I pulled my plugs and they were fine.
I switched plugs when I was trying to figure out what was going on after the reflash from the recall. If there was gas run without the booster and the plug was pulled the slight orange was pretty much gone.
I used VP Octanium in my car. My car sees the track more than the street so probably more often run with the booster than not.
Last year when the dealer tore my motor apart I looked at the heads. I did not have the issues that
@Speedy! was referring to.
I used that stuff for over 2 years.
So like the, I used E85 for a couple of years with no issues, comment.
I can say the same for the Octane Booster.
