The only 2 places that I've found locally that carry the 0W20 oil are WalMart and the dealer. I've had mine changed at Wally World each time with no problems. As I recall the whole thing (oil, filter, parts, labor) is around $25. Other quickie oil-change places were way high if they could "find" the right oil.

 

The dealer I bought my TCH from gave us certificates for a year of free service. So it will cost me nothing for the first year to use the dealer!!
