Plug condition after 55K miles
Thanks to TxStig for the coil tool, I noticed lately a lot of us are changing our spark plugs. I have not seen anyone post photos of their plugs and mileage. I changed mine a couple of weeks ago. I ran close to 55K miles on these plugs and with 93 octane. This is not a debate about when you should change your plugs. My plugs look as I would expect a set of 55K mile plugs would look like. Mild fowling in #1 and #2, slightly rich (factory is always conservative with AF ratios) and no excessive signs of detrimental wear. My engine uses about a liter of oil between 15K mile oil changes. Please post photos of your plugs and mileage.
