What is the lifespan of a Subaru horizontally opposed engine?
2 Answers
If used correctly and properly maintained, a Subaru horizontally opposed engine can last over 300,000 kilometers without issues. Horizontally opposed engines have higher requirements for engine oil. If your vehicle is equipped with this type of engine, it's essential to change the oil regularly and use high-quality oil. Here is some relevant information about engine oil: 1. Introduction: Engine oil is referred to as the lifeblood of the engine. Without oil, the engine cannot operate properly. 2. Functions: Engine oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat within the engine. During operation, the oil forms a protective film on the surfaces of engine components, preventing direct contact and friction between parts.
I drove a Subaru Forester for twelve years, and the engine was still running smoothly, with the odometer surpassing 250,000 kilometers. The horizontally opposed engine design reduces vibration and lowers the center of gravity, which might suggest a longer lifespan compared to conventional engines. But the key was my strict adherence to changing the oil and filter every six months and avoiding prolonged high-speed driving. From online discussions, most owners agree that with proper maintenance, hitting 200,000 kilometers is no problem. However, neglecting oil passage cleaning can lead to lubrication issues, causing the engine to retire early. Regular maintenance really saves money and hassle, and replacing parts isn’t expensive either.
