I have 4 litres of fully synthetic oil, but my car was filled with semi synthetic oil on it's last service. Can I use this oil to top up my engine, or would I be better to use semi synthetic oil and save this for my next oil change?
 
fully synthetic is a perhaps little OTT for your car engineering wise, but of course you want to spoil here like we all do.

It probably best to shade your descision by getting a pukka diesel formulated oil.

thanks, still not sure if I should use it or not
 
Save your fully synthetic for the next oil change and top up in the meantime with semi-synthetic.

The oil I was given is 5W40 Mega synthetic for Petrol & Diesel, guess that is up to the job. and it was free. :cool:
