I'd still move forward with changing your plugs. I'm not sure how old mine were but i was getting 10-15% fuel bure difference. Since the change fuel burn rate has been the exact same.
It's a relatively easy job. The only thing i suggest is to remove the inboard exhaust tubes to allow you access. It was a 3 beer job.
Use these tools to make your life much easier:
Boot puller

Wobble sparkplug wrench

And I changed to these much cheaper champion plugs from the AC Delco's
