Today I was in a brick factory and they showed me into their oil storage shed. In the middle of the dirt parking lot, in the middle of where they dig out the clay for the bricks, in high winds, they have a well ventilated shack with about 25 open drums of oil. One hand pump that they pass between open drums as needed to pump out what they are going to use. Among the oils: SAE 40 CC SAE 40 SF SAE 50 CC SAE 90 GL-3 SAE 140 GL-1 SAE 250 GL-1 ISO 68 hydraulic SAE 85W-140 GL-5(that they bought from me 4 years ago) SAE 80W-90 GL-5 (that they bought from me 4 years ago) (they say they haven't used much of this because it is too thin.) A Venezuelan ATF that didn't say Dexron or Type A or anything, but the 1 qt cans were rusty. With morning temperatures ranging from -2C to 16C, I asked where they were using those oils. The SAE 50 is for their newer gasoline engines, and newer diesel engines. The SAE 40 is for old stuff that they don't need to take care of. The various transmision oils no one could agree on where they were used, but basically said if it was cold they used the 90 and when it got warmer they used the 250. One mechanic said he used the Hydraulic 68 in the converters of the CAT and Komatsu loaders, but the other one insisted that he used the 85W-140 mixed with the 250 to protect it better. They had two greases, niether had EP, one was sodium, the other lithium. No one could agree on where each was used. They also use the greases to thicken the SAE 250 for the summer in diferencials on the pickups and trucks.
