Jeeps Oil Pressure
With the old engine, the oil pressure stayed and was maintained between 45-60 psi and with this new engine, at first it was also the same. After time it began to get lower around 30 psi at idle using 10w-30 (recomended) and would not go above 40psi while driving on the highway. I thought maybe it was due to the cold weather and changed to 5w-30 which is also recomended as an alternative for cold weather. After doing so the oil pressure went back to what I saw as normal operating pressure for my jeep which was around 45-60 psi, Recently however, after about 800 miles with the 5w-30 the oil pressure peaked the guage at 80 psi is this cause for concern and what might this mean, other than viscosities of the oils? :?:
My opinion you're doing okay-perhaps the idiot gauge is acting up-out of calibration won't hurt to do an engine flush.
Anything less than 15lbs @ idle calls for concern-remember oil pressure will increase with rpm-the oil pump is spinning faster
