HIGHLY unlikely the slightly better efficiency of the Ultra vs. the EG is going go make a difference in engine life.

I was also speaking about the OP's 5K changes. After 5K the Ultra would definitely do a better job than the EG.
 
I've got a pure1 that I was going to use either on my autox/track car or my 1yr OCI commuter - sounds like I shouldn't put it on either given the latest report?
