ok, so I've hard my truck for a little while now (like 4 weeks) and I need to get an oil change. Keep in mind this is my first truck and I am used to cars that take 5w30.

I've got the 5.8L V8 Gas engine. Should I use 10W30 or 5W30?

Thanks for any kind of help!

I *think* I use 10w30.

 

Its starting to get chilly out. Now is when I switch from 10/40 to 5/30. Sometimes in the summer I use 5/30, when I "use" the oil at work
