Maintenance/Repairs

My 2016 Chevy Suburban has 62,000 miles. At a recent Valvoline oil change, the tech said 1. Replace Fluid in Front Differential every 30K miles. (Never done!)
2.Power Steering fluid change every 30K miles. (Never done!)
3.Replace Fluid in RearDifferential every 30K miles (Never done!)
4. Replace fluid in Automatic Transmission every 45K miles (Never done!)
5.Replace fluid in Radiator every 60 months. (Never done! Haven’t had a radiator leak since the early 1970’s )
6. Replace fluid in transfer case every 45K miles; I did that …he showed me the myriad of tiny flecks of metal trapped on the magnetic plug.

The Chevy Owner’s Manual says Replace Transfer case fluid every 45 K miles, and replace Automatic transmission fluid and filter everly 45K miles. and change engine and passenger air filters.

So, who to believe??? Valvoline or Chevrolet??? YOUR THOUGHTS??
