I just bought a really clean 1969 cat motor grader with a D333 motor. Any suggestions for motor oil? I run mystic 15w-40 syn blend in my 2015 power stroke and also in my 2015 Case 580 Super N backhoe which both were bought new but I don't know much about the new oil goin in the older machines

Appreciate any comments

I'll bet it calls for SAE 30 HD ... Not sure, but all the older CAT's I've worked on want that smile

My dad has an operators manual in his truck. Off the top of my head it is SAE30, and if it's really cold it gives advice on mixing kerosine to thin it out!

Shell Rotella T5 10W30 will provide start up protection you need and is better than any 30W from 40+ years ago.

Pretty much.

Any cheap 15W-40 now is better oil than what was available 40-50 years ago.

Since im not sure what oil was used in my grader previously Any reason I shouldn't convert to mystic 15-40 synthetic blend ? No worries of new oil consumption ?
I'm kinda old school and I was made to believe switching oil could cause oil consumption.

What would the oil used before your ownership have to do with anything since 1960 the grader has had more different oils than a horse has had shoes.

Understand this engine was produced well before 15W40 was available. I would recommend using SAE 40 oil if you don't need to do cold starting.

There are plenty of modern SAE 30 and SAE 40 grades out there. No VII's to shear down and they lube very well. There are some engines that will tear up any multi grade, so they are recommended for mono's only.

Just becasue it's a mono, does not mean it is "40 years old" ...

Your current 15W-40 will work good or be
