Should I change to 10w30 oil?

Hi there. My car currently has 212k miles on it and I have noticed the past couple months that every time I fill up the oil (use 5w30 valvolinr high mileage) within a week or so, I have to add more oil since the reservoir it's almost empty. Also I do oil changes very often every 3,500 miles. Could changing to 10w30 be the best move? And what oil out in the market would be the best option? Thank you

You use what is in the owners manual & on the oil fill cap

At 212K there is no fix, only a new motor

30 is 30 once warmed up,so different oil won't stop your problem

If your eating 4 four quarts every couple weeks,get a newer car

Where is the oil going? Try a new PCV valve.
