Stick with PU or Synpower and you will find it runs great
PU is what is going in there on the next change and I was thinking a 5w20/10w30 50/50 mix, but might just go 10w30 since the startup clatter goes away with 10w30.
Sonataman,
Tell us what filter(s) you are using ?
And also, have you been using different filters with the different grades of oil ? i.e., filter "X" w/5W20 & filter "Y" w/ 10W30 ?
Of our 4 vehicles, I have noticed much of what you are describing in only 1 of our cars and it has to do more with the filter than the oil. '04 Altima 2.5L/Puro Classic works well.
The Nissan OE filter, Super Tech, FRAM & (PureOne believe it or not)all caused me startup rattle, winter/summer, didn't matter.
Puro Classic and NAPA ProSelect did not cause startup rattle! So, I've been sticking with the Puro Classic #14610(no rattle, available everywhere, price)
You my find at some point that even the 10W30 will cause you some noise. Then I'd be inclined to blame the filters anti-drainback valve(ADBV). You will also find the oil/filter combo that works best for you and personaly, I'd stick with it. You may already have!
