Apologies up front for the hijack, but on a related subject, I've just done the longest round in my K series 1.8 Roadsport (Stoneleigh) and should check the oil. The car is new to me and I have no idea what oil has been used previously. Assuming I need to top up, what's my best all-purpose standby and does it matter? Or should I do a change and if so, with what?
All advice gratefully appreciated.
Chris
Reckless with caution.
