oil pressure is revs dependant...

mies is 75 psi when cold start and then varies fron 30 psi to about 70 depending on revs..

mines does go lower than 2 bar at idle when oil is very warm.

lowest is about 23 psi when oil about 100 deg.

as long as enginee sounds ok and the pressure isnt 15 psi or something silly it should be cool.

Mobil 1 Motorsport 15w50 or Silkolene PRO R 15w-50 is your best bet mate. Saving a few quid on cheaper oil is just not worth it
