Hi Norm:
Yes Sir. Valvoline in both the car and the truck now and the lifter tick I was getting on the cold morning start ups in the truck is gone.I thought all along it was just that the truck was getting old.No more mobile one for me and I have been a big user for over 20 years.Truck oil with 1000 miles looked like it was in there for years and did stink like you said.Brother just switched his honda and his 2005 gm truck also last week.Thanks for letting us know
