Should I up the weight of motor oil in the hot months? 2013 Hyundai Sonata
My 2013 Hyundai Sonata calls for 5W20 weight all year, would it make sense to increase the weight slightly in July & August. I'm looking for other opinions.
you can go up to 5w30 safely and I would recommend a synthetic for best performance.
If your car is not using oil I would not worry. I use 5W-20 year round in my work truck with no issues in 188,000 miles.
