EQUIPMENT MAKE: Nissan
EQUIPMENT MODEL: 2.4L 4-cyl
FUEL TYPE: Gasoline (Unleaded)
OIL USE INTERVAL: 5,300 Miles
OIL TYPE & GRADE: Trop Artic Synthetic 5W/30
LOU: Unfortunately, it appears your Frontier has a small antifreeze problem. We can see the coolant in the potassium and sodium levels. It's affecting the bearings (see lead), so the sooner you can get this fixed, the better chance you stand of saving the engine. The universal averages column shows typical wear from this type of engine after 5200 miles on the oil. That's about the same interval you ran your oil, so lead is somewhat high in comparison. The TBN read 2.6, still active additive left. But run shorter, not longer, oil changes until the antifreeze is fixed. Caution!
