This is a couple UOAs from a Caterpillar 938H loader we bought for our farm about a year ago. We use this loader almost exclusively to load the feed wagon for cattle. Especially this time of year, it is left to idle a lot between loads on the wagon. Using a Caterpillar 269-8325 oil filter and an LF777 bypass filter that I installed. Using Service Pro 15w-40 oil.
