I have been using Castrol GTX 10w30 in my NH TC 35D. I have been told be a NH rep to use only NH oil. I change oil and NH filter every 50 hours. I am wondering if there is more than just a price difference in the oil. If there is a significant difference, is there something available from the autoparts store, as my NH dealer is about an hour away. Thanks ahead of time for any response.
