It is the best of both worlds. Easier flow on startup and less startup wear, yet it is still a 30 weight at full engine temperture.I don't know much about oil. Should I use 0W-30 instead of 10W-30? Is it good? Is it bad? Is it better in colder or warmer weather?
Note: I'm in Chicago so I get it all, cold winters and hot summers.
You use it year around. In my opinion, 10w30 is just not needed. 5w30 is the standard and even up in Canada they have 10w30 on the cap and there is not way in hell I am starting up my car at -25c with 10w30 in it.Thank you DESIREE, Chase300 and Northern 300C.
DESIREE: yes, I do have my owner's manual. It (and my oil cap) do say 10W-30. That's what I've been using since I've had my car (About a year). I was only asking about 0W-30 because I saw it at the store and I read the lable and it said it can be used on Chrysler vehicles that use 10W-30. That's why I came on here to ask for more information about it.
So overall, what I'm understanding is that 0W-30 is better for colder temperatures. Seeing how winter is over, I guess I have no real need for it.
