Yes, this is an acceptable weight for your Blazer. Do not fall for the 3,000 mile oil change myth. That is a waste of oil and money. Change your oil according to the manufactures recommendations. On your Blazer that is probably 5,000 miles. Use a quality filter such as an AC/Delco, Purolator, or Wix.
In the summer you may want to use a oil that is a little thicher 10w-40 and in the winter use 5w-30
I have always used 10w30. never had any problems.
It depends on your climate but, in most cases a 5W-30 is used.
