I know of no reason why it would not be a good match...what does your owner's manual call for? If it calls for a 5W-30 I am even more convinced that it would work for you.

10w-30 Summer 5W-30 Winter I'm using DELO 400 15w-40 now, was going to use DELO 400 10w-30 this winter however I found GC on sale for $3.99, so I bought 7 quarts.
