New oil will be thicker for the first 100 miles or so. It should settle down soon.

it is the V6 LLT engine

I got my car back from an oil change today. They put 6 liters of synthetic oil in. I notice that when I accelerate from idle that my oil pressure gauge jumps almost to 500 kpa (the highest reading on the gauge). Once I start going a constant speed (like 40 km/h - 80 km/h) it goes back down to around 250 kpa (the middle reading). If I accelerate again it goes up and then comes back down. If I am on the highway and going 100 km/h - 130 km/h the oil pressure gauge reads about 375 kpa (inbetween middle and top reading).

I had never noticed it doing this before, but I wasn't really looking either.

Is this normal? Shouldn't the oil pressure stay constant for the most part when driving? The oil pressure never drops below around 250 kpa. I don't know if this is from the recent oil change or what? Did they not put enough oil in? (I checked the dip stick and it looks fine) Just looking for some insight for you guys that are more "car know" than I.

Thanks.

My car dose it also. It apears to be normal,( Read post #40 ) or alot of cars have the same problum.

thanks for the link!

Its normal for the gauge to be pegged at certain times.

Only worry about it if it gets low oil pressure.

Its an overhead cam, tight tolerance engine the oil pump is just doing its job, need lots of oil pumped up to those cams.

I disagree. Pegging out is not good. There is such a thing as too much oil pressure. If too much oil is put in, that creates more than normal pressure at high RPMs and that is NOT good. Look under your car, get under there if u can and look for any signs of oil leak or seepage. If you find any, you got your answer.

Whats normal pressure for a V6 then?

When I had my 350Z it would peg out on the oil pressure gauge whenever I accelerated hard. Even under light acceleration the needle would move a little bit; as the car warmed up to operating temperature and while cruising the needle would be constant. So I think it's pretty normal

The only time oil pressure is affected by level is when its low. The higher the level by no means heightens pressure. Viscosity and temp will but not level. High oil level can cause cranksplash in the oil pan from the counterweights hittting the oil deeply, which is bad lol.

you guys worry too much , this is why they dont put oil pressure guages in cars

ACDC1710 · 09-22-2009, 11:20 AM

Pressure is the direct result of flow. The orifice or all the galleries and passage in block, head, crank, cam, etc.. all the stay the same. Your oil pump is a fixed displacement pump which increases flow with engine RPM. The result of the increased flow is an increase of pressure. So oil pressure will fluctuate from low idle to high idle.
