It would facilitate response if you would number each chapter in your book / post.
Meanwhile you may want to research the effects of ash, phosphorous and sulfur content in 2T oil relating to the potential effect on motorcycle valve stems.. the CB 1100 has 16 of them.
Another research suggestion would be regarding the additives used in 4T oil specifically for high RPM motorcycle engines.
When I buy a vehicle I service it as though I were going to keep it forever.
Sportster Doc,
Sorry you don't like my lengthy posts. You should see my CL ads! The people that buy stuff from me like the fact that I provide detailed information and answer all their questions before they ask, while others personally attack me for it. For them, I suppose they prefer the one grainy picture and ad text that says "come and get it".
You (and others) made a lot of points and I responded to each one, and that took some thought and typing.
I said I don't need a bypass and explained why, in that the oil is never going to get dirty enough, nor will I ride at subzero temperatures to need one.
I responded about the oil company marketing about dangerous zinc and phosphors with the argument that those have been phased out of modern oils. They are using an old argument that no longer applies and is invalid to make their marketing pitch.
I asked why the car detergent additives don't cause buildup on car pistons and valvetrains, but the marketing claims those will occur on bikes. You did not respond to that.
My Honda car redline is "only" 6700 rpm, while the CB1100 redline is 8500, a 27% difference. If I put fresh Mobil-1 full synthetic (no energy conserving) car oil in by CB1100 every 3,000 miles, that additional 27% rev increase is going to cause the oil to breakdown in that low interval? Lets not even get into the fact that you will live at 3-5,000 rpms for the overwhelming majority of the life of the motor, whether you are in your car, your Guzzi, your Can Am, or your CB1100.
Your response is I need to do more research.
I think I am being practical and logical (yes, and frugal too), not emotional about it.
So I ask, what in the motorcycle oils (additives) cost the manufacturer 400% more that justifies the retail price 400% increase? What research have you done you can point me to that answers that question?
Perhaps we can agree to disagree, but I am asking you to resist just responding to that only, and actually provide real counterpoints or answers to my questions.
