High Oil Pressure? - ZR-1 Net Registry Forums

RiceEatingZR1 · 10-11-2007

what is the norm? for oil pressure? I noticed that mine seemed a little high when I was driving around on Tues. however after I was driving for about 30 mins or so the pressure dropped down. Just wonder what the normal pressure should be

where is the needle on the gauge? mine when cold is right on the high mark .when the oil temp levels @ the last o of the 100 the gauge readsabout 3/4 on the gauge. this is true for all 3 of my zr1s . hope this helps.

Mine does exactly the same thing. I was a little worried about the 15w-50, but it seems to be fine once it warms up.

why do you use 15-50 .does your car eat alot of oil ? you might want to ck on line on some tests on the power loss when using heavier weight oil. i believe it costs almost 10 rwhp compared to 10 -30. mobil one also has come out with 10-40 syn which might be a better comprimize. hope this helps

Shaun,

I use 10-30 Castrol GTX. When motor is cold pressure runs at about 75-80psi then drops to 60 once oilo warms up.

BTW, you planning on coming the 20th at Byron. Should have about 4-6 ZRs there if weather holds.

Jon, we live in Las Vegas....I've seen my temps go to 230 - water. I wanted something a little more for the heat. Now, I could drop down for the winter....

Mine is the same though it stays slightly higher now since I put the PurePower oil filter on it - which is expected because it filters better and adds a little more 'restriction'.

There is a load of information on the pure power site (www.gopurepower.com). It's basically a washable re-usable oil filter with a lifetime warranty.

Expensive, but I thought my Z deserved the best and it looked like it was going to be a pain getting oil filters up here anyway.

Vette magazine also did a write up on them, last year I think, with positive results (http://www.vetteweb.com/tech/vet_050...st_oil_filter/ ).

They didn't list a specific ZR-1 filter last time I looked, but I emailed them and they came back with the right specs, I've had no problems at all with mine and it's comforting knowing that I'm getting good filtration. It's also amazing how much rubbish that it pulls out on the first couple of 'changes'.
