Engine Oil Specifications and Selection
For the 2008 Mazda MAZDA3 with the 2.0L engine, the required motor oil viscosity is 5W-20 across all temperature ranges. The oil capacity for the engine, including a filter replacement, is 4.5 quarts. It is crucial to refill the oil to the correct level and check the dipstick after refilling to ensure optimal lubrication. The drain plug torque specification should be maintained between 22 and 30 ft/lbs to prevent leaks or damage to the pan threads.
Selecting the right synthetic oil allows for longer intervals between changes, reduced friction, and better protection during cold starts. The AMSOIL Signature Series 5W-20 100% Synthetic Motor Oil is the premier option for those seeking the maximum possible protection, boasting 75% more resistance against horsepower loss and wear compared to conventional oils. For owners looking for a balance of performance and value, the AMSOIL Extended-Life formulation provides extended service intervals up to 20,000 miles with superior cleaning power. If you prefer an oil that outperforms conventional options while meeting standard service expectations, the AMSOIL OE Motor Oil is an excellent choice.
Owners of higher-mileage vehicles will find significant benefits in the AMSOIL 5W-20 High-Mileage Motor Oil. With over 75,000 miles, engines can suffer from sludge and increased wear. This specific formulation includes boosted detergents and dispersants that reduce sludge by 67%, helping the engine last longer and perform better. It guarantees protection for 12,000 miles or one year, whichever comes first.
Filtration and Air Intake Maintenance
Clean oil is vital, and the filter is the component responsible for keeping contaminants out of circulation. The AMSOIL Oil Filter (Part EA15K51) is engineered to provide a filtering efficiency of 99 percent at 20 microns. It offers greater capacity for small, wear-causing contaminants than competing filters, helping to reduce engine wear and allowing lower restriction to keep parts lubricated. This filter supports extended service life when used with AMSOIL synthetic motor oil.
For those who prefer an alternative filtration brand, the WIX Oil Filter (Part 51348) features premium media that offers improvements over original equipment manufacturer-branded filters. Additionally, maintaining clean airflow is essential for fuel efficiency and engine power. The WIX Air Filter (Part 42612) provides high-quality filtration for the air intake system, protecting the engine from dust, dirt, and debris that can cause premature wear.
Antifreeze and Cooling System Care
The cooling system in the 2008 MAZDA3 requires a specific fluid capacity depending on the heater configuration. With the heater, the capacity is 7.3 quarts, and without it, the capacity is 7.9 quarts. Using the correct antifreeze and coolant prevents freezing, boiling, and corrosion, ensuring the engine operates at the optimal temperature.
The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is an ethylene glycol, phosphate-free, and nitrate-free formulation that exceeds original equipment manufacturer requirements. It offers protection for up to 150,000 miles or 5 years. For those who prefer a concentrated product that allows for precise mixing ratios, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant provides up to 150,000 miles of protection in passenger cars and light trucks while greatly surpassing standards for metallic corrosion and erosion.
Transmission and Gear Lubes
Proper fluid maintenance extends the life of both automatic and manual transmissions. For the 2008 MAZDA3 automatic transmission (SL027), the total fill capacity is 7.6 quarts. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain while remaining fluid in sub-zero temperatures. Alternatively, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid guards against leaks and promotes smooth, shudder-free shifts.
If your vehicle is equipped with a manual transmission (G35M-R), the fluid capacity is 6.1 pints. The AMSOIL 75W-90 Manual Transmission & Transaxle Gear Lube is friction-modified to protect brass synchronizers and provides outstanding cold-flow properties. For limited-slip applications or those seeking extreme protection, the AMSOIL SEVERE GEAR® 80W-90 and SEVERE GEAR® 75W-90 100% Synthetic Gear Lube contain friction modifiers and control thermal runaway to reduce operating temperatures and extend equipment life.
Brake Fluid and Power Steering
Brake fluid should be changed regularly to maintain hydraulic responsiveness. The 2008 MAZDA3 utilizes a DOT 3 hydraulic brake fluid system. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness with a stable viscosity over a wide temperature range.
For the power steering system, which often utilizes DEXRON-III Automatic Transmission Fluid, using the AMSOIL Signature Series or OE Multi-Vehicle ATF ensures smooth operation and protection against wear and sludge.
