stp oil additive

[flybymike]

I have accidentally filled the oil sump of my diesel engined vehicle with stp oil additive for petrol engines. Will this harm the engine in any way?

Sorry, I should have made clear that I have only added a single bottle of stp oil additive via the oil filler cap, not that I have filled the entire sump with the stuff!

My query was whether the fact that I had used the additive intended for petrol engines rather than the correct additive for Diesel engines would harm the Diesel engine in any way?
