Since re-locating my oil pressure sender via an 18inch braided hose, my oil pressure never reads above 5 bar - no matter what! It idles cold at 5 psi, hot idle is 2 - 2.6 bar and normal driving its about 4-5 bar. Even nailing it never sees anything over 5 bar.
Is this related to the 18 inch pipe or the 10w40 FS oil? With the 5w30, it would show slightly higher figures.
Is this related to the oil, the pipe or maybe an engine problem?
