When my engine is warm and idling the oil pressure is rediculously low (ie below the lowest mark in the gauge). When the engine is cold and when it is under load or just being revved the pressure is good (ie near the middle of the gauge). I've checked the level of the oil on numerous occasions and it is right in the good range on the dipstick. Should I be concerned about this?

nope its a lot less @ idle because it doesnt need to have mroe pressure

Toyota manual says minimum pressure at idle is 4psi if I remember correctly. What weight oil are you using? Going a little thicker wouldnt hurt.

I use 5w30 in the winter, but when I changed it last week I put in 10w30 as it's starting to get warmer.
