Recommend engine oil for JD 4100 HST

No issues. I would not mix different brand oils. The additive packages are likely not the same. I would find a brand you trust and stick with it. Supertech is very good oil and has a large following.

Will I be ok running the Delo for a year than going back to supertech? I got 2 fills of each left now. I always replace the filter at the same time. 1 year or about 200h.

I have been using John Deere "50 Plus"15-40" oil in my JD 450c dozer and Massey 165 tractor for years. I wouldn't use anything else.

Walmart 15-40 sounds like a wonderful choice, you won't gain anything by using the Delo.
