3 year 21K mile, engine oil abuse, UOA worthy or waste of money?

What are you even doing on a site like this, if a UOA of the OP's oil doesn't at least interest you a little?

I'd be curious to see it. Maybe a waste of money but it's still interesting.

So maybe for now?

I work at a supplier for auto industry and we are wiped out too but will probably come back sooner than airlines, tourism, restarsunts etc...I am much more worried about poverty than virus

and the filter

I usually see this carbon sand stuff in the filter but usually just a few bits of it, this is ugly.

nothing to see in the filter itself, Its a depth filtering Toyota filter that cannot be easily cut apart.

Agree! couple of short oil changes and she'll be good to go.

Part of me wants to UOA it to find out what happened, this will be a serious edge case and might be interesting, part of me thinks it a waste of money to find out what I already know, that this was a horrible engine/oil abuse.

Thoughts?





Get that uoa bud.

I'm not an expert but doesn't that oil filter say the uoa won't be any better? It looks nasty.
I don't do uoa, but I look at others. This one I would be interested to see

As we all know, a UOA is the only way to know. What you might be paying for is badly skewed info.
Or it might just be another routine oil analysis.
Got budget?


According to Jim Fitch (pretty much THE authority outside of our super knowledgeable guys) a small amount of oxidized bad oil in a system can remove a very high degree of the new oils life, and by definition a sump change is a " short volume oil change"- hence the double change using low cost but rated oil and filter as a cleaner.

OP, Certainly dirty, but Ive seen much worse, if you can see how much is packed in the pleats it will give you some more info on how full the filter was.

For low cost fun drag a magnet though that goop...
