RE: 10W40 may be Problem Oil
By RJP - 04/22/2001 10:21:41 PM; IP 205.188.200.183
I have switched most of my engines FEs and 385s except boat engines to 10w-30 from 20w-50 because of this drain-back issue. I first discovered this was a problem on my 66 Galaxie/428 that used a qt. every 700-800 mi with 20-50, switched to 10-30 and consumption went to 1 qt. every 1200-1300, almost double and with only about 5 lbs loss of oil pressure.
This thread, so far...
