Mixing Synthetic Oils

Can I mix Mobil 1 Syn with other synthetics. Also, I have a "oil burner" 1989 300E with about 200,000 miles + (don'tknow the mileage exact because it stopped at 91k). I don't want to completely move over to synthetics so I stick with Chevron 20w50 but I was wondering if I could add like a bottle of Mobil 1 Synthetic every 3000 miles

1997 E320
1999 S420
1989 300E
1996 SL600
