A UOA with more questions than answers... #4711322

Here's the background information. This is a UOA of the bulk oil that my mechanic uses. It is supposedly a 5w-30. It is supposedly from a place called RILCO (Rock Island Lubricants Company).

This was taken after it had been in the crankcase for 1000 miles. There appears to be coolant contamination, which was the reason for the UOA in the first place

Is it just me, or does this oil seem to be quite weak (Calcium, Phosphorus, Zinc) and quite thin (cSt of 7.8)... especially since it was only in use for 1000 miles?

I was under the impression that coolant thickens up oil, not thins it out.

Unless that oil has been very severely diluted by coolant, it looks like terrible stuff.
Might be worth searching the PQIA for that oil company.

Is your coolant overflow showing a loss of coolant?

There are better UOA that show %Oxidation and TBN.

I say its cheap oil.

What was the Potassium PPM ( or % )?

Looks like a 20 grade. That aint no 30 grade.
AAlso ZN ( +phos) at or below API limits of acceptability.

Yes, loss at the overflow.

I was only looking for confirmation of contamination... but ended up being shocked on how badly the test results looked. Wasn't going to pay extra for a TBN for an oil that I don't intend to use in the long term.

That looks like a 20, I think a VOA would be a good move before using it again.

Just some quick searching led me to think that RILCO is just a distributor. This is substandard oil compared to most brands right off of any shelf.

All the concentrations are woefully low. Maybe itís olive oil?


If you want the job done right......do it yourself.

methinks you should send in a sample of new oil.

I wouldn't be surprised if they started with some kind of decent oil, and 'blended' it (read "thinned it out") with something even cheaper to arrive at the product they delivered to your mechanic.

Find a new mechanic or bring your own oil. I am always leery of shops that use name brands that I have never heard of. A reputable shop usually uses known brand oil even if it is in a 55 gallon drum.

For sure and nothing to write Momma about.

Most likely Total Bulk oil.

This.

I'd just find a new mechanic as this one seems oblivious to oil quality and current standards. What else do they scrimp on?
