New oil filter brought oil pressure way up!

[trainville]

I recently changed the oil in my '03 and replaced the Mopar filter with the new Mopar performance one (the one with Viper logo on it). Now the oil pressure is almost always around 75-80 psi. Is that too high? I know oil pressure is good and all.....but.....does too HIGH an oil pressure put unnecessary strain on the engine?

It seems my oil pressure was about 65 psi before the new filter. I read on the forums that the new oil filter increases oil pressure. Should I go back to using the standard oil filters or enjoy the high pressure???

And before anyone asks, I am using the same weight of synthetic oil before and after the new filter.

either one will do.the new one wont hurt

You can't have too high oil pressure.

Thanks Chuck - I am relieved to hear that.

Noticed the same with I changed the oil on my '04. You're not alone!

I wonder if this helps any with the oil starvation these cars have??

I haven't installed the new Viper filter on my GEN II car yet, bought a few from Chuck so next oil change I will. Wonder if has same effect on GEN II cars?

if you are referring to cavitation at the pan, no.

ok i guess im just confused with the whole oil pressure problem our cars have.what im getting is that the rod bearings might suffer if they done get eneough oil to them.But with the new oil pan or upgraded swing arm it fixes this.this is also just if you track your car to right?

"Maybe" a bit......the idle pressure is up a bit too, THAT helps a bit, for only about 5-10 critical seconds!

The arm swings with centrifugal forces, left and right...

but if u drag race every now and then you should be fine bec your not going left or right..

Someone will have to say where the oil pressure sending unit in Gen 3/4 is....

If the pressure is measured after the filter, then the filter is less restrictive and the higher pressure indicates the potential for higher oil flow throughout the engine. Good.

If the pressure is measured before the filter, then the filter is more restrictive and is a "plug." If the oil can't go anywhere, it will read higher pressure, but less flow throughout the engine. Bad.

In my Gen 1 I have drilled extra inlet holes in a filter (the smaller ones around the large center are the inlet, stuff is trapped on the outside of the pleated filter media, and travels back into the engine via the large center hole). This resulted in increased oil pressure ~5 lbs on the OEM gauge. So my first reaction is that "normal" oil filters are restrictions...

Assuming you use the same grad/weight/viscosity oil the reason the oil pressure is higher is because new oil is not sheared down, that is the old oil becomes less viscous with use.....

Oil pressure is taken AFTER the filter & cooler, back at the block.

Dan,

how about gen 1/2 ?

 

[01sapphirebob]

I have one on my '01 RT/10 and noticed the oil pressure was up a little bit.

I haven't installed the new Viper filter on my GEN II car yet, bought a few from Chuck so next oil change I will. Wonder if has same effect on GEN II cars?

Same thing, after the oil filter.
