you first need to fit a gauge to the engine and see what the actal pressure is through the rev range ..renault should be able to give you the figures.....though i am not familiar with renaults ,change oil filter ,using a genuine oe part ..check pressure relief valve , and if possible ,remove oil pump and see if you can find anyone who can test it
