CSR 260 oil pressure to high??

[Tictac07]

Had my new toy for a week now and decided to drop the oil and replace the filter. Original oil pressure 2 bar at idle hot, 4 - 5 bar above idle hot. Believe original oil to be Caterhams own. Now running Mobil 1 15/50 as recommended by Minister. New UFI filter replaced previous UFI filter. Oil pressure cold at idle is now around 3.5 - 4 bar, hot at idle just over 2 bar. So I guess thats the stiffer oil when cold? I take it easy until oil temp is up to 70+. Oil pressure when up to this temp and pressing on is nudging 7.5 bar which is quite a bit more than I seemed to get on Caterhams brew ,Is this to high?? I'm worried about blowing a seal somewhere??? What pressure is to much on these engines. (Engines done about 1200 miles)

Mobil 1 seems better at maintaining pressure when up to temp but is this to high?????

Oh, and there pretty nippy are they not! What a car!!
