Why only 1500 milies?: when i did research there was no rotella 15w40 UOA, so i wasn't sure how many milie i can run with this oil. That is one reason why i did only 1500.

Under 1000 milies, i did a lot pulls during the day and night. After 1k milies, i went pretty easy on because my tranny issue. I also had 600 milies road trip with total 3 stops for gas. Plus i used turbo timer, avg 30 sec ~ 1 min.

UOA:


I think the oil did pretty good and result is good just like i thought...Great oil IMO.
I'm going to use this oil for summer and rotella T6 5w40 for colder days.

 

It's always nice to see UOA. Good results!

 

Yep. I will try get longer UOA next time when i use this oil. I now running 5w40.

 

I run the 5w40 in mine. So far it has been great!

 

Is this the synthetic version I think called Rotella T ?

Cheers A .

 

This is dino oil. If im right, Rotella t6 5w40 is only synthetic in us.

 

You can get in Australia if you know where to look , T6 that is .
