Yea let's keep the thread positive as I would hate if this thread turned into canada-flaming cartagena
I haven't actually looked at the test result yet because the result is being sent back to me. The lab tech (chemist) said that their conclusion (coolant additive, they didn't mention WW) was drawn based on the graphs analysis, so I bet the analysis was a spectroscopy which means there should be other weird chemicals other than ones from the WW.
I should have received the result next week. I will scan and post it here so we can all look at it and see if we can analyze it in more detail
Please note that I occasionally used redline fuel injector cleaner, which has a RED color as well...so this could possibly be the culprint. I don't use this anymore though, as I avoid adding anything to the gas from now on.
