so today i pulled my plugs to change them and when i took them out they had a dark red color.a buddy of mine said its from burning coolant.any one ever heard of that?or have any ideas why plugs would have a reddish color?

 

bump

 

Red residue is from using shitty fuel.

 

ive omly used 100 octane nothing less

 

From where/whom? If the plugs were red, then that is why. Additives used in low quality unleaded leave a red trace.

My plugs look the same way and my car is tuned perfectly.. I also use GT100 race fuel, im wondering if the red color has something to do with Toulene in the gas..

 

Been through a few thousands gallons of Sunoco 100, never had any red coloring.

sickerhatch&gt;You arent mixing av-gas or anything like that are you?

Hmm.. Dont know then.. My car was running great and tuned perfectly.. Maybe it was something to do with the plugs, I was running 2 heat ranges colder NGK v-core plugs..
