There's no point raising the cold weight, it will just mean the oil is thicker on a cold start. If you are seeing high temperatures regularly then you could consider an oil with a higher hot weight, e.g. 5W40. The second weight is measured at 210F. The 5W30 is going to be at it's ideal weight at 210F where as 5W40 will need 230-240F to be in it's sweet spot, and you'd have more protection at 260F.
