Wow, thank you all for the very kind responses...and what detailed answers too!

Ivanerrol - I couldn't find the EZL octane dial But major thanks for the detailed info on my car. I knew it was possible but as I said, google failed me this time!

I did find the Catalytic converter so thank you for the pics LUVMBDiesels as I would never have known what to look for otherwise!

So I guess it's safe to say that I'm ok to carry on filling with normal 95 unleaded petrol.

Northern Cyprus is indeed beautiful and although I've only been here two years, it truely feels like home. Oh and for all you 190E lovers - there's a ton of them here, all in pretty good condition too! The funny thing is that here they cost probably 5 times as much if not more than if you were to buy one in the UK (massive import taxes here!) There's a whole load of other classic cars here too (lots of Mercs ), most still running nicely, and some abandoned at the side of the road, so if you're looking for a classic-car-spotting-holiday then North Cyprus is the place!

Anyway, thanks again for the help...no doubt I'll be back with more odd queries
