G’day All,
With reference to MF’s photo above of the oil tin, what is a 20/20w oil? Is it a multigrade (in which case what does it do ) or is this just a marketing jockeys way of selling straight weight 20w oil so that it sounds all ‘tech’ and impressive to the average punter???
Nope, not a multigrade; just an odd way of stating a monograde rating!
