I am dealing with a JD lawn tractor with a Tuff Torq K46 transaxle. It appears the factory fill is john Deere Hi Gard-Hi Viscocity. They now recommending Their own Oil which is Tuff Torq 187Q0899000 oil. I do not know what it is. They will not publish any info on it. However they confuse the matter by saying other Transaxles in the same K46 family had 10w-30 or synthetic 5w-50 as the factory fill. These are basically the same style transaxles. It may be easier to figure out what is the better value choice if I knew what these mystery oils are basically. I have done some searches on this board and did not find anything helpful. Maybe I am not spelling everything perfectly. Sometimes the search just does not seem to do anything.
I was just going to use 5w-50. From what I have read, people are assuming the Tuff Torq is 5w-50. But after some thinking I want to use what is the best for this situation. I have read some have used 15w-50 and seem very happy. I assume they do not use it in the cold months.
Is there a break down for the average person to understand what these two mystical oils from JD and Tuff Torq are? Even knowing for sure the SAE viscocities would be helpful. Are they both Synthetic or semi or other? Etc. Is there something special about them that differentiates them from a 5w-50 motor oil? Thanks in advance to those who know and are willing to share.
