I just had a 30,000 mile service done on my '03 H6 Outback. I noticed that the shop did not change plugs. My owners manual states that plugs should be replaced at 30K miles. Service manager claims that my car is equipped with "Platinum" plugs that subsiquently do not require changing at this time.

 

I should be grateful I saved some money here, or did the mechanic just get lazy? Any comment?

The following is list of maintenance schedules:

The ones I saw said the the 3.0 and turbocharged cars have a 60000 mile change interval.

Yikes. I guess my dyslexia got me again. Thank you for the reply. I now stand corrected. Question answered.
