Hi,
My Tacoma calls for 80W-90 or 90W in the differential. I've tried 75W-90 synthetic and like using it but the differential seems to have a slight 'whine'. Maybe it's just my imagination but when I go back to a 80W-90 it just seems a little quieter on real hot days.
Can I mix 75W-90 Mobile1 with 75W-140 to thicken it up a bid at the high end? I was thinking 1.5 qt of each to make up the needed 3 qts.
Thanks.
ps. I'd like to find a readily available 80W-90 synthetic.
