Use the millers 10w40 nanotech high Preformance on the r32 skyline and can fault it engine was def more responsive after moving over from castrol edge sport 10w60. Worth the money I reckon. But use the liqui moly on the 320d daily and can't fault it. Avondhu motor factors in Fermoy stock it at I think approx €25 for 5lt but would prob do ya a deal if ya bought in bulk. Here is there number 02532357. Tell em Kenneth Cassidy said to ring em nd they should look after ya. I'm travelling Fermoy to cork every day could even collect nd meet cha in the city to save ya some hassle
