My clio 1.2 is due an oil change in the next few weeks, now usally i'd throw the same stuff in that i had before but a friend had some castrol 5w30 full syn oil left in his garage when i did my last oil change so we through that in... now at just over 8,500 miles later on i've been looking at oils and fully syn is double the price of fully syn so my question is will it be ok to go bk to semi syn or is it a big no no?
Thanks,
James
