For owners seeking a high-quality aftermarket option, the WIX Oil Filter offers premium media that improves upon OEM-branded filters, ensuring reliable filtration for the Camaro’s engine block.
Lubricating the Transmission and Drivetrain
Proper transmission maintenance is key to preventing costly repairs. The 1986 Camaro with the 2.5L engine utilizes a 4L60 automatic transmission for automatic configurations, or a manual transmission for stick-shift models. For the automatic unit, the capacity is 11.5 quarts for a total fill, with an initial fill requirement of 5 quarts. It is worth noting that the specification for this transmission has been updated from Dexron II or III to Dexron VI. The manual transmission, specifically the M39 5-speed variant, requires a capacity of 6.6 pints for both standard and limited-slip differentials.
To maintain optimal performance, the AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid is a top recommendation. It is designed to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. The fluid remains fluid in sub-zero temperatures and provides reserve protection during heavy use. For a more economical solution, the AMSOIL OE Fuel-Efficient 100% Synthetic Automatic Transmission Fluid protects against wear while promoting smooth shifts and resisting harmful sludge. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid and AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid are also viable options for various applications, offering excellent cold-weather performance and leak protection.
For the differential, the standard rear differential and limited-slip rear differential both require a GL-5 lubricant. The AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube is specifically suited for these applications, containing friction modifiers for limited-slip differentials. This lube helps control thermal runaway and rust, while also reducing operating temperatures to extend the life of seals and equipment.
