Below are the AMSOIL oil and filter recommendations for your 1984 Porsche 928 with the 4.7L 8-Cylinder.
1984 PORSCHE 928 4.7L 8-CYLINDER ENGINE CODE 81E X
The 1984 Porsche 928 is the grand tourer that Porsche built to replace the 911, and the 4.7L V8 up front is what made it different. Where the 911 put its engine in the tail, the 928 used a front-engine, rear-transaxle layout that gave it near-perfect weight distribution and long-legged cruising ability.
The 928's V8 is a robust, oversquare design that Porsche refined for over a decade. It is an engine that rewards proper maintenance, and oil is at the top of the list. The engine runs hot in its tightly packed bay, and its chain-driven valvetrain depends on clean oil with stable viscosity.
AMSOIL's European formula is built for engines like this, with the thermal stability a hard-working V8 needs. For a 1984 928, it keeps the 928's V8 healthy whether the car is a weekend cruiser or a daily driver.
The 1984 Porsche 928 4.7L 8-Cylinder requires 5W-40 full synthetic motor oil. Capacity is 7.9 quarts including filter.
