Both dealers here use UDT for the RTV's. My RTV is a 2013 has not had any issues plus the manual says its ok. I also use UDT in my L3130GST with no issues (UDT is called for in the manual).
SUDT is just more expensive with no benefit that I can see in these machines.
Well it made difference here in both cases sorry you cannot notice.
