5400 miles on QS 5w-30 Full Syn. Not Euro.
Previous diet was 0w-40 Castrol.
Engine was quieter (not expected). Also noticed at least .6 mpg increase, but was more since I didn't reset MPG for each oil interval previously and did not for this one either. The average already present went up at least that amount. The first line (Ref. BL) is a virgin sample I sent in last year.
Also was "having fun" a couple of times, trying to get oil temp up, highest was 259 degrees, with 250+ hit more often. (Arizona summer).
Titanium is of course leftover from the 0w-40 Castrol. This was first change after the Castrol, no flush done. This QS 5w30 is in the sump again. Previous UOAs (all 0w-40 Castrol) in line for your viewing convenience.
