303 fluids were speced in the 60s and 70s... it replaced the type a hydraulic fluid that was 20wt oil with a red dye... The type F or 303 fluids had to have a viscosity stiffener added to extend the heat range performance of the oil over the type A fluids. It was suitable for most all older systems with no performance problems.
However in the 80s, much higher hydraulic pressures and much more heat required a newer more robust hydraulic package. Lots of tractors even had hydraulic coolers added also to help control the heat of higher pressures. 303 was never intended to be used in newer applications requiring better fluids and some applications requiring a synthetic blend of oils.
Side note: 303 fluids commonly used a whale oil additive as a viscosity improver and the world wide whale oil ban and treaty... forced the original specs to be banned. turns out there are now many other ways to improve viscosity performance of the oil. Muti weight oils are now common.
Now what was the basis of the law suit?? was it the banned whale oil or improper labeling in reguards to the ban?
