Idle Oil Pressure

Recommended Posts

Hi, I have looked but its not conclusive from searches.

 

When I start the car cold (after a night or day with no action) the oil pressure at start up goes very high to about 2/3rds of max psi and then slowly comes down. I have no comparitor and forget to ask the lads at the last meet :bang:

 

It does come down after about 1 and 1/2 mins, :snack: I must stress that.

 

Is this typical ladies and gents :thumbs: Basically if its not, I will be getting a new sender unit. :thumbs:

Sounds normal to me mate.

 

Oil is thicker when cold so it resists being pumped around more, hence the higher pressure. Added to that is the fact that the car idles really high (almost 1300rpm if you have the aircon on) at cold start, which will increase the oil pressure further over an 800rpm warm idle.
