Mazda RX7 Engine Specs
The Mazda RX7 is a legendary sports car that has gained a cult following over the years. One of the key factors that contributed to its popularity is its impressive engine performance. In this article, we will delve into the engine specifications of the Mazda RX7, including its configuration, oil specs, and service intervals.
Engine Configuration
The Mazda RX7 is equipped with a rotary engine, also known as a Wankel engine. Unlike traditional piston engines, the rotary engine operates on a unique principle. It features a triangular rotor that rotates within a housing, creating combustion chambers as it moves. This design allows for a compact and lightweight engine with high power output.
The RX7’s rotary engine comes in different generations, each with its own improvements and advancements. The most notable generations include the Series 1 (SA22C), Series 2 (FC3S), and Series 3 (FD3S). The Series 3 RX7, which was produced from 1992 to 2002, is often regarded as the pinnacle of rotary engine technology.
Engine Oil Specs & Service Intervals
Proper engine oil is crucial for maintaining the performance and longevity of any vehicle, including the Mazda RX7. Here are the recommended engine oil specifications for the RX7:
– Oil Type: It is recommended to use a high-quality synthetic oil with a viscosity rating of 10W-30 or 10W-40. Synthetic oils offer better protection and lubrication, especially for high-performance engines like the RX7’s rotary engine.
– Oil Capacity: The RX7’s engine oil capacity varies depending on the generation and specific model. Generally, it ranges from around 4.5 to 5.5 liters. It is important to refer to the owner’s manual or consult with a Mazda dealership to determine the exact oil capacity for your specific RX7 model.
– Service Intervals: Regular oil changes are essential for maintaining the health of the engine. For the Mazda RX7, it is recommended to change the engine oil every 3,000 to 5,000 miles or every 3 to 6 months, whichever comes first. However, it is important to note that driving conditions and personal preferences may affect the frequency of oil changes. If you frequently drive the RX7 under demanding conditions, such as track days or high-speed driving, more frequent oil changes may be necessary.
