I have been using Rotella T 5W-40 Synthetic (Blue Bottle) in the past. I went to Walmart, Fleet Farm, and local auto stores but all I can get now is the Rotella T6 5W-40 Synthetic.
The T6 has API Service CJ-4/SM where as the T has API Service CI-4/SL in the circular API logo.
Has anyone used the T6 oil?
Thanks
