When selecting the correct motor oil for your 1997 Buick Riviera, you have several high-performance options tailored to your driving habits and the vehicle’s mileage. The engine requires a 10W-30 viscosity grade, particularly for temperatures above -18°C (0°F), though 5W-30 is a suitable alternative for colder climates below 16°C (60°F). The total capacity for an oil change, including the oil filter, is 4.5 quarts. After refilling, it is essential to check the oil level to ensure it is at the correct mark. The oil drain plug should be torqued to 32 ft/lbs for optimal security.
The AMSOIL Signature Series 10W-30 stands out as a premier choice, providing up to 25,000 miles of protection and 75% more engine protection against horsepower loss compared to standard oils. It is trusted by professional engine builders and effectively protects turbochargers. If you prefer a slightly shorter service interval, the Extended-Life 10W-30 offers 20,000 miles of guaranteed protection with enhanced cleaning power to keep the engine running smoother. For those seeking a cost-effective solution that still outperforms conventional oils, the OE 10W-30 is an excellent alternative, formulated to fight sludge and deposits while meeting modern OEM requirements. Vehicles with over 75,000 miles will benefit significantly from the High-Mileage 10W-30, which features a unique chemistry designed to boost detergents, reduce sludge by 67%, and help engines last longer.
Filter selection is just as critical as the oil itself. The AMSOIL Oil Filter (EA15K29-EA) is engineered to allow lower restriction while maintaining a filtering efficiency of 99% at 20 microns. Its greater capacity for small, wear-causing contaminants helps reduce engine wear and offers extended service life, matching the durability of the synthetic oils. For those who prefer a well-regarded aftermarket option, the WIX Oil Filter (51040-EA) offers premium media improvements over OEM filters, ensuring reliable filtration for the Riviera’s V6 engine.
Cooling System and Transmission Care
Keeping the cooling system of the Riviera in top condition prevents overheating and corrosion. The coolant capacity for this vehicle is substantial, at 13.2 quarts. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a 50/50 pre-mix formulation that provides up to 150,000 miles or 5 years of protection. It is free from phosphates, nitrates, and silicates, making it compatible with all other antifreeze and coolant colors. For those who prefer a concentrated solution, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers protection up to 150,000 miles (or 240,000 km) and greatly surpasses standards for metallic corrosion and erosion.
The 1997 Riviera is equipped with an automatic transmission, specifically the 4T60-E or 4T65-E models. These transmissions rely on a total fill of 13.4 quarts for a complete flush, though an initial fill requires 7.4 quarts. It is important to note that the manufacturer’s specification has been updated from Dexron II or III to Dexron VI per a Technical Service Bulletin. AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is designed to withstand heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use. The OE Fuel-Efficient version offers a similar level of protection, ensuring the transmission operates smoothly and resists wear.
Braking, Steering, and Additional Maintenance
Safety systems require consistent performance to ensure driver confidence. The 1997 Riviera utilizes a hydraulic brake system requiring DOT 3 fluid. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent responsiveness in ABS and traction-control systems. It maintains stable viscosity over a wide temperature range, ensuring consistent braking power in both hot and cold conditions. For the power steering system, the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid is highly recommended. It reduces friction, helps seals remain soft to prevent leaks, and resists heat for long fluid life, all while providing strong anti-wear protection.
Seasonal storage or long periods of inactivity can be tough on older vehicles. For these situations, the AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup. The AMSOIL Engine Fogging Oil is an effective rust preventive designed to protect internal engine components during storage. To maintain engine cleanliness and performance between oil changes, the AMSOIL P.i.® Performance Improver Gasoline Additive can restore up to 14% horsepower and clean fuel injectors. The AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor further lubricates the fuel system and upper cylinders. For general maintenance, the AMSOIL Synthetic Multi-Purpose Grease offers long-term performance with outstanding low-temperature pumpability. Additional protection against the elements can be found in the AMSOIL Heavy-Duty Metal Protector, which forms a long-lasting wax-like coating against rust and corrosion.
Keeping the Riviera looking its best is also part of comprehensive care. The AMSOIL Silicone Spray provides a dry lubricating film ideal for rubber surfaces, protecting against cracking. For cleaning, the AMSOIL Heavy-Duty Degreaser quickly dissolves oil, tar, and grime, while the Power Foam® Carburetor and Induction-System Cleaner removes deposits to maximize horsepower. The AMSOIL Miracle Wash Waterless Wash and Wax Spray allows for a quick shine with no soap or water required.
