I've come to see that my Forester oil dipstick is read differently than other cars; I have to pull it out and let it set for ~4 minutes before reinserting it for the reading. So at gas station, do the tank fill-up during the 4 minute wait.
And at your oil change place ask them, up front in person before you give them the keys, if you can observe the drain of the old oil, because of concerns about oil quality in your car. They'll let you; if don't then go somewhere else. Make your own oil sludge judgement, even hi caliber shops sometimes fudge on 'upcoming disaster warnings.'
