Low oil to No oil pressure at idle?

I have low to no oil pressure at idle. Give it the slightest gas an up to 40 she goes. Upwards of 80 WOT.. What should I do..

Re: Low oil to No oil pressure at idle?

when you say you have no oil pressure, do you mean ZERO or a small amount? Is this with the engine hot or cold? There could be many things wrong.. but I would suspect gauge and sender first.. 40-80 psi at speed is good pressure - and as little as 10-15 psi at idle is good as well, some gauges just are lazy on the low end... of course I could start the doom and gloom that notably happens in some of these threads, and tell you your bearings are going bad, or the oil pump is plugged or failing etc etc.. But to be honest.. I think you are fine..

I have low to no oil pressure at idle. . . . What should I do..

Fix it.

Start with the easy stuff first . . . maybe the sender or gauge. If that is not the problem, then things get pricey, as the engine may need a new oil pump or the lines cleaned out, etc.

How old is the engine?

replace sender with mechanical gauge and test.

what weight of oil are you using?
