Absolutely. 5000k on dino oil would be fine, so synthetics should cause no problems.
Hold the phone ...
Mobil does not recommend Mobil 1 for extended drains. And, unless you live somewhere like Hawaii, where the air temp doesn't vary by much more than 15-degrees all year, I don't recommend a 5000K drain with any conventional oil.
