Has anyone switched to Rotella T5?
I was wondering if anyone had switched to Shell Rotella T5 10W-30 Synthetic Blend. If so, what year engine do you have, what did you switch from, and what are the results. I am thinking of switching. I have a 2005 KW with a Cat engine with 1,120,000 miles on it. I have not had it rebuilt. I run Shell Rotella Triple Protection 15W-40 now and get 7mpg.
Is this a good question?
