Spark Plug Help

Awesome site. Wish I had found it before I bought my AU S1 Forte especially since I paid to have some work done on it (brakes - really wished I had known about the upgrade and exhaust rusted out) but no used crying over spilled milk. I am an expat from the US and I wanted to get something I couldn't get back home so Falcon it was! Anyhow the car has very suspect history as of the last 5 years. Prior to that, it was serviced well.

I just changed the plugs and as it is the first time I've done it ever, I was looking for help interpreting them. Apologies in advance for the ****** pics. First I'm confused since the plugs don't seem to have uniform deposits. They have them on one side... Is that normal? Second, plug number 5 had a wet oily brown coating but not on the top but near the threads. What does that signify? By number 5 I mean the plug is the fifth from the front of the car on the I6 or second from the dash.

Thanks.

G'Day and welcome to the Forums ,, Plugs look as they have worn fairly even could be running a bit rich but they come that way from the factory so I would drop a bottle of injector cleaner through the tank and give it a new set of plugs and see how it goes . How is the fuel economy ?
Have a look HERE the first picture was my sons I6 plugs at 120000 Ks

Forgot to mention - Car has ~104,000 km. It was running nice but after the exhaust change (could be totally unrelated) it would intermittently stall/almost stall on cold starts.I brought it back and they checked it but couldn't get it to stall. I changed the oil, oil filter, air filter, ecu was reset, dropped in some injector cleaner and stalling stopped (coincidence?). now I did the plugs. Can't comment on fuel economy as we haven't driven it much. The car is actually for my girlfriend. I got suckered as a newbie to Oz and took it into the dealer for the tranny flush, rotors and pads x 4 and the exhaust. Mostly because I wanted a clear conscience throwing my non automotive minded gf in the car and also because I called AutoMasters and the cost were similar so I figured dealer would be better. Probably overpaid.. We're in Perth. Any shop recommendations? Any audio shop recommendations? Australia is so bloody expensive.

So just don't worry about the wet light brown oily thread plug?

With those Ks on it I wouldnt be to worried about it as for service in WA some of the WA gang should be able to help out there

Not too worried about the plug, especially if there isn't anything I can do about it...

Any help on the shops or wreckers near Perth? I need some miscellaneous bits like a sun visor and dome light cap, etc..
