and my engine is quieter than it has been in a long time

X/ Isuzu Ascender has a tighter engine compartment to work on

Engine holds 40 psi hot idle and raises to 65 psi at rpm using mobile 1 5w-30.Definitely recommend Melling pumps

Like any product from melling I rebuild the engine around 6 months ago and oil pressure strong like the first day... and it is a work truck... if you know cars close you know how quality it is!!!...

after engine was warm it carried decent oil pressure but the new OIL PUMP boosted pressure about 20 pounds to 55 psi
