looking for some tips on what every one with a zz4 is running for oil pressure at idle and cruize and what weight and brand oil are you using.

 

royal purple 10w30, wix filter, and i run 40psi hot idle, 60+ psi at 1200rpm or more. this is all from the stock gauge btw

 

mine at idle is 16/17psi in drive..and around 40/45 at cruize at 2,000rpms..is that bad? it used to be 20psi or alittle more at idle in drive and between 55/60 at cruize at 2,000rpms..all this started just like that right after i got it out for the summer.

im running valvaline 10w/40 with a AC delco pf1218 filter.

 

it doesn't sound like a problem, i idle at 800rpm because i'm fuel injected and a manual, so with your holly if your idling about 500-650 that could account for the lower oil pressure. when i let the clutch out and my rpm drops to 500 or so, my oil pressure drops as well. keep in mind, we are both (i assume you are) using stock gauges, which are NOT known to be anything close to accurate

 

yeah im at ilde at about 700 or so around there with the mutherthumpr cam it has a mean idle..i am running the pro comp machanical oil pressure gauge and there supposed to be real accurate. so i feel like what its reading is what it is. you think if i switched to a diff brand of oil it would make a difference

 

no, a different brand will have little to no effect, a different weight might though

 

well if its fine like it is i wont worrie about it..just seemed odd that it was running that low all if a sudden. i dont want to go any thicker then 10w40 witch would be 20/50 correct
