Shell Rotella T 10W30

[jeffmc]

Since Honda specs this weight, my question is how much different is the 10w30 Rotella T vs the 15w40 Rotella T. I realize it isnt JASO-MA certfied but is the formula the same just different viscosity. I used the T5 in a Nomad I had and had some slippage, so I am interested in the regular Rotella.

The biggest difference is the 5w40 is a Group III synthetic (XHVI) and the 10w30 is a syn blend. The 15w40 is made from Group II.

I think he means Rotella T 10w30 conventional, not T5 semi-synthetic.

Got my answer, good to know for the future


You're correct on all counts. The formulation for Shell Rotella T Triple Protection Oil SAE 10W-30 is similar to that of the SAE 15W-40 oil. We have not submitted the SAE 10W-30 oil for testing against JASO MA or MA2.

We would expect the frictional properties for the two oils to be similar, but cannot guarantee that the SAE 10W-30 oil will pass the JASO requirements.

That Rotella T (or T5) 10w-30 is good stout stuff. If my Goldwing was spec'd for 10w-30 (but it is 2 years too old), I'd run the T5 in a heartbeat.

But that is neither here nor there.

The OP is asking about T 15w-40 vs T 10w-30. Both of them are mineral oils.
