What year, make, model, and engine.
Depending on the engine, I would do a short OCI(no more than 3000 miles) with Mobil 1 10w30 or 10W-40 High Mileage or Valvoline synthetic Valvoline MaxLife 10w30. I would use a Wix filter.
After that , I would use Valvoline 10w30 or 10W-40 Maxlife blend and a Wix filter.
High Mileage oil is more than just detergents. It has a better 100C cSt, better HTHS, more anti wear agents, more antioxidants, and for sure has seal conditioners.
