As I am new to the diesel world, I was curious as to what weights and brands of oils and hydraulic fluids everyone is using.
I have the cummins 8.3.
Your thoughts ?
Most use 15-40 weight oil.
Shell Rotella T and Delo 400 are popular brands and available at Walmart, etc.
Not sure there are any "bad" oils that are diesel rated.
Be sure to use a diesel oil rated CK4 NOT FA4.
As far as hydraulic oil, most of the reservoirs are labeled with what is recommend. Delo 400 15-40 for most year models.
Trying to not start the debate but many of us use Amsoil and install an 2nd oil filter that filters to 1 micron,we take oil samples and
can go upwards of 20K miles on a change.
Yes Amsoil all around.
15-40 oil in the motor and generator, 15-40 in the hyd tank, transend 295 spec fluid in the transmission, long life OAT red coolant the the radiators, 85-140 synthetic gear oil the rear axle.
Synthetic lubricants are good stuff and $$$, your call.
Amsoil all around and I am really pleased with the "Torque Drive "Synthetic in Allison, much better than the Transynd I took out.
As John 44 mentions we also have the bypass oil filter.
