My suggestion would be to stick with 5w-20 (Shell Helix Ultra, ZIC, Kixx, etc.).
Total Quartz 9000 Future Series 5w-30 is another great oil. You may choose it too. Its "Value for money" Oil.
Whichever brand you choose, ensure that is it reputed, offers fully synthetic oil meeting API SN / SN +, ILSAC GF-5 criteria, and is 100% genuine and original.
