Quite perfect. Probably using lead additive?

Look pretty good to me.
My plugs have that reddish colour since swapping to millers vspe, didn't get it using Castrol valvemaster plus.

Thanks for the replies, no just using Shell v power as I've had inserts fitted to the valve seats.

Same fuel I run in mine, maybe the fuel makeup has changed because I didn't used to get that red tint on the plugs.
I only noticed sometime after changing brands on the unleaded / octane booster additive.

This is a good chart.  50 miles isn’t much distance to judge it on though.
