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.
