Valvoline™ 4-Stroke Motorcycle Full Synthetic 10W-40 Motor Oil

As I understand it, Rotella isn't sold as "approved" because they don't submit their oil for very expensive testing protocols to get that approval.

Just completed an oil and filter change on the poor, old, slow V-Max yesterday with the aforementioned Valvoline 10W-40 full synthetic motorcycle oil. purchased on line....

I was just looking at Vavoline web page and it listed Pros and Cons for the 10w40 motorcycle oil. In the Cons side it said you could only run 600 miles per oil change. What in the world are they talking about.

600 miles - ..... JMHO Mike

I agree with you, but look at their website.

Have you got a link to it?

Just my luck. Now I can't find the link. But if you search Vavoline 10w40 motorcycle oil it's there, I just can't stumble across it again.

I don't think you were on the Valvoline website. Maybe it was the Vavoline site.

Concur with BR although with BRP and L-M 5W40 I observed (via dashboard pressure gauge) the "knee" at 3K miles. Whereupon I changed oil.

The viscosity issue, at least for me, is not engine oil pressure (which is allowed to drop to 8.7psi at idle) but rather the HCM solenoids and multiplate pressure-engaged clutch. The HCM has its own oil pumps (scavenge, pressure) with two pressure circuits and the line pressure circuit operates at twice the maximum engine oil pressure. Although I'm sure the TCM has long-term trim to compensate for solenoid and clutch plate wear, my experience is my 95K miles transmission operates more smoothly and consistently with higher viscosity oil (in my case 15W-50). I have the parts to tap into the HCM oil pressure sensor (it's a standard 3-wire 5V transducer) but have been procrastinating.

That would be an interesting gauge to have. Let us know if you actually do it.
