Went to pick up some oil last night and all I saw were boxes and boxes of 10w30. There were only 2 boxes of 5w30 avail, so I grabbed one. What's the difference between the two? Aren't 5w + 10w just the temperatures they can work well in?
the 10w is thicker and the 5w is thinner...
Most shops use 10w30 during the colder weather and 5w30 during warmer seasons.
