I've been looking into oil and honestly have no idea whats going on with the clio. Usually i just buy normal castrol etc for my cars but this is my first 'performance' car. I know you need the right oil for your car obviously, searching online it seems i need 0W-40 or 5W-40 for the clio. My question is: is there any recommended oil for my scenario. Its my daily driver and my only car, i don't do any track days or anything and have also seen lots of different types of oil on the forums but am unsure if there is a difference for owners that race theirs etc, going to be driving a few hundred miles at the weekend about 200-300 motorway mostly and am from northern ireland (in case climate matters). Can anyone help point me in the right direction of oil for my car, and are the really crap and good oils? obviously don't want to be putting any crap in the motor!
