Stupid flash blew it out. You can see how the Battery is pink not red.

I got better shots:

Anyone have a clue why it's Red?

Anyone have a clue why it's Red?

It's from the additives used in the gasoline that you pour in your gas tank. Do you buy your gas from a certain gas station or certain company?? Try using another brand gasoline & see if the red goes away. If it doesn't then call your local Air Quality Resources Board and ask them what additive in gasoline causes the tip of your oxygen sensor to turn red. They should be able to answer this question.

could it be the way the motor is running, or do you think that the gas additives are really responsible?

Must have been the seafoam.
