There's no difference between 5W-30 and 10W-30 until the temps get below 20*F. Then the 10w-30 begins to get thicker.
I agree that the OP likely has an oil leak somewhere. Either at the lower intake (the side rails blow out if not correctly installed), the oil pan, or at the rear main seal.

I have driven well over 1,000,000 miles in 3 of these cars.
3 things I swear by with them.
1: change the oil each 3,000 miles
2:5W30 you never need to add oil between the 3,000 miles.(10W30 you will need to add oil)
3: The faster you average the better mileage you get.(adds 100 miles to tank if you are at 100 MPH)
