What's the subaru forester oil drain plug size?

You should plan on changing the oil filter in a Subaru Forester at least every 7,500 miles if using full synthetic oil and every 5,000 miles or 6 months if employing conventional lubricants. Raise the vehicle using Ramps or jack stands. Locate the oil drain plug on the underside of the vehicle and release with a 14 mm or 17 mm wrench, depending on year of model. Allow the old lubricant to drain into a pan positioned beneath the plug. Replace the O-ring on the new filter and screw in to replace. The 2.5 liter 4Cylinder engine is equipped with 5.1 US quarts of 0W-20 with a filter. The advantages of using synthetic vs conventional products include better lubrication among moving parts, a longer interval between service appointments and enhanced effectiveness under adverse weather conditions.
