a steel 20 litre drum - that's pretty rare these days...must be pretty old. Toss the oil and make it into a rubbish bin.

Don't think its rare here. Seems to be standard farmer issue, though I don't know where they buy them.

Maybe here

TBN should be 8.9 apparently. Quite high.

Yes, I have wondered this myself.

How do you mean "annoyed"?


As in, I paid for it, in the past, but now it's old, and I don't really want to use it. But I won't throw it out either.

Oil from the river would go directly into the used oil drum for burning.

Oil change on a big truck is typically two of those cans.


I'd love to know of a truck engine that holds 110 gallons of oil...

Oil doesn't get "old" on non-geological timescales. The spec might no longer be appropriate for new kit, but otherwise, you're getting annoyed about nothing.

.

You're thinking of 55 gallon drums. I'd have trouble moving one of those on a bicycle even if it was only 2/3 full

Could be, given the dirt, though from tilting the can, the content looks cleanish.


Be careful about that--if that barrel does contain used oil and sat for a couple months before you found it, the soot and other particulates will have settled out to a large degree. So you may very well have seen "cleanish" oil, even if it was used. If that's indeed the case, then the stuff towards the bottom will be black sludge.



This is obviously worth checking, but I'd be surprised if that were typical.

I kept a bottle of the residual oil from my second very short OCI sump removal on the current car (which had a lot of metal in the oil). It was, considering the oil only had a few hundred miles on it, very dark, but it never seemed to clear at all, and I'd be surprised if diesel soot was heavier.

Not sure what testing I could do. If the same stuff is available in small quantities I could get some comparative index of viscosity with a bought bottle.

Going beyond that, say to TBN, is likely to be too much trouble.

UOA as a consumer-level service is unlikely to be available here. Maybe commercially but its unlikely to be worth the expense.
Well-shake it up real well & pour 8 oz./240 ml or so into a glass, let it sit a couple days-see if it separates into water & oil or if anything falls out. I wouldn’t hesitate to use it in a beater petrol engine, as long as it didn’t burn a lot of oil (with a catalytic converter installed).

As long as it carries the proper Sx API rating, i am using myself a SL / CI-4 rated 15W-40 HDEO for the first time in my 1988 Ford Escort and i like it, very low oil consumption ( less than when using a 20W-50 PCMO ) and it seems to be cleaning up deposits.


I have been pondering this for quite some time.

When I started turning wrenches on OTR trucks in the 60's we never thought of puting diesel oil in a petrol engine. Diesel oils were formulated to combat soot and high sulfer from the fuel and PCM oils were formulated to combat carbon deposits (sludge) and acids from unburned petrol.

I guess times have changed with the new mixed fleet oils and I have to get my head wrapped around it!

I'm aware of that...but the idea of using random cheap oil you found in the river couldn't be more absurd. Maybe if it was a full sealed container of some good synthetic...but unknown cheap china brand half contaminated? You couldn't pay me to use that in the lawnmower!

You're aware of that but...er....you want to talk about something else?

OK

I don't yet know if its contaminated. If there's any sign of contamination I won't use it. I already said that.

I don't use synthetic oil (whatever it is, opinions vary) anyway. I wouldn't use it if it was the same price, but if you paid me to use it, and it wasn't too recent and skinny a spec, I would, though I don't have a lawnmower so I'd have to reluctantly put it in the car.

At the moment (for the last 4 years IIRC) I've got a mix of CPC SAE 40 and Mobil Delvac MX 15/40 in the car. Before that straight Mobil Delvac MX 15/40. Both mineral oils. Can't get the Delvac any longer.

CPC is an unknown brand to you because you're an American. It is not an unknown brand to me.

And its not cheap oil. Its free oil.

You're missing the point. As cheap as oil is, it's not worth my time to clean off a dusty bottle, let alone wonder if it's still OK inside.

Clearly you have no concern for your engine's well being, so by all means, dump whatever grease you can find in there. What are you saving, $10 or less?

Dunno exactly. There might be about 14 litres, which would be about $45.

Thats one oil change in my truck. If you called and told me you wanted to give me the entire can new off the shelf I wouldn't touch it.

Seriously...its trash, even when it was still sealed. Dump it with the used oil.

Yeh. I know that. Right now car has Mobil Delvac MX 15W/40 in it which "meets or exceeds" SJ though I believe it isn't actually API certified.

This stuff doesn't appear to have an S rating (though I believe it is actually API certified for its C-rating)

That, IIRC, was my original question. What are the issues with C-only oils?

Delvac MX 15W-40 does meet ASPI SJ/SL according to all the places i have checked, at the moment i am using Shell Rimula R4X but i want to try Mobil Delvac MX next.

So you see a lot of problems cause by China Petroleum Corporation oils in...er...North Carolina?

Yeh, I said that. I said I didn't think it was certified, because I don't think it is. Doesn't have the API logo on the jug. I think its probably good oil though, and it was fairly cheap, but I can't get it any more.

Cheapest "known brand" here would be Chevron 10-40 from Costco, but I won't buy that due to the deplorable Ecuador environmental record. I dare say they aren't too bothered though.

Yeah...any time I buy something chinese it comes with horrible, horrible remnants of cheap chinese oil. It's stench is unmistakable - like the smell of a harbor freight store, which you probably don't know. I've bought plenty of chinese engines who still have a few ounces of their test run oil in it...absolute trash. And STINKS!

Or any oil made in China really...I would not touch that. An off bulk brand from China? LOL! Or any brand of oil I found in a disgusting river! DOUBLE LOL!

I'm seriously not sure why somebody who cares so little about oil would have so many posts on this forum?

Very unlikely your PRC engines have ROC oil in them. That'd be..er..politically unacceptable. (Ooo...politics).

Re "so many posts", yeh, I increasingly wonder that myself.
