What color do your plugs look like running nothing but E85? I pulled my BR7 plugs with ~100 miles, and they look slightly darker than white...with a hint of brown here and there. If these plugs came out of a non-corn fuel, I'd immediately say they look lean...I can't post any pics on here to better explain the color of my plugs. If you'd like to see a pic, email me you address and I'll send them that way.
