Ok I just got back from the Ol Wallymart, I thought my truck took 6 qrts of oil only to find out it takes 7 (5.4). Anyway I have a 2010 and I am getting ready to change the oil. I bought 5w30w the first time (6qts) and when i went back to get another qrt all the had was 5w20. I bought the motorcraft semi synthetic. Is there going to be an issue mixing 1 qrt of 5-20 with 6 qts of 5-30? I wouldn't think so but thought I would ask.

Thanks.

I would take back the 30 and get all 5w20. That is what is recommended.

Have you checked the owner's manual? I think that our trucks are supposed to use only 5W-20W.
Mixing the two weights should not be a problem if you decide to do that....

Ur fine and using the 30 is ok in the hot Texas climate. I personally would use the 20 in winter and 30 in summer months.

Thanks guys, I will just use it. Not worth the trip back and the hassle. I change it every 3k so it shouldn't be an issue.

Thanks again.
