Well, this is my first UOA. This oil has since been changed out.
The vehicle was my 1996 Chevy Caprice Classic with the LT1 motor.
I don't know the oil used, but I'll try to find out from the seller tomorrow. Whatever Vandevere Olds/Pontiac/Buick of Akron, Ohio puts in used cars that get traded in, presumably a 5W30.
The new oil is 1 Qt of Rislone and the remainder filled with Supertech dino 5W30. I intend on going to German Castrol when my new oil hits 1,000 miles, unless I get concerned about radiator fluid contamination.
Mileage on Oil: 4,120

Make-Up: It got maybe 3/4 of a quart below full line before oil change time, but no top-off was done.

Comments from Blackstone:
This was a 5W30 and since we don't know the type, we can't be positive of the source of the sodium. It is common to anti-freeze, and while this level is not harmful for the engine, it is something to monitor closely. It could be from other sources. We should be able to tell you more in the next sample. You mentioned an air intake system problem. The silicon probably shows abrasive dirt that was slipping by the filter. It hasn't hurt much but we are glad you corrected it. Wear was normal, compare to universal averages. Check back due to sodium.

Usage is mostly 13 mile 11 of these highway, 20 minute commutes to my job, interspersed with weekly 50-minute jaunts to family members. I put the hammer down occasionally, but only when the car is thoroughly warmed up and usually only for a couple of seconds.
At about the 900 mile point for this oil the vehicle was in an accident that cracked the air intake. The body shop replaced the air intake subsequently, but the vehicle was operated briefly with the intake cracked.
Here's the question that's bugging me:
Can you think of any oil that a domestic new car dealer would put in a vehicle on his used car lot that has sodium levels near 21?
I went digging through the VOA section, and I think I saw one Euro racing oil with a sodium of 650, and a couple of others including Redline 5W30 that have sodium levels close to 21, but all of these share the common denominator of being pretty darned expensive.
That pretty much means a dealer won't put them in a used car that will be sold off shortly.
So, once again, is there any bulk oil or cheap oil out there with a Sodium level near 21?
