2012 Mustang 3.7L V6 - Unknown Oil, 6,857 miles

[RDY4WAR]

This is the first sample taken from my wife's 2012 Mustang that we bought back in February. It has >136k miles currently with >6,800 miles on the oil.

We purchased it from a dealership who changed the oil before we bought it so I have no idea what oil they used. It held up well though, whatever it is. I replaced this oil with High Performance Lubricants HDEO 5w-20 which I posted a VOA of on here a few days ago.

Seems unlikely to me that a dealer (assuming this was an OEM dealer, not a dirtbag used car shop) would put in anything that wouldn't meet the spec.

We bought it from a big Chevy dealer. They've been good to us in the past so I trust them.

Excellent uoa and looks like a great oil! Lots of moly. You should call their service dept and ask what oil they use.

Used Car dealer? Is this light duty diesel oil? Doubt this add-pack meets SN Plus. But plenty-good for OPs nine year-old vehicle.

I called the service department at the dealership where I bought the car. They pulled up the service record for it. The oil is Pennzoil Syn-Blend 5w-20.

Being a syn-blend, I'm impressed with how good it looks at 6,800 miles. That would be a good 7,500 mile oil. This is a lightly driven vehicle also. My wife never takes it over 2500 rpm and usually cruises at 1200-1500 rpm.

With the moly being at 200 ppm, I suspect that's dinuclear MoDTC.

Just follow the IOLM. That 3.7 would.have been exceediny happy with 10,000 mi / 1 year changes with that oil.

5W-20 HDEO?

Must be something new. My newest HD Engines recommend 10W-30 and allow 5W-30 (Synthetic).
