i pulled a few plugs after racing last weekend and they were orange. i immidiatly thought i blew a head gasket so i pulled a few from the other side and they were the same way. i check the oil it was fine, coolant level was perfect, and the car is not over heating. i was running straight 104 sunnoco so is this the perpetrator?

 

Yeah, it's more than likley the fuel. Mine always do that when running Sunoco 104. They look fine on pump gas.

 

When i use to run 104 it made the plugs look rusty in color but that was normal with that fuel.

 

Sweet!!! thanks guys.

 

it's the additives in the fuel to help bump up the octane rating, it's well known to do that with those lil octane booster bottles also

 

Yeah torco additive will do that also
