Just drained the factory fill from our 14 Forester and replaced it with Kendall GT-1 Full Syn 0w20. The only location I have been able to source the Kendall is online and my local Wally World only carried 0w20 in Mobil 1 up until recently, which I will not use. Now, they have started to stock PP 0w20 in the 5 quart jugs. So, my dilemma now is which do I want to use? Any Subaru owners out there that have used both Kendall and PP? I am sure that both will work just fine, but any real world experience would be helpful.
