Oil prospecting.

Was down by the swollen river to get some "ground truth" shots for a remote sensing module I'm trying to put together and I found this, perhaps deposited by the receeding flood. Was on its side oozing a slick into the river. Seems to still be about 2/3 full.




I'll haved to decant it to make sure it hasn't got any river water in it (rain water would probably be OK).

Assuming it hasnt, what are the potential issues with using an oil that doesn't appear to carry an S rating?

Amsoil say no, but they don't say why.

If its OK, if I stay in Taiwan, with the stuff I already have, thats a lifetimes supply of oil.

Which is a bit depressing.
 
That looks like it's been refilled with used oil.

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

Could be, given the dirt, though from tilting the can, the content looks cleanish. I'll have a better idea when I decant it. Best guess is it was for irrigation pump lubrication, though there are some bank reinforcement works currently upstream.

If its dirty I'll take it for recycling and feel I've saved the environment a drop in the ocean of insult.

One washed up oil jug at a time! Ata boy!

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.
 
Anyway, how about the question?

Non S-rated oil in a petrol engine?

Issues?
 
HDEO in a gas engine - no problem. Have 15W-40 in my 911 right now.

That oil in anything - don't think so. It came out of the river. Throw it back.

Does the stuff in your 911 carry an S-rating?

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.

If you really wanted to use it, get it analyzed--only then will you know the real story. Everything posted here is speculation and should be treated as such.
 
HDEO are excellent for older petrol engines that require 40 grades and don't have too much emissions equipment, cats or egrs and such.
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.

Smelt unused too.

Before I considered using it I'd decant the whole thing and see whats at the bottom. I MIGHT then look into any DIY tests/comparisons with unused (might be able to get a little lab access, maybe a spectrphotometer, though I dunno if that'll be useful).

I probably wouldn't get a standard VOA/UOA done because I wouldn't know how to do that here and probably wouldn't want to pay for it if I did.

How do you mean "annoyed"?

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).

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?
