1999 bONNEVILLE WITH 98,000 MILES

I had the oil changed today at the dealer. My husband told me the oil was in the garage--he likes to use synthetic oil.

When I got home he told me I used the wrong oil--I used the 5W30 he uses in his Grand Prix instead of the 10W 30 he uses in the Bonneville. Will this hurt the car--We live in Ohio.
