For some of you skeptics on Shell Rotella T6......I use it in my 08 Toyota Matrix since new......it now has 170,xxx miles...runs like a champ.
I used it in my 2012 R6 which I bought new....This was a daily driver and a track bike...yes, I used this oil in my track bike that saw 14k rpm shift points continuously.....for entire track days which equates to about 5-7 sessions....each session being 10-15 minutes long.
I also use it for my dads 03 3500 Cummins RAM.
I will now use it for my Viking. Great stuff, cheap, and versatile. What more can you ask for?
