Full synthetic, not sure if I would worry too much. Based on a number of photos here, I wouldn't worry much about it, not at your miles. If you're not short tripping then I am dubious about problems.
Unfortunately, the vehicle sees lots of short tripping. Live in a small town. When we go "out of town" it is 75 miles minimum.
I think this is the reason right here. Combine the short trips with the cold weather and it's a recipe for sludge. Shorter oci schedules might be the best way forward since longer drives are not in the cards.
