Keep in mind that thicker oil doesnt help a engine where temperature is below 50 degrees, it take more time for the oil to reach
all the bearings and lub the mains. Did they put the same grade and weight of oil in the engine? rule: lighter weigtht in winter 10w-30
summer 20w due higher heat. Ive done this to every Nissan and Datsun Ive owner (620,720,200sx 240sx .300zx frontier altimas
99-2000 and 2012, xterras 05 07) and all still run great . One other thing I thought about is the chain tenioners if they are leaking
more than they should it wil also drop the oil pressure when starting, you can also warp the thrust plate in the oil pump thats mounted to to the timing chain cover with heavy oil. There is a plug on the side of the block that will allow you
to hookup a oil pressure tester to it so you can see what pressure your getting at startup after so many rotations of the engine, you might want to check that out. Find out the oil grade first..sky5031
