@barbraabsalom4531 Most of the wear particles are no ferrous, so a magnet is not really much use. On a cast steel block, with cast steel head, it is a good thing, but with modern engines the only thing it will pick up is wear particles from the rings, and they likely will be caught in the oil filter anyway.

You want an oil that is stinky out the bottle get some genuine WAP high pressure pump oil. it stinks worse than burnt gear oil even new, and only gets a stronger smell with age and degradation, especially if it gets water in it.

I took oil to a recycler, but remember that if the oil is mixed in the drum, old oil with gear oil or water, that entire drum is going to be used as burning oil, or added to bunker oil as a reducer, or used to make roads. Old oil take to the recycler in containers, and let them keep it that way. I took 2 drums of gear oil there, and they liked it, clear, though it was 20 years old oil, but it is still recyclable, and they pay for old oil that is clear much better than for mixed oil. The dealership next door abandoned premises, and in there was a 44gallon drum of mixed oil. I called for my usual 5 gallon pick up of used oil from machines, and asked them to take the drum. The amount they paid for the 44 gallon drum full, which went drum and all, was a tenth of the price they paid for my old oil, but they wanted the drum as well, useful things for a recycler to keep around.

@motleydude73 10 and 15k intervals is the manufacturer saying that the engine will make it out of warranty with that change interval, with only a tiny amount breaking within that time and distance. Keeping the car shorter, keep to the interval, want to keep it till it falls apart change more often, and you will see the difference.

@motleydude73 They also say that things like plugs, and non motor oil, is a lifetime thing. Yet plenty of automatic transmissions and CVT fail just outside warranty. The manufacturers have tested, and found, that lifetime, and also the minimum level of service required to reach it without failure. Yes there are outliers, like the car that is driven long distance, dry climate, all the time, which reaches a million miles, but the same one next off the line, nominally identical, is driven short distances, wet climate, and the engine and trans die about the same time as the body does, with the same service intervals.

@motleydude73 Renault Citroen Peugoet and Nissan had it down to a fine art, making a car that would basically fall apart after 7 years in the typical EU driving cycle. They never sold them in the US market for some reason, but garnered a bad reputation in the rest of the world for that.

@motleydude73 They did get a lot of blow back from that.

@motleydude73 Agree with that, sister had a 1990's Nissan, and that thing just ran, till it got stolen. However was not built in the EU, but in South Africa, where they build them a lot tougher to survive local conditions. The old saying is that with a locally built Toyota everything keeps falling off, but the engine and drivetrain keeps on rolling along. There are thousands of Toyota Quantum minibus taxis that have rolled over the million mark, a few times, along with old E20's and Super 16's as well. The competition does not make it that far.

If you live where there is no snow the 0W16 oil will work fine, as the engine oil with 0W8 is really for cold climates, and for fuel economy, as the engine is not really much changed for the last decade, where it was fine to use 10W30 oil, but the lighter oil relates to a slightly better fuel economy in testing.

@barbraabsalom4531 Transmission is different, because all steel gears and sliding surfaces, but an engine now has very little steel in it, all aluminium. I have stuck magnets into the pan of old oil, and got nothing sticking to them, but gearboxes you get wear particles. Magnet in a trans works, at least getting half the debris out, though the clutch wear is not touched much. And yes manufacturers only worry about warranty, so build it good enough to last that long, and a little more so the ones with bad tolerancing and flaws will all get out before failing.

Also remember the most common part of any additive is that 90% is actually straight engine oil.
