Too many variables to make a judgement on plug.
From the color it looks like you have a lean condition but if engine was at extreme load you should have heard some pinging.
Fuel additives nowdays will give a grayish color to the plugs also, should have same co;or at least three threads up, try to get a better angle on picture.
But if you have cracks on porcelain it is too lean.

Could be your brakes, if manual maybe your clutch too....

hi,

i recently serviced my car and asked the mech to take out the spark plug to see the condition of it,

below is the pic:

it looks like its in healthy condition judging by the light gray deposit but the cracks look like i have been experiencing detonation

any help?

Looks like running lean. If overheat will turn yellow.....

well for me it seems to be a little bit fine but if you are not feeling it right than you should probably change it what so ever i mean i would have been changed them if the plugs were lean i mean you could see exactly in the picture right and if there are cracks in the porcelain then why take risk simply just just them if you would like to........
