My quick question:
1997 Nissan Maxima. Summer temps never get over 95f, Winter lows usually single digits for maybe a weeks worth of days.
manual says 10w-30 for 0f and above, 5w-30 for down to -20f.
So.. either one would work. Using a wix filter on the engine with 79k on it. It isn't overly noisy, but if I can quiet it down a bit, I'd like to.
I'm currently using 5w-30 with no detectable usage between 3000 mile OIC. Would 10-30 make any difference , noise-wise or in any other aspect?
thanks
Marc
