Now that's funny. You're the guy with the factory qualifications, and you started this, so it is actually up to you to back up your original statement. However I will be away for a couple of weeks or so - probably spending them queueing in gas stations across the south west of the US, so I'll leave you to decide whether to justify it to the rest of the group.
Suffice it to say that I have had no problems with the petrol engine in any Peugeot that I have owned in the last 45 years, from 403 to 806 via 104,
204, 205(several types),304, 305(ditto), 306XT, 404, 405GTX and 504. That is the basis of my disagreement with your rather sweeping generalisation.Ron Robinson
