Could be the oil. Mine went up aftere better filter and mostly all 5w-20. In it .Hello All,
Does anyone know exactly where the oil pressure is measured in a 2014 5.7 Hemi?
I just bought the truck and changed the oil and filter (5W-20 full synthetic and a FRAM XG2 synthetic filter). The oil pressure immediately went up about 4.5 lbs after the oil/filter change. My thinking is that if the oil pressure is measured before the filter, then my new filter resists oil flowing through it more than the old one, and I might be getting less oil into the galleries. However, if the pressure is measured after the filter, then the new filter is probably passing more oil into the oil galleries.
Thanks in advance for your advice,
Terry
Micron or millimeter sized rocks?Oil pressure is measured after the filter. I think your Fram filter has a rep of letting rocks through.
