Say what you will , had a honda with a bad emission sensor , every time
I added Lucas fuel treatment ECL went off until filled up again.
It also keeps the top of my pistons cleaner on my rich running 900hp Willys hot rod...
Looks like it's creeping up into top of roof paint , who thinks a dealer would ever fix it right not me , scrape off loose stuff and put some Woolwax on it, until dealer car wash kid slopes some paint over it.
