*Glenn* 854 Report post Posted October 26, 2011 MHP ?? or is that just a sticker they have used ? I would get the fluid type & grade checked and clarified if I was you. It's dependant on what transmission is in your car. We use either Elf or Genuine oils. This is what I found when I googled Castrol MHP http://www.castrol.com/liveassets/bp_inter...l_MHP_Range.pdf Quote Share this post Link to post Share on other sites
