Ok cool, i normally order from opie and the last oil was only £8 more for 5L(so £16). Always been a little dubious with supermarket oils(granted as long as meet specs should be fine). I will check the oils out next time im at a tesco or asda, see whats what. Next oil change which is only 2k off, will try some 229.5. I will still change frequent though as its paper oil filter which can break down in the longer duration, the newer oil can last. I am a little overkill with maintenance though, i admit that. Thanks again gaz.
