not wanting to start an argument about which one is best but i could do with some pointers to a good quality semi-synth oil for my un-modified 855R
its using castrol magantec at the moment as that was recommended and supplied by the local independent volvo specialist i currently use
the oil will be changed every 4-5K miles
can i mix oils as the car will need a small top-up soon or do i need the same stuff as already in the engine ?
sorry for the dumb-ass questions !! - i've only had non-performance cars before that have used bog-standard oils so have no experience in this area.
