I have the bf OP... I see 80 - 100 KPA when the car is warm and idling. It's perfectly normal. You should see 400 - 700 KPA under any sort of acceleration.

 

mine does the same thing, defi bf gauge, i just set the warning on the link unit a bit lower and now i have no probs.... good thread... i was having the same concerns

 

Just a follow up:
My last oil change I switched to Red Line 10w40. Due to the higher temp oil I no longer have this problem.

 

I think i just experience that tonight...cause i was driving a bit over the sane rpm for a good period of time...and now my oil pressure gauge is down to 0 and it's flashing?

any ideas as to why it does that...do i also need an oil change cause i'm due for a new one...

 

bump for curiosity on fix

 

Well I use a greddy block that sits between the filter and block and with my defi gauge hooked up I get bout 18ish psi when fully warmed up at idle which is 950rpms and I'm using 10w30 mobile 1. On cold start ups its very high due to cold oil and even when its fully warmed up WOT puts out very high pressure as well,

I think it depends on where you tapped your sensor in for oil pressure, tappin in at different places will give varying results under differenct conditions.
