Isn't Rotella something you spread on toast and muffins?

T6 0w40 Rotella Here.

Like the fact it's got a lot of detergent, etc to de-soot diesel (carbon deposits). 0-40 Mobil is great too I'm sure but it's all anecdotal

And the proper s2 Oil filter which is most important. And good premix (redline, for now)

Don't forget most Renesis engines are pumping whatever is in the oil sump into the combustion chambers and the potential accumulation of additive deposits on the rotor seals might not be so beneficial ...
