i changed the oil to 0w40 fully synthetic from mobile 1 .. its the only one i could find.. looks fine on idle its exactly in the middle and goes up as the rpm rises... i havent checked it exactly using Hp tuners.. when i start it when its cold.. the pressure rises *more than middle* after 5-10 minutes it goes back to middle is that ok?

 

in your climate it would be best to run 15w-40. you will probably never see sub 40 degree weather over there.

 

That sounds normal to me
