Pulled the plugs on the 90 20v today (7a eng code) just to have a look at the condition been in now for 20k miles. The colour was an orange colour almost like rust, never seen this before just wondered if anyone out there has any kind of explanation. I do use an ocatane booster in the fuel but can't believe it's that. Car runs fine.
