Are you running a fuel additive/cleaner? You have some chalky deposits on them.

I did put a fuel cleaner in a couple weeks ago if that means anything?

Look normal. Nice and dry anyway. Those deposits can be many things.
Short driving distances, low quality fuel, water/antifreeze in fuel. I don't think the additive would be noticeable in weeks. I could be wrong with the additive, as there are bad ones out there.

There's 1 that does not look like the rest.

Yup, that is what I see. Otherwise they look ok besides the 3rd one from the left. That looks like oil or it could also be the cleaner cleaned that cylinder of a lot of junk.

Would need it in my hands to see if it was oil or just carbon. Hard to tell from the picture.

If you constantly have ran it over time that is what it will do to the plugs.

Thanks,they actually look better in real life,the close-up photo seems to make them look worse.With the link provided my plugs do closely resemble the “Normal Life” plugs.

Hi, I see different colored ceramics here and the gaps look rather large.
