Mark :

Hello, my name is XXXXX XXXXX I will try help you with this.

Mark :

This engine was not intended to use unleaded fuel but it could be converted to do so.

Mark :

However, there wasn't any way they were marked after modification to let you know.

Mark :

I would advise you to use an additive in the fuel if you are uncertain.

Mark :

It should also be run on 98 RON petrol.

Mark :

You also need to retard the ignition timing a few degrees
