Ok guys i need a vote here a friend of mine takes his 1995 Cadillac Seville with the 4.6 northstar to my shop for service..
The engine calls for 10w30 and that is what i always use (10w30 high mileage Pennzoil)
He wants me to put 5w30 HM in there for the winter and asked me what i thought about it.. I told him what i thought and then said i would ask everyone on my favorite forum.. I also use either a/c delco or purolator filters for him this car is babied most of the time and he always lets it warm up at least 5 minutes in the winter, car has 175,000 miles and runs like new
