oil weight question

My wj 4.0 I6 calls for 5w30 in the winter and 10w30 in the summer. I've been following this for the past 2 years. Should I continue to do so, or is 5w30 ok year round? I run Mobil 1 full synthetic. Thanks for any advice!

Re: oil weight question

5w30 is ok all year round, I used to do like you in my old 4.0 ZJ, but after a while stuck with 5w30. This will be better for cold starts, and will be the same weight at operating temperature.

Re: oil weight question

Thanks Aaron, cold starts are the reason I want to go with 5w30 year round. Just wanted to make sure it wouldnt damage anything. I think ill go 5w30 year round now... I figured thinner oil would be better because of the wear upon start ups, winter or summer.
Thanks again
