My brother told me today that his neighbor uses Amsoil Diesel oil in his diesel engine. He has the filter kit also. This guy states he has over 40,000 miles on the oil and gets an UOA every 5000 miles. I asked my brother to ask his neighbor what his TBN is. I would think this is an extreme oci. The guy also said he probably won't ever change his oil. I think I going get a hold of his UOA. Is this extreme or what?

That is plenty possible, but it also depends on filter changing and make-up oil. If you can get the UOA, and he allows it, post it for us all to see.

A uoa every 5k miles must be and expensive way to handle routine maintenance.

If you read some of the Amsoil literature or articles online, you'll find a rather dated story about a guy who went over 400,000 miles on his Amsoil diesel oil without a drain. Just changed filters and topped off the oil in his class 8 Mack truck. I believe his name was Haywood Gray and his used oil analysis came back good every time. Engine teardown later showed engine still in great shape. I'm thinking he was also running their bypass filter, too.

You gotta remember, some of these diesel engines have massive sump capacities

And many of these diesels operate in their sweet spot, warm, even load, long runs.

If it's a turbo, he is flirting with disaster.

And they have bypass oil filters to remove extremely small particles.

and in 400k miles, what was the cost of UOA's verus oil changes???

Mori you beat me too it, as soon as I saw the title I was going to respond with a bunch of "!"

 

[pp_rp]

It is a turbo diesel. wouldn't you think the TBN would be near 0?

 

[Syntec-Man]

the tbn must be zero

What's the big deal go the diesel engine UOA section on this site. There is a guy with 70000 miles on Schaffer's...

His numbers look got but it doesn't show his TBN. That's my concern when running oil this long.

For the price of a UOA and a filter every 5,000 miles I would just change the oil and filter and be done with it.

Seems like a potentially expensive way to make conversation.
