1994 Toyota Camry V6 with 71,900 miles.

Changed the oil early at 2500 Miles because its the first time the car has seen some driving (the previous owners I bought the vehicle from were not driving it).

Lab said that Copper and Silicon were above the universal average values, but that the high silicon count was probably due to a new seal that I had installed recently (crank seal).

Oil Type unknown, but the lab said that it tested into a "high 5W20." Funny, since the oil cap on the car says "Use 5W30."

looks like pennzoil 5w20 conventional.

Could be 5W30; maybe the engine just shears oil.

A Toyota engine from the years that made the brand what it is today. Beautiful. Considering the miles and the year, 2500 miles on the oil could be 2-3 years maybe more sitting in the sump exposed to environmental variables (air, heating, cooling, moisture, etc) Then suddenly being used the additives were gone, oil sheared right down.

 

[silversapphire]

The previous owners changed the oil a few months ago at *shudders* Jiffy Lube. I ran the car for 2.5k mi on that oil. Is it possible for 5w30 coventional oil to be sheared down to 5w20 in a few months and 2.5k miles?

The oil prior to that change was probably 1 or 2 years old from just sitting around.

 

[LeakySeals]

Then it had bulk Pennzoil 5w30 dino in it. Should not have sheared down that fast. Its possible Jiffy Lube was out of 5w30 and slapped a 5w20 in. Or made a mistake. Would assume they would not confuse a Toyota that old with a newer Toyota requiring a thinner oil. Following the UOA's posted on here its also possible the results of the sample is off/listed wrong. There are several threads on here where people had that happen and requested a resample.
