This is the latest sample from my Dodge Caliber. I wrote "nothing out of the ordinary" on my note to Blackstone because this interval was pretty much just that. Lots of highway mileage, took a trip to Salt Lake City & back, and my commute to work is 15-20 miles one way. Plenty of spirited trips to redline, so surprised to see the low wear. Oil filter was a Mann (purolator knockoff).
Manufacturer recommends 0w-40 synthetic, but so far I've found that 30 weight oils get better gas mileage and offer good protection. I switched to a 40 weight for summer, Valvoline Durablend Semi-Syn 10w-40 this time around and a Fram Ultra filter.
The previous oils shown on the UOA are from first to last:
Motorcraft CJ-4 10w30 "Super Duty" oil
Quaker State "Torque Power" 10w-30 Synthetic
Shell Rotella T5 Semi-Syn 10w-30
Havoline 5w-30 Deposit Shield Synthetic (current UOA)
