Has anyone switched their oil over to 5W30. At 140k the old girl is burning some oil. I'm thing the 5w30 might slow that down a bit along with being more resistant to the summer heat. Thoughts??
I switched my 07 navigator to 5w 30. It had 33,000 miles on when I did it. I looked up the 20 vs 30 viscosoty at 200F and they were very close. So that was good enough for me.
