This is another UOA on our New Holland TS135A tractor. We continue to use if to run the feed wagon on our farm. Did 926 hours on this oil change using Mobil Delvac Super 1300 15w-40 we got real cheap with a rebate coupon. The previous oil changes were with Service Pro. I refilled with Shell Rimula 15w-40. Most recent UOA is to the right. Tractor had 9260 hours at time of oil change.

Over the summer, we used the tractor to run out bale grinder and the vents on the hood got plugged with debris and the tractor overheated to the point that the upper plastic tank on the radiator exploded. Literally. It cooled down and it still had some coolant in it so I drove it up to our shop, adjusted the valves while waiting for the new radiator to arrive since I hadn't done it yet on that unit, replaced the raditor, flushed the cooling system, and drained the engine oil with less than 200 hours on it. I had been adding Lubro-Moly oil additive and I think that might have been what led to the high lead numbers. This past oil change I did not use it and lead fell back down to an OK number. I use Lubro-Moly in a lot of our equipment and in some cases it has helped control oil consumption but in others it seems to result in higher lead numbers. I'll have to continue to test the others to see if the trend continues. I think I'll do 1000 hours or better for the next OCI to put it over 10,000 hours on the tractor.
