I have heard of a number of people using the Mobil 15W50 but not the 10W40. It would be REALLY nice to know if it is essentially identical to the MC version. The "No comment on that" comment is interesting!Mobil 1 10w-40 high mileage oil does NOT have the energy conserving decal. I have run this oil for nearly 77,000 miles in the FJR and ran it for 40,000 miles on my Gen 1 FZ1.
I actually talked to an engineer from Mobil 1 at SEMA in Las Vegas years ago. I ask him if he could tell me the difference in their “motorcycle” 10w-40 oil vs the high mileage “car” 10w-40 oil. He responded, “ I have no comment on that”.
