To answer this without doing any testing would not make sense, some diagnosis is needed to find what area of the motor or oil delivery system is causing your problem. Checking the actual oil pressure with a known good gauge is the first test. Second are the valve lifters making a ticking noise? Are there any abnormal noises coming from the motor? Has the oil been changed recently? You can have a bad oil filter, ( there is an internal valve that can fail and cause low oil pressure). You can have excessive clearance in the connecting rod or main bearings. You can have a low flowing oil pump. So, you need to invest in a little diagnosis before we can really help you. Good luck
