I'd like to know what Porsche did that changed the oil, oil filter and spark plug interval requirments from 2005-2007?
They went from 12K on oil and filter, 48K on plugs to 20K, 60K respectively. And then went back to those intervals in 2008? WTF? Different oil, synthetic filter media and Iridium plugs?
My Lexus has Iridium plugs and those don’t get swapped out until 100K. The Hog loves ‘um.
