When should I change the engine oil in my 2006 Subaru Forester Car?
The older an engine, the weaker the engine gets. Older engines are often classified as engines in cars made before 2010 or engines with more than 100,000 mileage. Whichever comes first. It is often advised to change the oil of older engines as soon as you can, preferable after every 6 months or 4000 – 7,000 miles depending on the state of the engine.
Cars with high mileage or older engines tend to have oil leakage as a result of the seals wearing out, and as such, high mileage engine oil has additives that help protect the seals and lessen the oil league.

The recommended engine oil for the 2006 Subaru Forester is the 5W-30 Conventional Oil with 4.4 Quarts Capacity.

What is 5W-30 Oil?
5W-30 conventional oil is one of the most popular engine oil in the world, as it is commonly used in petrol and diesel engines. The 5w30 oil ranges from low to high viscosity grade. I.e from 5 to 30.
The “W” stands for “winter,” the number “5” before the W stands for the oil’s viscosity (or thickness) at cold temperatures (hence the W), and the number after the “W” stands for the viscosity at higher temperatures. I.e. when the engine is running, during summer or in hotter regions.
5w-30 oil works in temperatures as low as -30ºC and as high as 35ºC. This makes it a great choice to use if you’re in a tropical region or places with high-temperature changes. The 5W-30 works well for cars driving in the cold region because of its low viscosity. It can flow freely when the engine is started at a low temperature, and is also great for long travels because of its adaptability to heat.
