Default Spark plug state check

Hello s2ki,
I drive f20c swapped e46 as daily car.
Previous car was dc5 rsx.
Even if i experienced vtec, f20c was quite differerent from k20a.
One of diffenrent thing is oil consumption
Maybe about 1200km per 1 liter even if i drive over vtec range to test f20c.
There was no oil leak out side of engine.
Engine power was not bad.
Fuel economy was over 13km/L on highway.

When i change spark plug, old plugs were as below.
I could confide only cyl#1 is okay.
But, Cyl#2, 3 and 4 had oily stuff around tip.
How do you think my plug state?
Is it into the normal range?
Thank you in advance.

Relatively normal burn, a little on the rich side. It would be important to include the mileage of the plugs.

Thank you for your answer.
I'm not sure. Maybe mileage is around 20~30k km.

1,3, and 4 look normal, plug #2 is perhaps burning a bit more oil or running more rich. Swap the plugs in different cylinders and check back later down the road and see if the pattern changes. I don't see any big issues with the plug conditions.

Thank you for your advice.
I'll monitor again.
