Synthetic or Conventional motor oil in Kubota diesels

[GeoHorn]

Aint that the truth - but there have been those that have!!!


Funny how the first commercial SYNTHETIC oil was developed FOR the flying machines - JETS

HORTH-THIT. ( You can’t believe everything you read when “A-I” pops an answer on Giggle.)
Amsoil was never around Germany in WW2. It was first developed in the late 1870s in Germany and was widely produced during WW1/2 by Fischer and Tropsch.

The early (1960s) turbine oils used in Bristol, Rolls Royce, GE, Westinghouse, etc were ASTO 500 (Shell) and Schaeffer and Mobil. How do I know? I’m that old and flew those contraptions…and personally poured many hundreds of gallons of that stuff in those early “total-loss” lube-systems.

These two sentences seem to contradict each other. Can you clear up the confusion?

I have been running amsoil signature 15-40 in my L3410 for several years with no issues. I change it once a year.

It's good stuff. Over priced/hyped IMO but if it was competitively priced and easily available I'd run it.

Same here. For my diesels though I run purely Rotella T6. It's also Synthetic and has a great track record with the millions of miles driven with it in use. I normally get an oil analysis with the oil change on my F350 and I have never had a bad reading. It does lose viscosity over time, but not enough to be a concern.

Yes, Thank you for pointing out my poor sentence—construction.
I SHOULD have written :

“Amsoil was never around Germany in WW2.

Synthetic oil was first developed in the late 1870s in Germany and was widely produced during WW1/2 by Fischer and Tropsch” …And I should have clarified by adding …” long before Amsoil was established in the late 1960s in the U.S. “

Thx.

There used to be a product, I think they called it CQ, that would bind Molybdenum Disulfide to metal and was invented during WWII. Moly Black Gold was the product that contained this lubricant, and was a pyramid scheme gone bd, but the stuff did work. Apparently it was used in planes and tanks and kept the engines running longer when they lost oil. Metal discs treated with the MBG were put on a hot plate and the heat turned up and you could see the metal sweat as it heated up. When they were cooled down, it would get sucked back into the metal and left a fine sheen of Moly on the surface. It was based out of Canada and I have no idea where it went from there, but it was something to see in action.
