Also I accidentally gave myself a heart attack a week after I bought it!
I’ve driven nothing but diesels for the last 17.5 years, so the switch to e10 completely passed me by. When I bought my gs300 I filled it up at the nearest garage… almost certainly with e10. Which I later discovered the 3rd gen gs300’s can’t use.
About a week later lots of Check VSC warning lights came on, which obviously caused me to fret. Then a couple of weeks later, after having topped up a few times with e5 and gradually diluted the e10, after I filled the tank up the Check VSC warning lights disappeared for a while before coming back on. I topped up again last week… and the Check VSC warning lights vanished, never to return.
I can’t prove it, by I’m 99% certain that they were caused the e10 fuel. It can’t be a coincidence, surely? I know that the Check VSC warning lights can be caused by a faulty O2 sensor or an I’ll fitting fuel cap.
