Got a question. I have a full gallon of shell rotella T 15/40 in the garage, would it be good to use in the primary?
Should work fine in the primary if it is the dino. I use the synthetic in the Virago and have for years. The blue jug is synthetic.
The general opinion seems to be not to use synthetics in the clutch area on the HDs.
Rotella is a diesel rated oil and not supposed to be energy conserving.
Hopefully, they haven't change the formulation.
That said, I've got the Formula + in my primary.
