I went just now and they had 5-30 synthetic for £15.65 for 5l in a dark green container but not fully synthetic.
They had one litre top ups with 5-30 fully synthetic which was grey.
What the difference between synthetic and fully synthetic?
I had a look on the website but it isnt really listed the same as what they stocked in store.

They had part synthetic which is semi, but i am slightly confused with synthetic / fully synthetic.
Martk_88 What colour is the bottle of oil and did it say synthetic or fully sythetic?
I have just found this on another forum.

From reading this i am guessing that it is just semi synthetic oil dunno.. , which seems fine but i presume you can not mix with fully synthetic dunno..
