P.S. good thread here thanks
That is the stuff that turns everything orange. Still have half a bottle. Not my cup of tea. A lot of the high end octane boosters seem to do it. Common ingredient? I have been using the 104+, basically a glorified fuel system cleaner but has been working for me. Buying it by the case.
