Changed my oil out to 0w40 form the castrol 10w60 I used previously for a short while.

When driving a bit hard or even after just one or two pulls to redline I noticed the oil pressure drops to around 15psi at idle. (With the 10w60 it would never drop below 30psi)

Just want to check if 15psi at idle is normal? Or should I switch to a heavier weight? 10w40 perhaps?

Thanks!

 

The service manual calls for a minimum of 14psi at idle, 43 at 2K, and 57 at 6K.

 

I have posted oil pressure specs a dozen times. Look .

 

Its called a search.........................but your fine.
