First time writing on this board ! But i`ve been reading for the past year or so.

Can you please explain to me why is it that my -86 Carrera, (930/20 RoW) runs perfect without any knock on european gas with an octane number RON 95, (US 91 i believe) The original handbook clearly states to use 98 (US 93 i believe) ?? We are quite a few of us that has been running this gas for several years now, with tens of thousands kilometers. This without any problem.
I had a top-end job performed last summer due to worn out inlet valve guides/valves at 131 k km. This after driving some 30 k kilometers on 95 and there was no sign of any problems at all that in any way could be caused by using a lower octane rating than that Porsche prescribes. I even DE`s my car 2- 3 times a year.
