I have a 2018 Subaru Forester with the 2.5L engine.I know it takes 5.1qrts but when I changed the oil I put 5qrts in and it read on the dipstick I believe right in the middle.If I top it off with the 1oz I doubt that it would bring it up to below the top notch on the dipstick.Should I add oil or just leave it?Thanks Joe
