Appreciate some input on spark plug reading
They all colour plugs.......
Still wrong. Doubling down won’t make you correct.
If the OP puts color on the plugs it WILL lose power.
Edit: I just got off the phone with VP and the dude said most VP fuel sold down under is blended down there (or close to it) using crude from different sources than we have here.
He said outside of the stupid cost to blend, package and ship fuel from here to Australia you have laws to deal with.
Again, you’ve been told you are wrong but you double down on it.
Anyone can pick up the phone and call VP. Then they’ll know you are talking out of your hat. Again and still.
