I've noticed that my oil pressure drops significantly when I'm idling; is this normal?

 

MY 04 Tundra also had very low oil pressure at idle(from the factory). IIRC, the owners manual says that it is normal.

 

grogg,

i installed an aftermarket oil pressure gauge. this is what happens on mine:

- at start up, pressure is around 75psi

- a few minutes of driving street, its about 50psi

- after about 10-20 mins, its about 25psi

bob

 

Its normal for the oil pressure to vary at different rpms.
Cap'n

 

Toyota has a bulliten on the low oil pressure problem with tundras, we are replacing the oil sending unit. Hope this helps.

 

Thanks for the info. Where can I find this bulletin?
