards for metallic corrosion and erosion.
Brake fluid is another critical safety component. The 2004 Tracker uses hydraulic brake fluid meeting DOT 3 specifications. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness. Its stable viscosity over a wide temperature range ensures consistent braking performance in both hot and cold conditions, giving you confidence in your vehicle’s stopping power.
