Hello from Wilmington, NC
'17 Forester Touring - w/o Eyesight and Navigation. Add me to list of dummies that mistook the CVT drain plug for the engine oil drain plug. Fortunately, I recognized that green is not the color of engine oil, and I got the plug back in after losing only a quart. Manual says CVT's take 12.6 quarts, but the service manager said it is actually more than 16 quarts, when you add in the torque converter. Took it to the dealer and had the lost quart replaced. Road test showed no problems.
Changed engine oil after only 500 miles, to replace the "Subaru" oil (Idemitsu is the actual manufacturer) with AmsOil Signature Series 0W-20. Reason: Idemitsu oil has a relatively high vaporization rate- almost 40% higher than AmsOil. That's why Idemitsu synthetic has a change cycle of 6,000 miles and AmsOil's is 25,000 miles or one year. The industry measure for vaporization is the NOACK number. Worth noting that Mobil 1 and Castrol won't disclose their NOACK number, but it can be inferred from their change cycle of 15,000 miles. Got the AmsOil at "wholesale" since my son has an account with them. No sales tax, and if the order is large enough, no shipping.
"The NOACK Volatility Test, otherwise known as ASTM D-5800, determines the evaporation loss of lubricants in high-temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions." Source: Wikipedia.
Could not drain all the engine oil out using my Pela vacuum pump. Drained the rest out (about 2 quarts) through the oil pan drain (after my screw up with the CVT drain.) There apparently is a little sump in the oil pan that the Pela tube can't reach. Engine oil drain plug is accessed by removing a small oval, plastic panel secured by 4 fasteners, only one of which is threaded - the others are expansion type tabs.
