Factory oil recommendations (was Re: [Farmall] parts

[John Hall]

By the same logic wouldn't todays 30W oil be better than that of 50 years 
ago also? Regardless, we only ran one type of oil on our farm. It was used 
in everything except cars. Never had a failure related to oil that we were 
aware of. Used Phillips until we couldn't find it, then switched to Exxon. 
Both were diesel oils.

As for the Hy-tran, we used it in the red tractors and Hy-gard in the green. 
If we got caught without one or the other, we'd substitute. Never had a 
problem. I do remember a test IH put out in the 80's The dealer took about 4 
brands of hydraulic oil and put them in vials with so much water. The test 
was to show how well Hy-tran blended with impurities. The Hy-tran came in 
first , followed by a Quaker State I believe. I think Deere was third.

I don't know what was so special about it but the dealer my dad worked at 
sold a IH low-ash 30w oil. Had one customer swear that anything else he put 
in his Cadet would burn out, but the mower didn't use oil if he used the 
low-ash.

Just my opinions and recollections, worth about half what you paid for them 
:)
