5W20 for ALL 4.7L?
I'm running 5W-30. I've got a lot of miles on this Dakota and I get that ubiquitous start-up clatter when the truck's been sitting. I checked the oil pressure with a gauge some months ago (sender had failed) and it was good.
I know Dodge now specs 5W-20 for their newer vehicles with 4.7L, but I've also heard talk that this is now the Dodge recommended viscosity for all 4.7L, to include the early versions. Also saw some state that they took their old truck in for an oil change and the dealer puts in 5W20. Still, I can’t find oil charts online that state this and the Dodge sites only go as far back as a 2004 Durango.
Well, 2016 is upon us and we know oil, especially good synthetics have come a long way. I’ve seen torture tests where 5W20 oil film holds up as well or better than 30 weight.How many of you are running 5W20 in your older 4.7L? Mostly, my concern is with the oil pressure. Have you checked your oil pressure (aside from the dummy gauge) since running it?

5w20 is all my dealer uses now. It is better in cold weather start ups, especially OHC engines like the 4.7L. It flows a bit better when cold and still lubes well when hot. It should be fine in your truck.
