No problem; but test results discussed on "bob the oil guy" web site have demonstrated that Mobil 1 5W-20 provides at least as much protection if not more than their 5W-30 product. There is much overlap in the specifications for viscosity. Any good name brand 5W-20 should provide you with more than adequate service. If you are driving in over 100 degree F pulling a heavy load up hill than a 10W-30 might be a more appropriate viscosity for that use. Common sense and a little knowledge can go a long way.
