I'm about to change my 93CSE fpt oil for the first time since purchasing the car. Is there any way of telling what type of oil is already in there?
I will be using a synthetic but if it was a mineral oil previously I'm told there's a chance the synthetic may cause any coking from mineral oils to break up and move. The only information I can see is that at it's last service it had 4.5 litres of "F5000" as the service part number. Can you smell/feel/see if the existing oil is mineral? It seems in good condition, not too dirty or burnt with good viscosity.
