Federated Auto Parts has changed their supplier for their house branded Federated oil filters from Hastings to a Chinese company. The Chinese filters look good, but the filter for the Renegade 2.4 replaces 3 Hastings filters. The 3 Hastings filters were close to the same size, but the bypass pressure valves are 8 psi, 14 psi, and 20 psi. I can't find the specs on the Chinese oil filter, and I don't know the specs for the Original oil filter. My question is; Does anyone know what the oil pressure is when the 2.4 is cold and hot and does this really matter? If it doesn't matter why would Hastings make 3 similar filters with 3 different bypass pressures?
