3.7 Oil Question

Hey guys and gals. On my 09 3.7 V6, I've been running syntetic since the first oil change at approximatly 4,500 miles (When the car told me to change) and I have been using Mobil 1 10W-30 since it is cheaper to buy in a 5 quart container than the 5W-20 which my parts store only sells in 1 quart containers for $7 a pop! The Jeep manual recommends 5W-20, so I was wondering what any adverse effects the 10W-30 may have. I've noticed that the Hemi guys have to use the 5W-20 for the MDS to work, but the V6 is a much simpler engine so I didn't think that it would be that big of a deal.
